I have for my project 8-Channel 12-Bit ADC for Raspberry Pi (STM32F030) and want to connect it to the old Raspberry Pi 1 B with cables (as this old RPi has shorter GPIO connector so I cannot connect it as a “Pi Hat”)
The Pi that I have and want to use with ADC:
The ADC - STM32F030:
Is it possible, does someone maybe know which GPIOs are used by STM32F030 to communicate with RPi? I couldnt find it in the documentation.
