I have a question about the GPIO connection problem of I2C, PWM.

[schosdas]

Hello

PWM and I2C are being used on a custom board using nrf52832.
I connected I2C to pins 26 and 25 and PWM to pins 27.
But I2C doesn't work, and PWM does, but there's some noise.

The data sheet of the MDBT42Q (nrf52832) module shows the following.

Does this mean that I2C and PWM should not be connected to the corresponding GPIO pin?

Thank you.

Hi,

It's not recommended as they can interfere with the radio. They should work though. So your issue is probably related to something else. I'll close this case and we'll continue the discussion on the other thread , as it seems that this case is related that ticket.
