Hempl

The PDF-able and printable collection for this book is at Wikibooks:Collections/Hempl. Hempl 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. Mizar32 thumb|right|The Mizar32 main board thumb|The Mizar32 Lisp machine running PicoLisp as its language 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.

Further reading 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. Lua Programming Lisp Programming Computing H 25%
