The USB interface of STM32F103T6U6 seems to be easily damaged.Is it because of static electricity? Does the chip itself have a certain degree of self-protection?If not, what should be paid attention t
Actually, this function should have been implemented in yesterday's post, but I went astray. I always wanted to use the existing functions to implement it. After reading the posts of forum friends, I
Why can't I draw a manual wiring to another pad or cross it? When doing automatic layout, the flying wire of the transistor's 3rd pin has not been changed to the corresponding 123?
My test board uses pxa270 as the main chip, which requires a 13M and a 32.768K crystal oscillator. The current situation is that the two crystal oscillators have no waveform output. There is no proble
