_ARMPIN< PIN, _MASK, _PDOR, _PSOR, _PCOR, _PTOR, _PDIR, _PDDR > Class Template Reference

Template definition for teensy 3.0 style ARM pins, providing direct access to the various GPIO registers. Note that this uses the full port GPIO registers. In theory, in some way, bit-band register access -should- be faster, however I have found that something about the way gcc does register allocation results in the bit-band code being slower. It will need more fine tuning. More...
