LPCOpen for LPC12XX

I was happy with my at-home-made board featuring the LPC1227 part, until I realised that there is not LPCOpen drivers for this family, so I needed to write my own plus getting some for here and some from there.

Does anyone knows why NXP hasn't released drivers for this family? Is there a problem with such a family? Is this a good idea to make a mass production with any of those parts?

Hello,

I started porting LPCOpen for LPC122x devices from the lpc_chip11cxx_lib library, I published it on GitHub.

Please note, that it is not yet tested, but the basic features of the MCU seem to work fine in my project.

Feel free to contribute.

Hi,

I've found drivers and examples for the LPC1227 chip in my old hard drive. It seems that those files have disapeared from the LPCWare site. Right now I don't have a way to share them, but for anyone interested I can send them to you by email, or if you have some sort of hosting I can publish them in there.

The files I've found are:

-- LPC1227_FreeRTOS7.0.3.zip
-- freertos_lpc1227.rar
-- FreeRTOS_7.0.1_ARM_CM0_portable_2011022.7z
-- LPC12xx-Xpresso samples.zip
-- CMSISv2p00_LPC12xx

OK, thats pretty obvious. Is there something like a migration guide from lpc12xx to lpc11xx? What are the differences in the peripherals, especially Clock, GPIO, UART, Timers and Flash/IAP?
The CMSIS device headers lpc1xxx.h are pretty different.

Hi OldManVimes,

It's been sad to realize that NXP is not taking into account this microcontroller family in its future plans, so it would be an excellent idea to drop the LPC1200 family out  from newer designs (I took a look to the link you posted).

By the way, LPCOpen support for the LPC1200 family does exist, but it's been hidden from the regular human being. Right now I'm not at the office, but ASAP I'll everyone interested on this issue show the location (it's been mixed with the LPC1100 family or so, I'm not shure at this very moment).

Cheers!!

That is a very hard question to answer definitively, because you cannot get a straight answer out of NXP support regarding things that might happen at some point in the future. But you can read between the lines. Have a look at this page: http://www.nxp.com/techzones/microcontrollers-techzone/longevity.html

It describes the longevity program for LPC parts. Notice anything missing?

Unless LPC support has some constructive feedback about this, you are welcome to draw your own conclusions about the LPC1200 family.

Regards,
Vimes

I'd really like to use lpcopen, but it only makes sense if I can use it in all my projects. We use 11xx, 13xx, 17xx, 18xx AND 12xx. Why is there no lpcopen for 12xx?

I don't believe there are plans currently for a version of LPCOpen for the LPC12xx family. However you can download peripheral drivers and examples for this family from:
