Hello,
i have read enteriely the tuto : https://www.dexterindustries.com/howto/connecting-ev3-arduino/
and after several test, nothing are working…
I have the breadboard adapter for lego and Arduino Uno.
I wanted to send a data from my arduino to EV3’s screen.
But nothing happenned.
here is the Arduino code :
#include <Wire.h>
#define SLAVE_ADDRESS 0x04
void setup()
{
Serial.begin(9600); // start serial for output
Wire.begin(SLAVE_ADDRESS);
Wire.onReceive(receiveData);
Wire.onRequest(sendData);
Serial.println("Ready!");
}
int val,flag=0;
void loop()
{
if(flag==1)
{
Serial.print(val);
flag=0;
}
}
void receiveData(int byteCount)
{
while(Wire.available()>0)
{
val=Wire.read();
flag=1;
}
}
// callback for sending data
void sendData()
{
Wire.write(0x45);
}
and here the Mindstorms program :
