I am reading it in help files, variables declared as u16/u8 etc. What is this? Does it mean

u16=unsigned int type

u8=unsigned char type ?

The trouble with int, char, etc is that the 'C' language does not specify what size these types are - they are implementation defined.

That's why people create ''custom'' types of explicitly-defined size & signedness:

u16 - an unsinged 16-bit value;

s8 - a signed 8-bit value;

etc, etc,...
