Also with the microchip PIC I was able to do everything I wanted just from reading the datasheet. Is there an equivalent for the SMT32 chips? Or do you just use libaries for everything?
''with the microchip PIC I was able to do everything I wanted just from reading the datasheet''
It is increasingly common these days that manufacturers (including ST) divide their technical product documentation between a ''datasheet'' and a ''user manual'' (specific names may very):
The ''datasheet'' contains only physical specifications - electrical, timing, mechanical dimensions, etc
The ''user manual'' contains details about operation, configuration, registers, etc.
A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
