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.

Setting up PIC32MZ W1 Curiosity Board

  • Connect the J209 jumper of a temperature sensor
  • Connect the Debug USB port on the board to the computer using a micro USB cable
  • On the GPIO Header (J207), connect U1RX (PIN 13) and U1TX (PIN 23) to TX and RX pin of any USB to UART converter like USB UART click respectively

Running the Application

  1. Open the Terminal application (Ex.:Tera term) on the computer
  2. Connect to the “USB to UART” COM port and configure the serial settings as follows:
    • Baud : 115200
    • Data : 8 Bits
    • Parity : None
    • Stop : 1 Bit
    • Flow Control : None
  3. Build and Program the application project using its IDE
  4. Console displays the ADC count and the ADC input voltage
