== Introduction ==
A small guide to show the communication via I2C between the Arduino (RPi-ShieldBridge) and Raspberry Pi.
The I2C pins of the Raspberry Pi are connected to the AVR and the Arduino Shield connectors (SDA+SCL) on the RPi-ShieldBridge.
== Préparer ==
Téléversez le sketch/croquis suivant sur votre RPi-ShieldBridge.
<nowiki>#include <Wire.h>
#define ADDRESS 0x30
void setup()
{
pinMode(13, OUTPUT); // set pin 13 as output (LED connected)
digitalWrite(13, LOW); // set pin 13 to low (0V)
Wire.begin(ADDRESS); // join I2C bus with respective address
Wire.onReceive(receive); // receive data function
Wire.onRequest(request); // send data function
}
void loop()
{
// do nothing
}
void receive(int numBytes) // function that runs when data is received
{
unsigned char c;
while(Wire.available())
{
c = Wire.read();
if(c == 0x00) // LED off, if byte equals 0
{
digitalWrite(13, LOW);
}
else if(c == 0x01) // LED on, if byte equals 1
{
digitalWrite(13, HIGH);
}
}
}
void request() // function that runs when data is requested
{
Wire.write(0xAA); // send 0xAA
