Use the PVD (threshold 2.9V) power-off detection function of STM32F101RC to save some data into 24C16! The phenomenon is like this: When I keep powering on and off the circuit, there is no problem sto
In the elevator industry, key switches are used in the control panel of the elevator car and the call panel installed on each floor. The keys are required to have high reliability, anti-interference,
The basic functions of inductance are filtering, oscillation, delay, trapping, etc. A more vivid way of saying it is : " passing DC and blocking AC " . In detail, it is in the circuit board, the induc
I want to save data (3 bytes) to EEPROM when power is off, and use BOD power-off detection, but I don't know how to use it. I hope experts can give me some advice:1. After setting BODEN and BODLEVEL i
