Yesterday, when I was debugging stm32, a wrong rom tablecomponent id error suddenly appeared when downloading the program. A dialog box popped up saying no cortex_m device found in jtag chain. I tried...
The input is 3.3V TTL high and low level. The Darlington output should be the opposite level of TTL. I checked and it is always in the same state. What's going on?Also, the PMOS at the back end is alw...
The 2407DSP interrupt system is divided into two levels. In the first level, there is a peripheral interrupt request register and a peripheral interrupt response register. The principle of the periphe...
