ADCHS polling
This example application shows how to sample an analog input using the ADCHS peripheral and displays the converted samples on a serial terminal.
Description
In this application, an analog input is converted by a hardware trigger generated by the TMR peripheral. Converted digital value is displayed on the serial terminal.
