How to replace MOSFET with bipolar transistors Generally speaking, bipolar transistors cannot directly replace MOSFETs because of their different control characteristics. MOSFETs are voltage-controlle...
Excuse me
1: Since there is GPIOx_IDR, what is the purpose of reading GPIOx_ODR?
2: GPIOx is configured as input. What are the functions of setting GPIOx_ODR and reading GPIOx_IDR?3: GPIOx is configur...
I was helping someone draw a board today and they asked me to convert it to a gerber file. After I converted it, why can't it be like the online tutorial? Why doesn't my file have a suffix? Please hel...
