This is a major change to how the main tick interrupt is handled on the mc1322x platforms. Instead of using two timer resources, TMR0 and RTC, this patch unifies all the timers to use the RTC. This is enabled by implementing etimers as scheduled rtimers. The main advantage (aside from freeing TMR0 for general use) is have the Contiki timebase come from the same source that will be used for sleeping and wakeup. |

libmc1322x is a library, build system, test code, and utilities for using the mc13224v from Freescale. Getting Started --------------- $ cd tests $ make this will build all the test files in libmc1322x/tests for each board defined in libmc1322x/board. You will have programs like: rftest-tx_redbee-dev.bin rftest-tx_redbee-r1.bin rftest-rx_redbee-dev.bin rftest-rx_redbee-r1.bin if you only wanted to build binaries for one board you can do: $ make BOARD=redbee-dev You can use mc1322x-load.pl in libmc1322x/tools to run your code: $ ../tools/mc1322x-load.pl -f rftest-tx_redbee-dev.bin Incorporating libmc1322x into your own code ------------------------------------------- The best way to incorporate libmc1322x into your code is as a git submodule: $ mkdir newproject $ cd newproject $ git init Initialized empty Git repository in /home/malvira/newproject/.git/ $ git submodule add git://git.devl.org/git/malvira/libmc1322x.git This will add libmc1322x to your repository. Now to setup the Makefile: $ cp libmc1322x/tests/Makefile . You need to edit the Makefile to point MC1322X to your libmc1322x submodule: Change line 1 MC1322X := .. to MC1322X := libmc1322x and edit COBJS and TARGETS accordings. COBJS are all of your common code for any of your programs. TARGETS are the names of your programs. For instance, you can have a common routine that prints a welcome message that is used by two programs a and b. You would add common.o to COBJS: COBJS:= common.o and your target line would read: TARGETS := a b COBJS are made for each board --- so it is ok to have board specific code in there. As an example, tests uses this in tests.c to print the name of the board in the welcome message. You could also use this to change your GPIO mappings between boards.
