I have seen many people on the Internet use CPLD and DM642 to control TL16C752B to achieve serial communication with PC. But what confuses me is that there is no one on the Internet who uses DM642 alo...
I am debugging a NB module, which has an RS232 interface. I can debug it on the computer by using a USB to 232 cable. I also made a CH341T circuit and want to use 430 to send AT commands. The schemati...
Impedance actually refers to the parameters of resistance and reactance. Because the PCB circuit (bottom of the board) needs to consider the installation of electronic components, and the conductivity...
I need to modify the UI interface of TCPMP, preferably like WMP or other software with skins. I want to modify it in X86 first, and then in WINCE. Now I can build the exe file in X86. I can modify the...
