I just got a chip. For commonly used chips, you can refer to the routines on the Internet for in-depth understanding. For an uncommon chip, the Datasheet is almost the only information for using the c

[size=4][b]Question[/b][/size] [size=4]How to consider electromagnetic compatibility (EMC/EMI) when designing PCB? What specific aspects should be considered? What measures should be taken? [/size]
I connected the red test lead to pin 46 (the pin that generates PWM) and the black test lead to gnd on the board, but the oscilloscope did not display a waveform and the PWM indicator light was flashi
