Hempl is recursive for Hempl's embedded mini PicoLisp.
It is a software system for natively programming microcontrollers (interactively and incrementally) using PicoLisp.
Hempl can read S-expressions from a micro SD card or from the console (over UART, USB or Telnet).
Hempl is influenced by and is a fork of the eLua project.
This manual currently focuses on running Hempl on the Mizar32.
Congratulations! You have in your hands the manual for the Mizar32, a 32-bit computer based on the AVR32 processor at 66MHz with 32MB of main memory, mass storage on SD card, a USB connector, a light, two buttons, a JTAG port and six bus connectors. The bus connectors let you add other stackable hardware modules such as serial ports, ethernet, a 16x2 character LCD display and a VGA/keyboard/mouse/audio board based on the 8-core Propeller processor and your own custom boards.

If you would like to help complete this book, there is a list of stuff to do.
- Mizar32 is a book that focuses on the hardware; this "Hempl" book focuses more on developing software in the Hempl variant of Lisp.
- Alcor6L is a multi-language IDE for natively programming microcontrollers (interactively and incrementally), supporting (among other languages and hardware) PicoLisp on Mizar32. Alcor6L is a fork of the eLua project.
