LPC1227 peripheral drivers are now available.


I’ve ported the drivers for this chip from Keil tools to LPCXpresso 7.6.2. Although they must be tested thoroughly, they look promising as well.

The project can be downloaded from here.

For now there is only a single example in the project, blinky. The plan is to add the standard examples from NXP for this chip, but I’ll do it later.

In LPCXpresso you can import this project as usual: In the Quickstart tab->Import project(s)->Project archive (zip)->Browse. Then browse the LPC1227_examples_0.1.zip file, and go on as with any other imported project. This is important that you select the three projects and choose the CMSISv2p00 library when you are asked for the CMSIS one.

The base projects CMSISv2p00_LPC12xx and Drivers_LPC1227 are compiled with the -Os flag because it’s not expected that the regular user debug them. The example project blinky is compiled with the -O0 flag. However you can change those flags to fulfill your needs any time. (An interesting fact: with the mentioned flags the code size for the blinky project is only 1500 bytes. If all flags are set to -O0 then the code size grows three times that figure: 4500 bytes).

The drivers’ documentation is found in: Drivers_LPC1227/Doc/lpc12xx.cmsis_.driver.library/LPC1200 Peripheral Drivers Library Manual.chm. This help file was generated with Doxygen with the internal source code documentation (already included as part of the Keil’s pack). However, in Linux there are not chm readers, so the plan is to create a doxyfile so each user can generate the documentation in html format. Meanwhile, if you’re a Linux geek you can get a chm reader through Wine, or better off you can create the doxyfile and share it!

I’m kind of active user in this forum so you can stop by from time to time.

If you find this project useful please drop me a line. And if errors are found please advice me. Any comment is welcomed.
