Code Implementation
Serial Port Initialization:
Use uart_baud_set function when changing baud rate:
Serial Port Send Function:
Send data through the serial port based on the incoming data buffer and data length.
Interrupt Receive Function Handling:
Task Function:
Check if the circular queue is empty; if there is data in the queue, transmit it through the serial port.
Test Results
Serial Port Data Echo Successful:
Insights
Thank you to Lichuang for providing the testing opportunity; I learned about the usage of RA0 and Renesas MCUs. Using the Renesas FSP library and configuration tools significantly simplified the development process. I have mastered the functions related to opening the serial port, setting serial port parameters, reading, and writing data to the serial port.
