Great Cow BASIC is an open-source BASIC compiler for 8 bit Microchip PIC and Atmel AVR microcontrollers. Also included in the project is Great Cow Graphical BASIC, an icon based editor for GCBASIC programs.
The latest release is June 2019. We are even closer to v1.00 release!!
We have added new capabilities that make Great Cow BASIC the easiest tool set available - supporting over 1000's microcontrollers with tools to make this fun and simple.
Please see the download section for your options. We have a Graphical IDE and textual IDE, we have just the compiler and we have a minimal install - it is your choice.
