I recently started experimenting with the DIP-28 version of the LPC1114 chip. It seems to be a great little chip with lots of features and value for its cost. I'm surprised that a community hasn't sprung up around it to support hobbyists.
Are there any forums or websites that focus on this chip and using it for maker style projects?
Being new to the NXP family of ARM chips I'm also confused about the various NXP official forums. LPCWare seems new so I joined this. But it seems the focus used to be the LPXpresso forum. So I joined that too. But it seems like they are trying to move to LPCWare but hit a bump so they didn't. So which one is the right place to post?
Could someone explain the role of LPCOpenware and how CMSIS fits into that scheme? Is the only why to get the latest CMSIS software for the LPC1114 via downloading the entire LPCOpenWare?

Ya you are right, i am also working on DIP since more than 7 years but there are no forums for my DIP LPC1114.
Let us create it .

Thanks Paul,
Is the intent of CMSIS to have the vendor provide the CMSIS implementation for the chip? I did find the standalone CMSIS code for download, but it seems that is version 2.0 and the one in LPCOpen is version 3.0. I'm using open source tools and want to avoid any kind of licensing restrictions. It looks like the CMSIS code is free of any restrictions even in the LPCOpen version. Is this a valid assumption?
I've been chronicling about my successes on a site totally unrelated to NXP chips. I'd prefer to write it someplace where someone else might actually care : ) Here is what I have so far. Some might find the code to drive ws2811 chips useful.

Hi Rick
I am not familiar with a community supporting the 28-pin DIP version of the LPC1114. There may be one, but I haven't seen it.
LPCware is the preferred location to get documentation and software for the LPC family of microcontrollers. The LPCXpresso forum was created for support of the LPCXpresso tools. NXP monitors both the LPCware and LPCXpresso forums. The LPCWare and LPCXpresso forums will hopefully merge, especially now that NXP has acquired Code Red.
The goal of LPCOpen is to allow users to "Access NXP microcontroller software libraries all in one place. The LPCOpen Platform allows users to quickly and easily utilize NXP's extensive array of microcontroller software libraries to create and develop multifunctional products. The platform uses common APIs that work equally across all microcontroller families and can be built with Keil, IAR, and LPCXpresso (Eclipse-based tool from Code Red) tool chains. Detailed documentation and examples make it easy to integrate the necessary development tools into projects."
It would be best to visit the ARM website to get details regarding the CMSIS (Cortex Microcontroller Software Interface Standard). You will find information related to CMSIS at:

In addition to LPCOpen, we still provide example code for the LPC microcontrollers. The example code for the LPC1114 can be downloaded from:
