Understanding USART TX Pin Activity Using the Data Visualizer

Last modified by Microchip on 2026/10/23 09:33

Overview

In this video:

Using the data sheet to find the TX pin on Port D1
Using the Data Visualizer in Pin mode to monitor the activity on this line to see the pulse bursts every second
Using cursors to demonstrate that each transmission takes roughly 37 mS (spanning more than three timer counter-triggered Analog-to-Digital Converter (ADC) sample readings and ADC conversion complete Interrupt Requests (IRQs))
