Re-ARM has been tested. AVR has not been tested.
1) moved all cpu specific items to files in the low level HAL directory
for that CPU (pinDebug_Re-ARM.h & pinsDebug_AVR_8_bit.h
2) added pinsDebug.h to the top level directory
3) modified HAL_pinsDebug.h to select the correct support file for the
selected CPU
4) Patched sanitycheck to stop throwing false errors. A long term
solution will be done
5) misc changes & bug fixes
arduino.cpp - included macros.h to fix a missing definition
pinmap_re-arm.h - removed a duplicated line.
pinmapping.h - changed from "ENABLED" to "defined" to fix a compile
error
======================================================================
split SanityCheck up, improve pinsDebug system
======================================================================
switch to latest pins_RAMPS_RE_ARM.h
