Getting Started Using MPLAB® Harmony in VS Code® (for PIC32C and SAM Development) Playlist: https://youtube.com/playlist?list=PLtQdQmNK_0DTGNRV0qKkIEFn2fmrN0q31&si=K9Z9WB0hkz-LrlSh Building on where we were at the end of the 100 ms Timer video, a SERCOM (Serial Communications Interface) peripheral is now added to the project, which can be configured as USART, SPI or I2C. Here the SERCOM is configured as a UART. 1. A low level, hardware specific function, is used to send "Hello World!", i.e., SERCOM1_USART_Write( ). 2. Then a STDIO binding is added, allowing standard printf, with a count variable. 3. Finally, a USART loopback is implemented, using the context help code snippet. In between, the MPLAB AI Coding Assistant is used, to lend a hand here and there. In closing, the SYS_CONSOLE is introduced, which offers similar functionality.
