MSP340

Mecrisp is for MSP430xx chips and not for Cortex-M like Mecrisp-Stellaris, nevertheless they are both written by Matthias Koch and have many similarities as far as Forth is concerned, but the hardware is totally different. Both Mecrisp and Mecrisp Stellaris are hosted on the same site.

See: https://sourceforge.net/projects/mecrisp/files/ for downloads.

Svd2Mecrisp

Svd2mecrisp was created to take advantage of SVD files produced by Vadzim Dambrouski’s https://github.com/pftbest/msp430_svd which uses DSLITE files released by Ti and processes them with the Rust programming language.

Some features:- * Produces a Memory Map file you can upload via the Mecrisp serial terminal * Creates a Register-Reference file where you can copy and paste Bitfields you need into your program. Search this file using names from the Ti PDF’s for rapid location and use. * Includes helpful longer descriptions for Registers and Bitfields for less PDF reliance.

Download Svd2mecrisp HERE. Instructions are included along with a sample msp430g2553.svd.
