Just wondering if there is any API function that print information about the internal RAM, like how much free space left for example.

P.S.
xPortGetFreeHeapSize - > Gives information about the overall Memory space including external RAM .

Thanks

The heap allocator has a bunch of functions to query memory usage, maybe those do what you want.

heap_caps_get_free_size(MALLOC_CAP_INTERNAL)
