This is my fourth post on the TI FR2xx microcontrollers that feature FRAM memory.  The links to the previous posts are at the bottom of this post.




I saw today where the MSP-EXP430FR2433 LaunchPad has been added to Energia, a modified version of the Wiring/Arduino IDE for select Texas Instruments microcontrollers and LaunchPads.




I have used Energia quite a bit in the past and most Arduino code and libraries will run on it, or at least port easily, provided they don't make direct register calls or use hardware specific to the microcontroller.  Energia runs on Windows, Linux, and MacOS.  To use the FR2433 with Energia make sure you are using the latest version and get the latest MSP430 core through the board manager in Energia.  Support for Energia is at


The FR2433 should run acceptably with Energia since it has adequate FRAM and RAM.  I updated and ran the blink sketch successfully but don't plan on doing much more with it in the near-term as the project I have in mind will use the FR2011 and I don't have the overhead to spare for Energia.
