I have a question about LidarTestingUtility. #23

Hello, there was no pulse in my previous TDC. At that time, the request of the program was correct. Now TDC has a pulse and it becomes N/A. Does this mean that my single chip microcomputer is broken?

Hello. Is MCU flashed with right firmware? Check your UART connections. Check that MCU quartz oscillator is soldered well, wires from quartz to MCU is OK. Do LED blinking? How fast?

pikasm commented 7 months ago

I tested the frequency of LED. It's 5HZ.

Here are my test results. 微信图片_20231120182430

Should I check if there is something wrong with MCU next? But my TDC pulse is correct, DA6 also has pulses, J2 also has pulses. Should I reinstall a DD2?

Maybe it is really something wrong with MCU, but It is strange that other functions are working, and UART is not working. Try to check soldering MCU pins 39/40. You can check with an oscilloscope MCU RX/TX lines when PC is sending requests.

Then I'll check it. Thank you.

I replaced the single chip microcomputer and got a signal. Thank you so much. I am so happy.
