Im trying to build a guitar pedal on a STM32F446RE. 'SoundIN' is assigned to a pointer that is assigned to address value of the adc samples. 'SoundOUT' is half of soundIN (Just a test to see if works). However, output pointer '*outPoint' is showing a...

Hello guys.I am using an nucleo-64 STM32f446RE development board and I am trying to sample a sine wave (532.2Hz/1.4Vpp) from a function generator. I am new to stm32 devices so I though I would use polling method for ADC, I know is usually the worse m...
