Describes how to create a demonstration LED-toggling application on an Arm Cortex-M33 based PIC32CK GC microcontroller using MPLAB Harmony v3 modules configured with the MCC. The application toggles an LED on a timeout schedule and prints the toggling rate to a PC Serial Console. It uses PORT control, RTC for periodic sampling, EIC for switch-driven rate changes, and SERCOM USART plus DMA for serial output.

Creating the First Application on PIC32CK GC Microcontrollers Using MPLAB Harmony v3 with MPLAB Code Configurator (MCC) TB3358 Introduction MPLAB® Harmony v3 is a software development framework consisting of compatible and interoperable modules that include peripheral libraries (PLIBs), drivers, system services, middleware, and third-party libraries. The MPLAB Code Configurator (MCC) is a GUI-based tool that provides an easy way to enable and configure various MPLAB Harmony modules. The MCC is a plug-in to the MPLAB X Integrated Development Environment (IDE) . The PIC32CK GC family of microcontrollers (MCUs) designed with a 120 MHz Arm Cortex-M33 processor, providing a memory capacity of up to 2 MB Flash and 512 KB SRAM. Connectivity options include 10/100 Ethernet, Hi-Speed USB, Full-Speed USB, CAN FD and configurable serial communications. Analog support includes a peripheral touch controller with 32 channels and a 12-bit ADC with 3 Msps sampling rate. This document describes how to create a demonstration application on an Arm® Cortex®-M33 based PIC32CK GC microcontroller using the MCC with MPLAB Harmony v3 modules. The objective of this application is to toggle an LED on a timeout basis and print the LED toggling rate on the Serial Console. For this demonstration, the following MPLAB Harmony v3 modules are used and configured using the MCC: • One PORT pin to toggle the LED. • Real-Time Clock (RTC) PLIB to periodically sample LED toggling rate. • External Interrupt Controller (EIC) PLIB to change the toggling rate when there is a switch press event. • Serial Communication Interface (SERCOM configured as USART) and Direct Memory Access (DMA) PLIBs to print the LED toggling rate on a COM port terminal application (Serial Console) running on a PC. • PORT pins to communicate with the Serial Console (USART pins as they are responsible for printing the data on the Serial Console after receiving the values) .

FAQs

What is the goal of the demonstration application described in the document?

The application toggles an LED based on a timeout and prints the LED toggling rate to the Serial Console on a PC.

Which MPLAB Harmony v3 modules are configured using MCC for this demo?

It uses PORT for LED control, RTC PLIB for periodic sampling, EIC PLIB for switch-triggered rate changes, and SERCOM configured as USART plus DMA for serial output.

How does the document communicate the toggling rate to the PC?

SERCOM USART pins handle printing to the Serial Console after receiving values, with DMA PLIBs supporting data transfer to the COM port terminal application.
