What is the reason why ESP-32 can still work after the capacitor of the crystal oscillator is shorted by the ESP-32 hard
In normal operation, the software control chip outputs a high and low level signal with a frequency of 100HZ at GPIO5. When we short-circuit the load capacitance of the 40MHz crystal oscillator, the output signal of GPIO5 changes to a signal of 10HZ-20HZ, and the CPU seems to be working at reduced f...
