This is a simple experimental Lisp compiler, written in uLisp, that will compile a Lisp function into RISC-V machine code. You can run the compiler on the RISC-V core of a Raspberry Pi Pico 2 (or another RP2350-based board):
The Lisp Badge is a self-contained computer with its own display and keyboard, based on an ATmega1284, that you can program in uLisp:
The RISC-V version of uLisp is designed to support microcontroller boards based on the RISC-V processor.
The RP2040 is a microcontroller chip designed by Raspberry Pi in the UK. It's a dual-core ARM Cortex M0+ running at 200 MHz which provides up to 16 MB of off-chip flash and 264 KB on-chip RAM. It has 30 GPIO pins, 4 of which can be used as analogue inputs, two UARTs, two SPI controllers, two I2C controllers, and 16…
This is a simple ray tracer written in uLisp, using the uLisp graphics extensions to plot on a colour TFT display. The scene contains five spheres and a plane and can be run on any of the following boards that include an integral TFT display:
