STM32G474RE PA3 PC5 Pin.

[ENGIN TANRIKULU]

Hello,
STM32G474RE is the processor model I use.
I read ADC from pin PA3 and I read IO from pin PC5. So whether these pins are common pins in the processor hardware? How can I separate these two pins from each other?

Hello @ENGIN TANRIKULU 

PA3 and PC5 are separate pins on the MCU. But on the NUCLEO-G474RE, both pin 37 and pin 6 of CN10 are connected to PC5. To connect the pin 37 to PA3, you should configure the solder bridge as described on the Table 11 of the UM2505. 

Best Regards.

hi,
I want to use ADC as pin 37 of CN10 and GPIO as pin 6 of CN10. I don't want there to be any connection between them. How can I?

To do that, you have to follow the Solder bridge configuration described in row 2 of the table 11 of the UM2505.

Best Regards.
