02.USART routines and tests [Copy link]

There is not much information about L233Cx Projects under the development board Demo, so USART is selected for testing.

Open the USART related program, compile and download it, and then burn it into the chip

Because I only have one Mini cable, after downloading the program, I moved the interface to the USART port and used the serial cable to power the board.

Open the serial port debugging assistant, set the baud rate to 115200, press the reset button, and you can see that the serial port assistant can successfully receive data.

At this time, we will receive the message and you can see the LED1-LED4 lights on and off in sequence.
