I have a question for you: I recently encountered a problem when debugging a program with 430f5438. When I used IAR simulation, I found that the program always ran away. The program in the interrupt c...
Hey guys, I want to use gprs dtu to transfer pictures and then display them on the computer. What knowledge do I need? What technology do I need? Can you give me some specific advice? Thank you very m...
STM32 independent watchdog ,
Driven by a dedicated low-speed clock (LSI), it can still be effective even if the main clock fails, so this watchdog can work under requirements unrelated to the main clo...
The code is as follows: Xxx_init(pvoid context) The calls are as follows: HKEY hkey=OpenDeviceKey((LPCTSTR)Context); RegQueryValueEx(hKey, REG_VAL_NAME, NULL, NULL, (LPBYTE)(&val_name), &dwDataSize); ...
