I'm extremely new to all of this. My goal is to connect 2 to 4 accelerators to a STM32F3DISCOVERY and record an event based on the rising edge of a signal. Any direction on this is much appreciated.

I picked the STM32F3 Discovery board because it has 4 ADCs that can supposedly record data at 5MSPS. I am new so a little direction on example code and which pins to use would be great. Im currently trying to be more familiar with the STM32CubeIDE...
