There is a 4-pin connector J11 for I2C communication in DLP4710EVM-G2.
How to use this connector? What's the function of each of the 4 pins?
I read in a solved thread that there shouldn't be any hardware modifications needed to the board to get communication working with Arduino.
I tried to use the following Arduino code (learned from another solved thread) to turn the LED on but didn't succeed.
#include <Wire.h> void setup() { Wire.begin(); Wire.beginTransmission(0x1B); Wire.write(0x52); Wire.write(0x02); Wire.endTransmission(); } void loop() { }
Is there anything else I need to do?
Many thanks in advance!
