From 49fe0eec8f17698fc5f86d0abe01777af1fb2b23 Mon Sep 17 00:00:00 2001 From: Romain Forlot Date: Fri, 14 Apr 2017 13:24:07 +0200 Subject: Change directory architecture to use 2 separated projects. Each projects, binder and generator, has to be compiled separatly. CAN-binder will host high and low level binding CAN-config-generator only the generator used for low level binding. build.sh script just launch both build in their respective dir.
