I have an AT switching power supply that needs to be repaired. The solution is TL494+LM339. The fault phenomenon is: the positive and negative 12V output is only more than 8V, and 5V is normal. I init...
The serial port and keyboard have two interrupts. The keyboard triggers the serial port to send data, and the display screen receives data. The two do not interfere with each other. But now when a key...
I use ULINK 2 to debug my own board (the connected JTAG signal lines are: JTAG_TDI, JTAG_TDO, JTAG_TCK, JTAG_TMS, JTAG_TRST connected signals). I started to think that the problem was that nreset was ...
