RP6 ArduIO Erweiterungsmodul
Die RP6-ArduIO Erweiterungsplatine (siehe auch das Vorgängerprojekt,die RP6-MultiIO-Erweiterungsplatine) im üblichen RP6-Layout ist als reine I2C-Erweiterung sowohl für den RP6, als auch für Arduino-Boards und –Shields gedacht. Entwickelt wurde sie zusammen mit einigen Mitgliedern des Roboternetzes von fabqu (Hardwarearbeiten) und Dirk (Softwarearbeiten).
Eine Kurzbeschreibung der RP6-ArduIO Erweiterungsplatine findet ihr HIER.
Umfangreiche Dokumentation, sämtliche Beispielprogramme und Bibliotheken, Daten, Teilelisten und eine Lötanleitung finden sich unten in den Weblinks.
Hardware
Der Hardware-Artikel befindet sich HIER.
Software
Hier geht es um die Software für das von fabqu designte ArduIO Board. Für dieses Board soll es eine gemeinsame Library für die drei wesentlichen Plattformen des RP6-Systems und eine Library für den Arduino UNO geben. Ob auch eine Library für die RP6 CCPRO M128 veröffentlicht wird, ist noch offen.
RP6 M256 WIFI, CONTROL M32, BASE
Für die RP6 M256 WiFi, RP6 CONTROL M32 und RP6(v2) Base gibt es hier eine gemeinsame ArduIO Library. Die nachfolgenden Demos zu den einzelnen RP6-Mikrocontroller-Systemen nutzen diese Library.
ArduIO Library
Hier findet ihr die neue AVR-GCC Library für das ArduIO Board. Sie ist ausgelegt für die RP6 M256 WiFi, die RP6 CONTROL M32 und die RP6(v2) Base. Für die RP6 CCPRO M128 wird es vielleicht eine eigene Library geben.
Die Library für das Ardu IO Projekt Board (= "ArduIO") geht von folgenden Voraussetzungen aus:
- Der RP6(v2) Roboter (= "BASE"), die RP6 CONTROL M32 (= "M32") oder RP6v2 M256 WiFi Platine (= "M256") wird für die Ansteuerung der ArduIO benutzt.
- Die BASE, M32 oder M256 ist der I2C-Bus Master.
- Die I2C-Bus Geschwindigkeit beträgt 100 kHz.
- Alle Hardware-Komponenten der ArduIO sind aufgebaut (1).
- Alle Jumper auf der ArduIO sind in ihrer Standardstellung (2).
- Die ArduIO ist mit dem XBUS der BASE, M32 oder M256 1:1 verbunden.
Zu (1): Wenn nicht alle Komponenten aufgebaut sind, sind die zugehörigen
Funktionen natürlich nicht funktionsfähig und können nicht benutzt
werden.
Zu (2): Siehe folgende Abbildung!
Standard-Jumperstellung
Hinweis: Die Jumper sind orange eingezeichnet!
Die Jumper der Stromversorgung (S1, JP_5V, JP_UB, JP_LOAD) wurden nicht berücksichtigt!
Die Library (Software-Bibliothek) besteht aus drei Teilen:
- Dem Configuration Header -> Hier stehen alle Definitionen und Festlegungen, die der grundlegenden Konfiguration der ArduIO dienen. Diese Datei kann auf die eigenen Hardware-Voraussetzungen angepaßt werden, ohne dass die eigentliche Library (Header und Source) verändert werden muss.
- Dem Library Header -> Hier gibt es Definitionen, Variablen- und Funktionsdeklarationen für die Library.
- Der Library Source -> Das ist die eigentliche Library.
Configuration Header
Diese Datei ist der "Configuration Header" der neuen ArduIO Library. Sie gehört in den Ordner /.../RP6Lib/RP6common/.

~ There is also a macro int_status_changed(),

~ Hints: - You can use task_RP6_ArduIOSystem()
~ instead of THIS task! Do NOT use both
~ tasks together!
~ - You should only use this task, if you
~ have to read ALL digital and analog
~ Arduino Uno Expander input portpins!
~ - Digital portpins can be read, if they
~ were configured as INPUTs before:
~ configArduIO_IO2(0b1111111111111111);
~ - Digital portpin input values can be
~ inverted with the function
~ invertArduIO_IO(2,invrt)!
