I made a control board with MSP430G2553, one TM1640 chip for display, two 595 for display and relay control, but it can't pass the group pulse test. When the group pulse is applied, the display is all...
I have a strange problem. If I assign a signal in the circuit to an output pin, the logic of the whole circuit is wrong. (If it is not output, the logic is correct when observed through other pins.) H...
The company uses a strapdown modem to transmit data, the terminal uses a 33600md, and the company headquarters uses a strapdown rack modem. The terminal modem automatically dials and establishes a con...
