Contents of MSP430-Ada package:

doc			: Documentation. Currently contains a report on the project 
			  so far with detailed build instructions to reproduce it.
                          
                          Text file describing hwo to write and build an embedded application
			  using MSP430-Ada.

samples			: Sample code. Currently "hello.adb" (a null program used to 
			  test the compiler build process)

			Blinky folder
                          Several versions of the inevitable "Blinky" flashing LED demo.
			  blinky_naked.adb 	: written without the CPU support package.
			  blinky.adb 		: modified to demonstrate use of CPU support.
                          blinky_intrinsics	: modified to demonstrate compiler intrinsic 
						  functions for delay.
                          blinky_timer		: modified to demonstrate timer interrupts
			  (+ package timer_a)	  to generate delays
                          blinky_xtal		: As blinky_timer but with 32768Hz crystal
                          (+ package timer_x)     for RTC accuracy and LPM3 (< 1 ua sleep current)
                                                  Requires external 32768Hz crystal fitted to PCB.

			Watch folder
                          Watch is a LED digital watch, 1970's style, on a 33mm diameter PCB.
                          A basic digital watch which fits in a 1kbyte program memory.
			  Schematic and PCB layout are included in GEDA "gschem" and "PCB" format.

MSP430-mini-rts		: Bare bones RTS derived from the AVR-Ada project.

readme.txt		: this file.

cpu_support/cpus	: Ada packages representing every MSP430 CPU variant represented 
			  in the upstream C headers (from Texas Instruments).
			  "WITH" the appropriate package and you can use all the facilities 
			  and peripherals of that CPU portably (among MSP430 variants).

cpu_support/packages	: Ada packages representing every base CPU type and every variant
			  of every peripheral device found in the upstream C headers.
			  Do not use these directly. Instead, "WITH" the appropriate CPU 
			  package and it will select the correct packages from these.

cpu_support/gen_cpus	: Utility to build "cpus" and "packages". This uses GCLP
			  the Generic Command Line Parser from Launchpad.Net.
			  https://launchpad.net/gclp/1.0/1.0.0

gcc4.7.7_patches	: Patches to build MSP430_Ada over gcc4.7.2 and its other prerequisites.