~ - PCA9535 (2) INT can only be read, if
~ the corresponding jumper (JP_INT3V3)
~ is CLOSED:
~ INT1 -> Pins 1-2 (PCA9535 (2) INT)

RP6 M256 WIFI
Die Demos für die RP6 M256 WiFi (und -wenn ihr wollt- auch eure eigenen Programme) nutzen die ArduIO Library, s.o.!
Config
Diese Datei enthält nur die Information, welches RP6-Mikrocontroller-System (RP6 Base, RP6 CONTROL M32, RP6 M256 WiFi) das ArduIO Board ansteuert. Sie gehört in den Projektordner.

/** * Settings for the RP6_ArduIO Library */ #ifndef RP6_ARDUIOCONFIG_H #define RP6_ARDUIOCONFIG_H /** * Define the target here: * (Use only ONE of them! Never two or three!) */ //#define ARDUIO_RP6BASE //#define ARDUIO_RP6CONTROL #define ARDUIO_RP6M256WIFI #endif

Demos der M32 anpassen
Es ist einfach, die M32 Demos an die M256 anzupassen. Die ArduIO Library braucht nicht verändert zu werden.
Folgende Anpassungen müssen gemacht werden:
- #include "RP6ControlLib.h" ==> #include "RP6M256Lib.h" - initRP6Control(); ==> initRP6M256(); - getPressedKeyNumber() ==> Tastenabfrage komplett entfernen!
Zusätzlich können bei der M256 alle UART-Ausgaben auf WiFi umgeleitet werden. Dazu muß an die UART-Ausgabebefehle "_WIFI" angehängt werden.
Beispiel:
- writeString_P("Text"); ==> writeString_P_WIFI("Text");
Die Funktion writeDouble() der M32 Demos kann für die WiFi-Ausgabe ersetzt werden durch:
void writeDouble_WIFI(double number, uint8_t width, uint8_t prec)
{char buffer[width + 1];
dtostrf(number, width, prec, &buffer[0]);
writeString_WIFI(&buffer[0]);
}
RP6 CONTROL M32
Diese Demos für die RP6 CONTROL M32 (und -wenn ihr wollt- auch eure eigenen Programme) nutzen die ArduIO Library, s.o.!

Demo 1
Die Demo 1 besteht eigentlich aus ZWEI Testprogrammen. Wird sie so kompiliert, wie sie hier steht, erfolgt ein SCHREIB-Test (Output) auf allen Funktionen der ArduIO. Wird die Definition "WRITE_TEST" auskommentiert, erfolgt ein LESE-Test (Input).

Demo 4
Die "Demo 4" ist eigentlich kein fertiges Programm, sondern eine Aufgabe für euch. Es soll dabei um die RP6-Beleuchtung ("Scheinwerfer") gehen, die als "Überraschung" zum ArduIO Board gehört. Wenn man die 5 kleinen Platinen so anschließt, wie im Bild rechts eingezeichnet, dann steuert der I/O Expander 1 mit seinem zweiten Port (GP110..GP117) die Scheinwerfer an.
Was ist jetzt die Aufgabe?
==> Schreibe die Demo "RP6Control_09_Move" so um, dass die jeweilige Bewegung
des RP6 mit der passenden Fahrzeug-Beleuchtung erfolgt. Im Ergebnis soll
der RP6 sich genau so bewegen, wie in der Original-Demo.
==> Bei Links-Rotation soll der linke Blinker, bei Rechts-Rotation der rechte
Blinker blinken. Bei Vorwärts-Fahrt soll das Fernlicht leuchten, während
der Rotation das Abblend-/Standlicht.
==> Am Ende der while(true) Schleife (nach der Rechts-Rotation) soll der RP6
anhalten, und es soll für 15 Sekunden nur das blaue Blinklicht an sein,
bevor der Bewegungsablauf am Anfang der while(true) Schleife neu startet.
Das ist zu schaffen, oder?
Zur Ansteuerung der Scheinwerfer gibt es hier eine "Task", die ihr verwenden könnt:

Viel Erfolg!
Tipps:
- Die Carlights Task funktioniert nur in einer schnellen Schleife!
- Damit scheidet die Lösung mit den Bewegungsbefehlen (move, rotate) im Modus "BLOCKING" aus, und man muss sie in nicht blockierende Bewegungsbefehle (4. Parameter "NON_BLOCKING") umändern.
