[size=4]When learning about current source and voltage source, the question about the internal resistance of the power supply often confuses many people. They only remember that when the voltage sourc
Due to PCB size limitations, I want to use STLINK's SWD method. There are generally three versions online:(1) SWDCK (TCK), SWDIO (TMS), GND, nSYSRST, VCC(2) SWDCK (TCK), SWDIO (TMS), GND, nSYSRST(3) S

Hi, I want to use the USB interface function of a stm32F405, but I want to use its high speed mode, that is, the faster the better (theoretically 480MHz). I want to ask, who has used this solution bef
There was a time when microprocessors (MPUs) and microcontrollers (MCUs) were two completely different devices. Microcontrollers completed "control" related tasks and responded to external signal stim
