From a19a23ff92bffd2d32fa2c2c84026bdfd711c6ac Mon Sep 17 00:00:00 2001 From: "David A. Mellis" Date: Fri, 4 Mar 2011 21:05:05 -0500 Subject: Factoring pin definitions out of the core. That is, there's now a pins/ directory in a platform, which includes multiple directories, each of which has its own pins_arduino.h. The boards.txt gets a new preferences, .build.pins, whose values is a sub-directory of the pins/ directory (possibly with a "platform:" prefix). That sub-directory is then placed in the include path during compilation. --- pins/standard/pins_arduino.h | 199 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 199 insertions(+) create mode 100644 pins/standard/pins_arduino.h (limited to 'pins/standard/pins_arduino.h') diff --git a/pins/standard/pins_arduino.h b/pins/standard/pins_arduino.h new file mode 100644 index 0000000..8fabb17 --- /dev/null +++ b/pins/standard/pins_arduino.h @@ -0,0 +1,199 @@ +/* + pins_arduino.h - Pin definition functions for Arduino + Part of Arduino - http://www.arduino.cc/ + + Copyright (c) 2007 David A.
