lispBM (LBM)
LispBM is a lisp or scheme like programming language for microcontrollers. LispBM also borrows a couple of ideas from Erlang when it comes to concurrency, message passing, pattern matching and process monitoring. The LispBM runtime system can be compiled for either 32 or 64 bit platforms and runs on a wide range of hardware such as for example STM32, NRF52, ESP32 or X86. When running the LispBM runtime system on a microcontroller it can be built on top of ChibiOS, FreeRTOS or ZephyrOS or, if you are adventurous, on bare-metal. LispBM can also be built to run on topof a regular linux.
The LispBM mascot, Lispy the llama, was created by PixiLadyArt. Thank you, Pixi!
Want to get involved and help out?
There are lots of interesting things to code on in and around the LispBM runtime system.
- Are you interested in microcontrollers and programming languages?
- You find it fun to mess around in C code with close to zero comments?
- Then join in the fun. Lots to do, so little time!
- Poke me by mail bo(dot)joel(dot)svensson(whirly-a)gmail(dot)com.
Documentation
- Work in progress LispBM language reference.
- Work in progress LispBM programming manual
- C code documentation can be found here.
- LispBM's internals are documented as a series of blog posts.
- There are demonstrations on YouTube.
Features
- heap consisting of cons-cells with mark and sweep garbage collection.
- Built-in functions: cons, car, cdr, eval, list, +, -, >, <, = and more.
- Some special forms: Lambdas, closures, lets (letrecs), define and quote.
- 28-Bit signed/unsigned integers and boxed 32-Bit Float, 32-Bit signed/unsigned values.
- Arrays (in progress), string is an array.
- Quasiquotation.
- Concurrency.
- Message-passing.
- Pattern-matching.
Vague or continuosly ongoing todos
- Doxygen?
- Tutorials?
- Be much more stringent on checking of error conditions etc.
- Make uniform how to return success or failure. It is sometimes bool and sometimes int right now.
Compile a 64bit binary for linux
-
Build the repl:
cd repland thenmake all64 -
Run the repl:
./repl
Compile a 32bit binary for linux (Requires 32bit libraries. May need something like "multilib" on a 64bit linux)
-
Build the repl:
cd repland thenmake -
Run the repl:
./repl
Compile on Raspberry Pi
To build the library exeute the following command in the lispbm folder:
PLATFORM=pi make
To build the repl example repl do:
cd repl
make pirepl
Then start it up using ./repl
Building the library is not a prerequisite for building the repl anymore.
SDL and LispBM
In the sdlrepl directory there is a start of a set of SDL bindings for LispBM.
To build this repl you need the following dependencies:
- libsdl2-dev -
sudo apt-get install libsdl2-dev - libsdl2-image-dev -
sudo apt-get install libsdl2-image-dev
Then compile the repl using the command make
