After the PADS PCB file is converted to ASC, and then the ASC file is imported into AD, why is the PCB copper plating imported into AD gone, and the pads connected to the ground become disconnected? H...
I use STM32F107VCT6 to write a program, and use wind direction and wind speed sensors. They are all 485 interfaces, connected to the same 485. But the data is accurate when only one sensor is connecte...
After creating a socket in the vxworks operating system, use rc=connectwithtimeout (5 seconds). If rc==error is returned, the socket connection is closed. However, each time close is called, -1 is alw...
I have received the SLN-RPK-NODE kit for a few days. I have never successfully logged into the official APP. The problem of APP is easy to solve. At worst, I can write one myself. The routine program ...
