Hi,
I ma trying to connect Analog 07 to circuit that I have. I know that the analog 07 maps to P18.7 on the smartRF05EB board. I already removed the jumper that connects the POT to that pin.
I notice that analog PIN is set to 3.3v when nothing is connected to it. This is a huge problem for my circuit. Is there anyway to stop the PIN from presenting 3.3v. I am using the HAL_ADC library to read the ADC pin value. The library works because if I connect to pin to ground or 3.3v it gives the correct value in the software. But I am connecting the PIN to a circuit I built and if the PIN is driving 3.3v then it will cause my circuit problems. I need to pin to be at 0v.
Is this even possible?
