In an electric bicycle, the inverter of the brushless DC motor consists of six power VDMOS tubes and six freewheeling diodes. The six freewheeling diodes are parasitic in these six VDMOS tubes, so the...
About using the emulator to adjust the STM32 program:When debugging the program in STM32 using JTLINK emulator (1) is it necessary to disconnect the power supply on the circuit board and use TVCC on J...
If I want to expand the serial port using 16c554, then if I use one interrupt for each serial port, the interrupt will be too wasteful. I saw on the Internet that it is possible to share an interrupt,...