- Seht euch auch folgende nützlichen Befehle/Funktionen an:
- isMovementComplete()
- task_checkINT0()
- task_I2CTWI()
Erklärung
RP6 BASE
Die Demos für die RP6(v2) Base (und -wenn ihr wollt- auch eure eigenen Programme) nutzen die ArduIO Library, s.o.!
Config
Diese Datei enthält nur die Information, welches RP6-Mikrocontroller-System (RP6 Base, RP6 CONTROL M32, RP6 M256 WiFi) das ArduIO Board ansteuert. Sie gehört in den Projektordner.
Datei RP6_ArduIOConfig.h:
/** * Settings for the RP6_ArduIO Library */ #ifndef RP6_ARDUIOCONFIG_H #define RP6_ARDUIOCONFIG_H /** * Define the target here: * (Use only ONE of them! Never two or three!) */ #define ARDUIO_RP6BASE //#define ARDUIO_RP6CONTROL //#define ARDUIO_RP6M256WIFI #endif
makefile (z.B. für Demo 1):
... TARGET = RP6Base_ArduIO_01 ... SRC += $(RP6_LIB_PATH)/RP6common/RP6_ArduIOLib.c ...
Demos der M32 anpassen
Es ist einfach, die M32 Demos an die RP6 Base anzupassen. Die ArduIO Library braucht nicht verändert zu werden.
Folgende Anpassungen müssen gemacht werden:
- #include "RP6ControlLib.h" ==> #include "RP6RobotBaseLib.h" - initRP6Control(); ==> initRobotBase(); - initLCD(); ==> LCD-Ausgaben komplett entfernen! - ==> powerON(); - setLEDs(0b1111); ==> setLEDs(0b111111); - getPressedKeyNumber() ==> Tastenabfrage komplett entfernen!
RP6 CCPRO M128
Für die CCPRO M128 soll es hier evtl. eine eigene ArduIO Library geben. Die nachfolgenden Demos nutzen diese Library.
ArduIO Library
Schauen wir mal, ob es hier eine ArduIO Library für die CCPRO M128 geben wird. Das hängt sicher auch davon ab, ob einer der Nutzer das ArduIO Board mit der M128 betreiben will.

Arduino UNO
Das Ardu IO Projekt Board (= "ArduIO") ist nicht nur eine RP6 Erweiterungsplatine, sondern auch ein Arduino Shield. Damit stellt die ArduIO eine Verbindung zwischen dem RP6-System und der "Arduino-Welt" dar. Als Arduino Shield kann die ArduIO auf eine Arduino UNO Platine gesteckt werden, die dann alle Funktionen der ArduIO steuern kann. Weitere Arduino Shields können wiederum auf die ArduIO gesteckt werden. Die Verbindung zum RP6-System kann dann über die XBUS- und USRBUS-Stecker der ArduIO erfolgen.
HINWEIS: Wenn hier vom Arduino UNO die Rede ist, dann sind zur Ansteuerung des RP6 ArduIO Boards natürlich auch alle weiteren Arduino BOARDS nutzbar, die selbst einen Sockel für Arduino Shields haben. Die ArduIO kann also z.B. auch auf dem neuen Arduino TRE (ARM Cortex A8!) oder dem pcDuino3 (ARM Cortex A7!) genutzt werden. Auch durch ARM Cortex M0..M4 Boards (z.B. M4: Nucleo STM32F401RE oder M3: LPCXpresso Board) kann das RP6 ArduIO Board (und damit auch der RP6(v2)!) angesteuert werden. Die Adapterplatine Raspberry Pi to Arduino shields connection bridge oder der ELV Raspberry Adapter für Arduino Shields RPi-AA1 ermöglichen, das RP6 ArduIO Board auf dem Raspberry Pi einzusetzen. Mit Hilfe einer Adapterplatine (Allnet 113079 Breakoutplatine 2in1 für Banana Pi + Arduino I/O) ist auch der Übergang zum Banana Pi möglich. Die folgende ArduIO Library kann natürlich nur auf Plattformen eingesetzt werden, die Software-kompatibel zum Arduino UNO sind!
ArduIO Library
Hier findet ihr die neue Arduino Library für das ArduIO Board.
Die Library für das Ardu IO Projekt Board (= "ArduIO") geht von folgenden Voraussetzungen aus:
- Ein Arduino UNO Board wird für die Ansteuerung der ArduIO benutzt.
