MM32F031 Development Board Evaluation 4: UART and ADC Test [Copy link]

I originally wanted to test the UART first, and then open the ADC routine to display the AD converted data through the serial port. But when I opened the ADC routine, there was already UART output. Since there was no adjustable resistor (three pins ground), I bought one on the street. It doesn't look too ugly and is green. I tinkered with it, soldered it to the PCB, and then connected a wire from P3 to A1 (according to the first channel) The picture is as follows: According to the schematic diagram: It is not connected to any pins but just an external socket. I directly soldered a Dupont line male wire to the socket, and connected the other end of the female wire to A1. The following is a screenshot of the UART test: The following is a screenshot of the ADC routine test: From the test here, you can see that the ADC is very accurate. I checked the data sheet and found that the ADC is a 12-bit ADC. After reviewing this, I feel that this chip will be popular. This content was originally created by EEWORLD forum user ddllxxrr.

The test shows that the ADC is very accurate. I checked the data sheet and found that the ADC is a 12-bit ADC. After testing this, I have a vague feeling that this chip will be popular.
