Fix incorrect printf format specifier #337

Open szsam opened 4 months ago

szsam commented 4 months ago

PRI macros should be used for uintptr_t. Calling a printf-like function with the wrong type of arguments causes unpredictable behavior.

I am not sure if <inttypes.h> can be used on various embedded platforms, such as stm32 and other MCU SDKs. This requires some testing, and I will validate these platforms when I have time, so this pull request will be delayed. It would be even better if you could help with testing.
