raspiezo / Nucleo_L432KC_Quadrature_Decoder_with_ADC_and_DAC

A program to monitor some parameters for a motor

Dependencies:   mbed-dev BufferSerial

Thanks to David Lowe for https://developer.mbed.org/users/gregeric/code/Nucleo_Hello_Encoder/ which I adapted for the use of TIM2 32bit timer as an encoder reader on the Nucleo L432KC board.
