I've attached an i2c current/voltage sensor on i2c1 on the lisa/m2, but it's not managing to get the values from it. I'm using v4.0 with TUDelft4.0
Debugging found that it's an acknowledgement failure immediately after the slave address is written to the bus.
Some article I found mentions the use of 10k pullup resistors to get i2c to work properly. Are these also required for lisa/m2? Has the i2c1 bus been tested with other devices and found working?
Other specifics:
- USE_I2C1 is defined - the sensor is working fine connected to an arduino - the master it's usually connected to doesn't send data, it just sends a request and then waits for the result
Any other things I can try?
Rdgs,
Gerard
