The program is burned into the microcontroller, but it must be connected to the burner all the time [Copy link]

 

I want to ask. Since the program has been burned, why can't the program be executed when I unplug the burner? My understanding is that after burning, the power supply should not be turned off, right?

Uh, damn, it's OK. I guess I didn't react just now.

If the response is slow, check whether it is due to program design. Otherwise, check the reset circuit, local oscillator circuit and power supply.

Didn't react? Too fast?

That's not the case. I connected a wire to measure the battery voltage outside, converted the voltage into digital quantity and output it to the serial port connected to the pin. When I looked at the serial port information on my computer, there was no information. I thought it was not burned in.

Oh, it seems I connected it wrong.

Thanks
