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))
