Hello everybody,
I have a serious problem. I connected the ADPD188BIZ-S2 evaluation board according to the schematic of the user guide. The SDA line and SCL for I2C communication are connected to 4700 Ohm pull up resistors. When I connect the pins of the evaluation board with the respective GPIO pins of the micro controller used for I2C communication then SCL is pulled HIGH (3 V as expected) but the SDA line is pulled do 100 mV.
Can anyone tell me what I should try to figure out the problem.
I have already tested the jumper resistors for JP2 and JP4 and they are not short circuited.
Best regards,
Markus
