About

Peter Mather (matherp on the Back Shed Forum) led the project, ported MMBasic to the Raspberry Pi Pico and wrote the drivers for its hardware features. The MMBasic interpreter and this manual was written by Geoff Graham ( http://geoffg.net ). In addition, many others have supported the project with specialised code, testing and suggestions.

Support

Support questions should be raised on the Back Shed forum ( http://www.thebackshed.com/forum/Microcontrollers ) where there are many enthusiastic MMBasic users who would be only too happy to help. The developers of the PicoMite firmware are also regulars on this forum.
