Recently I saw a development board from NVIDIA with a special discharge circuit, which uses a resistor and a MOS tube connected in series between the power supply and GND. When the power is turned off...
During the recent test, it was found that the data read by STM32 ADC using DMA mode would appear as follows
I started to suspect that it was high-frequency interference from external signals. After a ...
Why can't the P0 port of STC8A8K32S4A12 output a high level? The quasi-bidirectional IO port is set, and nothing is connected to the outside. When the low level is set, 0V is normal, and the high leve...
