uLisp® is a version of the Lisp programming language specifically designed to run on microcontrollers with a limited amount of RAM. It currently supports the Arduino ATmega-based boards, Arduino ARM SAM/SAMD-based boards, Adafruit ARM SAMD51-based boards, BBC Micro Bit, and MSP430-based LaunchPad boards. You can use exactly the same uLisp program, irrespective of the platform.
Lisp is a flexible language, with many advanced features that make it easier to program in than C or C++, so it’s ideal for learning about fundamental programming concepts. It’s also an ideal language for expressing complex ideas, such as teaching a robot to solve mazes or finding the shortest route on a map.
Version 2.4 supports Adafruit’s M4 boards
The ARM version of uLisp now includes support for Adafruit’s M4 ATSAMD51-based series of boards: the Adafruit Metro M4, Adafruit ItsyBitsy M4, and Adafruit Feather M4. With 120MHz processors these are now the fastest platforms for running uLisp. For more information see Adafruit M4 Boards.
