[size=4][color=#0000ff]Note: Be sure to disconnect PL2303 during debugging, otherwise the MCU power-on reset will not be normal. At first I thought it was a program problem, but later RS3232 became no...
When my PC is connected to the PLC, the PLC prompts: the connection is not feasible, the PLC is "read-only". I think it is encrypted, but there is no prompt to enter the password. The PC and PLC canno...
The author of XBoot mentioned that QG2101 is a re-skin of V831. This camera has an Ethernet port and may be a good choice for use as a development board.

I am a driver novice. Some time ago, I used VC to read and write I/O. In the process of I/O reading and writing, I first had to load the driver file (.sys), so I thought about how to write a driver fi...
The silk screen on the back is a little small, you can enlarge it yourself. A 24c02 is drawn on the board. If r4 and r5 are disconnected, R1 and R2 are pull-up resistors.[b][color=#5E7384]This content...
The program compiles without errors or warnings. The problem is that the data read from different registers appear to be the same. I don't know which part is wrong, the read or the write? Here is the ...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
