Bill Brendling's MTXLib C Library

Introduction

In June 2022, a request was made on the Memotech Forum for someone to help

• create a library of C callable routines for writing programs for the Memotech MTX, with
• the ability to develop MTX programs without having to make extensive use of the command line and make files

Bill Brendling took up the challenge and created his MTXLib library of functions for SDCC and provided useful guidance on how to use it with a modern Integrated Development Environment (IDE). The thread on Memorum describes how to install the required components and get started using Bill's C library, you can post requests for help there - Bill is usually very quick to respond and helpful. Eventually, Bill will be posting his MTXLib(rary) to GitHub, but in the meantime (and going forward too), with Bill's permission, I have posted the library here.

Install all of the above, then download and unzip MTX_Projects.zip along with the MEMU version here and the Demo project.
