After writing the point-to-point communication, the terminal sends the "LED" character to the coordinator, and the L2 light of the coordinator is on, and then the L2 light of the terminal is on, and t...
Control idea: Press the MCU button K3, the LED can be controlled by the host computer (replaced by the serial port debugging software); release the MCU button K3, LED1 can be controlled by the MCU K1 ...
I used two of them, and both broke after writing more than ten times. They also didn't work after being unlocked successfully. Maybe the flash was really broken.I would like to make a statistics here....
What is the main function of the power line filter, what are the main parameters to consider when selecting it, and what issues should be paid attention to when using the power line filter?