- Der Arduino UNO ist der I2C-Bus Master.
- Die I2C-Bus Geschwindigkeit beträgt 100 kHz.
- Alle Hardware-Komponenten der ArduIO sind aufgebaut (1).
- Alle Jumper auf der ArduIO sind in ihrer Standardstellung (2).
- Die ArduIO ist auf das Arduino UNO Board aufgesteckt.
Zu (1): Wenn nicht alle Komponenten aufgebaut sind, sind die zugehörigen
Funktionen natürlich nicht funktionsfähig und können nicht benutzt
werden.
Zu (2): Siehe folgende Abbildung!
Standard-Jumperstellung
Hinweis: Die Jumper sind orange eingezeichnet!
Die Jumper der Stromversorgung (S1, JP_5V, JP_UB, JP_LOAD, JP_5V_ARD, JP_3V3_ARD, JP_UBAT_ARD) wurden nicht berücksichtigt!
Die Library (Software-Bibliothek) besteht aus drei (optional vier) Teilen:
- Dem Library Header -> Hier gibt es Definitionen, Variablen- und Funktionsdeklarationen für die Library.
- Der Library Source -> Das ist die eigentliche Library.
- Der Datei keywords.txt -> Hier stehen alle Bezeichnungen, die im Editor der Arduino IDE markiert (farblich hervorgehoben) werden.
- Dem optional einzubindenden Definitionen Header -> Hier befinden sich ergänzende Definitionen, deren Benutzung nicht erforderlich ist, aber evtl. das eigene Programm besser lesbar macht.
Die Dateien dieser Arduino Library gehören ins Verzeichnis /.../libraries/RP6_ArduIO/.

Zu *) Pins von JP_PWMx, die geschlossen (mit einem Jumper überbrückt) werden müssen. ACHTUNG: Wenn auf JP_PWMx Pins überbrückt sind, muss UNBEDINGT der zugehörige Jumper am Expander Sockel (Pin 3, 5, 6, 9..11) auf JP_ARD2 ABGEZOGEN werden!
Arduino-Welt und RP6-System
Mit dem Arduino Expander Sockel auf dem ArduIO Board (Stecker-Belegung siehe hier!) ist es erstmals möglich, Arduino Shields im RP6-System zu nutzen, indem sie auf das ArduIO Board aufgesteckt werden, das wiederum auf dem RP6(v2) sitzt und mit ihm über den XBUS und (optional) den USRBUS verbunden ist. Wenn man Arduino Shields auf dem ArduIO Board nutzt, steuert der Prozessor der RP6 BASE (oder einer der Zusatzplatinen CONTROL M32 oder M256 WIFI) die Funktionen der ArduIO und des/der darauf sitzenden Arduino Shields.
Dabei erfolgt diese Steuerung der ArduIO Funktionen über den I2C Bus. Das Arduino Shield, das auf der ArduIO sitzt, kann dann ebenfalls über I2C und/oder über die digitalen und analogen Portpins des Arduino Expander Sockels angesteuert werden. Wie ein Shield angesteuert wird, hängt von der Art des Shields ab.
Eine weitere Option ist das Aufstecken des ArduIO Boards auf einen Arduino UNO. Optional können noch weitere Arduino Shields auf das ArduIO Board aufgesteckt werden. Der Arduino UNO steuert dabei alle Funktionen der ArduIO und des/der optional darauf sitzenden Arduino Shields.
Dabei erfolgt diese Steuerung der ArduIO Funktionen über den I2C Bus. Das Arduino Shield, das auf der ArduIO sitzt, kann dann ebenfalls über I2C und/oder über die digitalen und analogen Portpins des Arduino Expander Sockels angesteuert werden. Wie ein Shield angesteuert wird, hängt von der Art des Shields ab.
Zuletzt gibt es auch noch die Option, die Kombination aus ArduIO Board und Arduino UNO auf dem RP6(v2) einzusetzen und zusätzlich optional weitere Arduino Shields auf die ArduIO aufzustecken. Dadurch entsteht quasi ein "Multi-Prozessor-System". Man kann völlig frei entscheiden, welches Prozessor-System (aus dem RP6-System oder Arduino UNO) das ArduIO Board und die weiteren Arduino Shields ansteuert.
Was gibt es bei diesen drei Anschluss Optionen des ArduIO Boards zu beachten? Hier soll versucht werden, die wesentlichen Aspekte zu beschreiben.
