1. What is the inverted state of a transistor? When the collector junction is forward biased and the emitter junction is reverse biased, it is an inverted state; when the collector junction is forward...
When porting from CH32F103 to CH32V103, the original program has IAP. After switching to RISC-V, I don't know how to convert the instructions. The main questions are:
1. In the ld file, the ROM start ...
What a talent! The test result of the pegboard: in a normal office environment, the communication distance with the mobile phone is up to 30 meters.
The antenna is a solder wire of about 31mm, which i...
1. Input voltage is too high
The input parameter of the power module is abnormal - the input voltage is too high. This abnormality can cause the system to not work properly, or even burn the circuit. ...
The operating voltage of RS-485 transceiver is low (about 5V), and its withstand voltage is also very low (-7V~+12V). Once overvoltage is introduced, it will break down and be damaged. When there is s...
Compound voltage overcurrent protection, it is a voltage compound element composed of a negative sequence voltage relay and a low voltage relay connected to the phase voltage. As long as one of the tw...
