AVR®: Understanding USART TX Pin Activity Using the Data Visualizer
In this video:
- The datasheet to find the TX pin on Port D1.
- The Data Visualizer in pin mode to monitor the activity on this line in order to see the pulse bursts every second.
- Cursors to demonstrate that each transmission takes roughly 37 mS (spanning more than three timer counter triggered ADC sample readings and ADC conversion complete IRQs).
