Can you analyze the logic of this schematic diagram? In the end, why can't I burn the program and perform simulation? How can the reset pin voltage of the MCU change from 3.3V to 2.8V?

Do you have analog ground and digital ground in your circuit?
Gabriel 發表於 December 17, 2020
This program upgrades and burns the circuit, and the reset circuit shares the ground. The analog ground is in another circuit.

If this is the case, will there be a voltage drop between the two power sources.
Carlos 發表於 December 17, 2020
If there is no problem with the circuit, the voltage will be reduced when the power supply is insufficient, which means that the load exceeds the capacity of the power supply.
