1. Wires are:
Arduino (analog in A5) – Dexter (SCL)
Arduino (analog in A4) – Dexter (SDA)
Arduino (GND) – Dexter (GND)
Arduino (USB) – PC (USB) [for the power]
- Block on labView:
Import is ok, the compilation is ok for “read 1 Byte” mode, “write 1 Byte” mode and other modes but for “Read ascii" mode the ev3 compiler writes "Unable to compile some documents for deployment: prova.ev3p: Use of a block which no longer exists."
3: I used first your example then I added a few lines of code to control it as Serial.print(Wire.available()) in Loop() module or Serial.print(“ciao”) in sendData() to test if wire.availabe() was >0 and if it ran sendData().
Arduino’s Serial monitor always answered 0 for wire.available() and never wrote “ciao”.
- Pullup buttons on Dexter interface are both high,i.e. button 1 is near the 9 of 219 and button 2 is near the 2 of 522.
