Why can the 485 program only transmit single byte? The MCU is connected to the computer through a 232/485 converter and debugged with the serial port wizard. Can you see what the problem is?#includevo...
My program has some problems: Idea and code: Use TA0 as rising edge capture P1.1 as input terminal, use TB0 as timer, and when the time reaches 1s, use the number of rising edges captured by TA0 as fr...
Here's the thing. The program I made on ce4.2 had restrictions on edit input. The way to restrict it was to overload CEdit to CImputEdit class, overload OnChar in it, and change the definition of edit...
After understanding the previous few issues, I have achieved preliminary face detection
At the same time, the trial board has also expired...hahaI realized the collection and processing of face images...
Low power consumption has always been the most important feature of Zigbee technology, but in actual use, low power transparent transmission has always been a difficult point. When the terminal module...
