This is a diagram I drew in PROTEUS. Ports D7 and D1 are used for both row and column lines. Since the column line circuit is at a high level, I think the row scanning method should be used. But how t...
I have a question: I use a PC104 COM+422 converter to send data to a device, but the device does not respond. I use the PC COM+422 converter to send data to the device using a serial port debugger, an...
I have always been confused about several concepts. What is the relationship between DDR, DDRC, and DDR phy? Especially what is the phy (physical layer) specifically? There seem to be many such, such ...
The board I made has a common problem. I can't get into CCS. I have only tried it twice, and it's related to the machine. I can't get into my own machine. I changed two machines and tried to get into ...
I am currently completing a project, which is due on the 19th. I am not familiar with many chips, so I hope you can give me some advice. Thank you very much!...
I know it is almost an impossible task, as I have never done any hardware-related development. After so many years of PC upper-level application development, today I encountered a project that require...
