Hi,I'm trying to configure pin PC14 to be used as SDA signal as it stated in the datasheets STM32C031C6 and STM32C031G4: To configure the pin (and the the I2C) I am using: void SDK_I2C_Init(SDK_I2C_HandleTypeDef *hi2c) { LL_I2C_InitTypeDef I2...

I'm trying to write three functions: to start an ADC conversion, wait for it to complete, and retrieve the results based on the low-level drivers from ST. The issue I'm facing is that I can read the first channel (LL_ADC_CHANNEL_0) with the correct v...

Hey everyone, I just wanted to take a moment to say thank you for all the insights and suggestions!After hours of debugging, I finally got my I2C communication working with sensor. The issue? A hidden EXTI pin configuration buried in some project fil...

First of all, thank you all of you guys for pointing several things.It was really helpful to discover the pin PC14 in nucleo board is not connected, but I need to do some rework there to get it working, as pointed by @Andrew Neil . Since I have alrea...

By communication I mean reading data from the I2C device. When I configure other pins I see I2C peripheral working fine, but when I configure PC14, I see it is not working. But let me do a recap what I have seen until now.

Just checked, I see the value of FLASH_OPTR is 11111111111111111111111010101010, so I can see it is disabled, and still, there is no communication.

This does not really apply in the second board that I described, I see from the schematics those are 0 ohm resistors that need to be placed and removed to actually access to PC14 on the pin header and disconnect the LSE. On my second board, there is ...
