This is an automated email from the git hooks/post-receive script.
fredrik at thulin.net pushed a commit to branch master
in repository user/ft/stm32-dev-bridge.
commit 9ad42067f92af1d717fecf355d429c2d381010a5
Author: Fredrik Thulin <fredrik at thulin.net>
Date: Wed Sep 2 16:42:14 2015 +0200
Import of Pavel's fmc-test application.
Copied here and slightly adapted to GCC build environment
(standard directory names and added Makefile).
Based on this commit:
commit 43b94a6ada83454c3404bda019ec114f97379c82
Author: Pavel V. Shatov <meisterpaul1 at yandex.ru>
Date: Thu Aug 27 00:01:24 2015 +0400
Initial version of FMC driver for STM32.
in the repository git.cryptech.is.:user/shatov/fmc-test.
