[Qinheng RISC-V core CH582] serial port routine sending and receiving test [Copy link]

 

Tonight, I carefully studied the UART1 routine program and combined it with the data sheet. I felt that I didn’t understand it very well. I wanted to modify the read and write parameters based on the routine program to read infrared carbon dioxide data, but I really didn’t know how to modify the program. I also searched for two serial port evaluation articles shared by other netizens, but I didn’t understand them very well. I used to use TI’s UART routine program for modification, which felt relatively easy, but I don’t know how to modify Qinheng’s UART routine program for the time being. I hope there will be detailed introduction materials to facilitate secondary development. After all, my technical ability is limited, so I will take some time on the weekend to analyze the routine program and official materials. Although it is very difficult, I will continue to work on it. Today, I will use the UART1 routine program to burn into the development board, and then use the serial port assistant to send and receive data communications. The functional effect of the routine program has been initially achieved as shown in the figure below:

The next step is to focus on analyzing the serial port routine and try to modify the program so that it can successfully read the infrared carbon dioxide sensor data.

There are several posts that are very well written. If you believe me, you can also send me a private message. I feel that I am quite proficient in this serial port.

Ok, thank you boss!
