解释u32 {aka volatile long unsigned int}的类型含义: u32是一个无符号的32位整数类型,等同于unsigned long int。而volatile关键字表示该变量可能会被程序之外的某些因素(如硬件)所修改,编译器在处理这个变量时需要特别小心,不要对其进行优化。 提出解决方案,如何正确地将u32类型转换为int类型以供%d使用: 由于%d...

ext/hal/cmsis/Include/core_cm7.h:2453:22: note: expected ‘uint32_t * {aka long unsigned int *}’ but argument is of type ‘u32_t * {aka unsigned int *}’ So the typedefs are obviously different. Thank you for all your insights!
