Based on a sample code for implementing the AGDI interface provided by Keil, I have a few questions for you! (1) //---------------------------------------------------------- //--- get a copy of all me...
As the title says, I recently used a logic analyzer (a pretty cheap one, but it doesn’t make sense that low-speed SPI would have problems, right?) to monitor the SPI communication between STM32F103C8T...
Xmodem protocol is one of the main ways of serial port data transmission. I am afraid only those who have worked on bootloader have the opportunity to use it. I have read the protocol online. The cont...
I am a beginner at STM32. Why can't I call functions after I use malloc to allocate less than 1K of memory? There is no problem when allocating. But when calling functions, it goes to the HardFaultExc...
