During the summer vacation, I went home and lay on the dam, looking up at the starry sky. Suddenly, I saw a shooting star passing by. There were also stars that were not moving. The children asked him...
STM32L476RG and STM32F405RG are both 64pin and basically compatible, so I tried to replace the STM32F405RG on PYBV10 with STM32L476. This way, not only can I use micropython, but also support low powe...
A memory checking routine is as follows: [code] for(i = 0; i < NUM_MEM_AREAS; i++) memory_map[i].used = 0; /* first write a 0 to all memory locations */ for(addr = MEM_START; addr < MEM_END; addr += P...
