AVR®: Better Coding Practice for USART Send Using a Sendflag
In this video:
- Debug the IRQ driven USART communications to understand what happens when a string is sent.
- Demonstrate that the USART Data Rate Empty IRQ has hit a number.
- Create a global flag, which is checked in the while loop, to determine when the average should be sent over the USART, enabling us to move the USART send function out of the ADC ISR.
- Reveal that we still have the same functionality, but having implemented better coding practice.