RP6, ArduIO und Arduino Shield(s)
Dies ist die typische Nutzung des ArduIO Boards und mindestens eines (weiteren) Arduino Shields im RP6-System. Ein Arduino UNO ist dabei NICHT angeschlossen. In dieser Konfiguration steuert der Prozessor des RP6-Systems (auf der RP6 BASE, CONTROL M32 oder M256 WIFI) die ArduIO über den I2C Bus. Das Arduino Shield wird -je nach Art des Shields- ggf. auch über den I2C Bus angesteuert bzw. ausgelesen. Darüber hinaus "simuliert" das ArduIO Board die digitalen und analogen Portpins am Arduino Expander Sockel, die das Shield braucht und die sonst vom Arduino UNO belegt würden. Zur Ansteuerung der ArduIO kann man die ArduIO Library für die RP6 BASE, CONTROL M32 oder M256 WIFI verwenden. Die dazu gehörigen Demos zeigen, wie das geht. Die Software zur Ansteuerung des (zusätzlichen) Arduino Shields muss man natürlich selbst schreiben.
Hinweise zum Betrieb der ArduIO und mindestens eines (weiteren) Arduino Shields im RP6-System:
- Jumper wie im Abschnitt der Library unter "Standard-Jumperstellung" setzen.
- Bitte beachten, dass zunächst KEINE Jumper auf JP_ARD2 (digitale Portpins) und JP_ARD3 (analoge Portpins) gesetzt werden.
- Wichtig ist die Art der Stromversorgung:
- Die Versorgung des Arduino Shields erfolgt über 3,3V, 5V oder Vin?
- Diese Jumperstellungen werden hier nicht beschrieben. Siehe Hardware-Artikel!
ACHTUNG: Bei der Festlegung der Stromversorgung sehr sorgfältig vorgehen!!!
- Es ist je nach Art der weiteren Shields zu entscheiden, wie diese angesteuert bzw. genutzt werden:
- Wird das (zusätzliche) Shield über den I2C-Bus angesteuert?
- Wird das (zusätzliche) Shield über die serielle Schnittstelle oder SPI angesteuert?
- Welche digitalen Portpins des (zusätzlichen) Shields werden WIE (Eingang, Ausgang, PWM...) genutzt?
- Welche analogen Portpins des (zusätzlichen) Shields werden genutzt?
- Abhängig vom (zusätzlichen) Arduino Shield sind nach Beantwortung der o.g. Fragen verschiedene Jumperstellungen von JP_ARD2 und JP_ARD3 erforderlich. Grundsätzlich sollten nur DIE Jumper auf JP_ARD2 und JP_ARD3 aufgesteckt werden, die AUSSCHLIESSLICH für die Kommunikation zwischen ArduIO Board und dem/den (zusätzlichen) Shield(s) erforderlich sind!
- Braucht das (zusätzliche) Shield PWM-Ausgänge für seine Funktion, sind auch ggf. Jumper auf JP_PWM1..3 zu setzen.
HINWEIS: Immer wenn Jumper auf JP_ARD2, JP_ARD3 oder JP_PWM1..3 aufgesteckt sind, sind Hardware-Konflikte zwischen Portpins des ArduIO Boards und des/der (zusätzlichen) Arduino Shields möglich! Diese Konflikte können zu Beschädigungen aller Platinen führen!
Ist die Hardware-Konfiguration -wie oben beschrieben- abgeschlossen, kann die ArduIO vom RP6-System über den I2C Bus angesteuert bzw. ausgelesen werden. Das (zusätzliche) Arduino Shield wird ggf. ebenfalls über den I2C Bus angesteuert, zusätzlich "simuliert" das ArduIO Bord -wie gesagt- die digitalen und analogen Portpins am Arduino Expander Sockel, die das Shield braucht.
Arduino UNO, ArduIO und (optional) Arduino Shield(s)
Wenn man das ArduIO Board als reines Arduino Shield nutzen will, dann ist das natürlich gut möglich. Es werden dann keinerlei Bestandteile des RP6-Systems angeschlossen. Der Arduino UNO steuert das ArduIO Board komplett über den I2C Bus. Zur Ansteuerung kann man die ArduIO Library für den Arduino UNO verwenden. Die dazu gehörigen Demos zeigen, wie das geht.
