This file contains the STM32 project for creating a guitar tuner pedal.
Currently the pedal code is running on the STM32L432KC. Pin D3 is connected to the ADC. To read the pedal output open a serial tty terminal with a baud rate of 115200. The pedal will read signals in the range of 0-3.3V with frequencies ranging from 0-1000Hz.
