Fork of FastIO by Erik -

FastIO.h@15:e0c5a5216647, 2015-07-09 (annotated)

Committer:
Sissors
Date:
Thu Jul 09 21:11:39 2015 +0000
Revision:
15:e0c5a5216647
Parent:
13:0e21ffc6cb84
Child:
18:c95920122b2e
Initial EFM32 support. FastIn and FastOut child classes seem to be broken yet again. EFM32 has broken mode switching (don't blame me for their GPIO being a pain to use).