Hinweise zum Betrieb der ArduIO als reines Arduino Shield (ohne RP6 und OHNE weitere Shields):
- Jumper wie im Abschnitt der Library unter "Standard-Jumperstellung" setzen.
- Bitte beachten, dass zunächst KEINE Jumper auf JP_ARD2 (digitale Portpins) und JP_ARD3 (analoge Portpins) gesetzt werden.
- Wichtig ist die Art der Stromversorgung:
- ArduIO wird vom Arduino UNO versorgt oder umgekehrt?
- Die Versorgung erfolgt über 3,3V, 5V oder Vin?
- Diese Jumperstellungen werden hier nicht beschrieben. Siehe Hardware-Artikel!
ACHTUNG: Bei der Festlegung der Stromversorgung sehr sorgfältig vorgehen!!!
Ist die Hardware-Konfiguration -wie oben beschrieben- abgeschlossen, kann die ArduIO vom Arduino UNO über den I2C Bus angesteuert bzw. ausgelesen werden.
Wie bei jedem Arduino Shield können auf das ArduIO Board weitere Arduino Shields aufgesteckt werden.
Hinweise zum Betrieb der ArduIO als reines Arduino Shield (ohne RP6 und MIT weiteren Shields):
- Es gelten die selben Hinweise wie oben für den Betrieb der ArduIO als reines Arduino Shield (ohne RP6 und OHNE weitere Shields) beschrieben.
- Es ist je nach Art der weiteren Shields zu entscheiden, wie diese angesteuert bzw. genutzt werden:
- Wird das (zusätzliche) Shield über den I2C-Bus angesteuert?
- Wird das (zusätzliche) Shield über die serielle Schnittstelle oder SPI angesteuert?
- Welche digitalen Portpins des (zusätzlichen) Shields werden WIE (Eingang, Ausgang, PWM...) genutzt?
- Welche analogen Portpins des (zusätzlichen) Shields werden genutzt?
- Sollen die digitalen bzw. analogen Portpins des (zusätzlichen) Shields durch den Arduino UNO oder vom ArduIO Board angesteuert bzw. ausgelesen werden? HINWEIS: In der Regel wird das der Arduino UNO machen!
- Abhängig vom (zusätzlichen) Arduino Shield sind nach Beantwortung der o.g. Fragen verschiedene Jumperstellungen von JP_ARD2 und JP_ARD3 erforderlich. Grundsätzlich sollten nur DIE Jumper auf JP_ARD2 und JP_ARD3 aufgesteckt werden, die AUSSCHLIESSLICH für die Kommunikation zwischen ArduIO Board und dem/den (zusätzlichen) Shield(s) und/oder dem Arduino UNO erforderlich sind!
- Braucht das (zusätzliche) Shield PWM-Ausgänge für seine Funktion, sind auch ggf. Jumper auf JP_PWM1..3 zu setzen.
HINWEIS: Immer wenn Jumper auf JP_ARD2, JP_ARD3 oder JP_PWM1..3 aufgesteckt sind, sind Hardware-Konflikte zwischen Portpins des Arduino UNO, des ArduIO Boards und des/der (zusätzlichen) Arduino Shields möglich! Diese Konflikte können zu Beschädigungen aller Platinen führen!
RP6, Arduino UNO, ArduIO und (optional) Arduino Shield(s)
Das ist dann das schon erwähnte "Multi-Prozessor-System". Über das ArduIO Board können alle Prozessoren des RP6-Systems (auf der RP6 BASE, CONTROL M32 oder M256 WIFI) mit dem Prozessor des Arduino UNO zusammen arbeiten. Diese Zusammenarbeit erfolgt primär über den I2C Bus.
Wenn man diese Konfiguration nutzen will, gibt es neben den schon oben angeführten Punkten zu beachten bzw. zu klären:
- Nutzung des I2 Bus:
- Soll ein GEMEINSAMER I2C Bus (des Arduino UNO und des RP6-Systems) benutzt werden?
- Welches Prozessorsystem ist der I2C Master?
- Welche Aufgabe haben die einzelnen Prozessorsysteme?
- Welches Prozessorsystem steuert die Funktionen des ArduIO Boards?
- Ansteuerung des/der (zusätzlichen) Arduino Shields:
- Abhängig von der Art des Arduino Shields.
- Hinweise dazu siehe z.B. oben unter "Hinweise zum Betrieb der ArduIO und mindestens eines (weiteren) Arduino Shields ..."!
