LISP Interpreter for ESP8266 Microcontroller

Implementations aspects of a fast+efficient lisp interpreter for an embedded IoT wifi computer device

ESP8266 is revolutionizing the IoT business, it's a 1-2 USD, one-chip computer, with built in Wifi, RAM (~90KB), GPIO, RS232, I2C, SPI, flash (4MB) on the size of 1cm x 2cm!

You can program it using C/Lua/python/javascript.

I found that Lua was too costly, so I embarked on implementing an efficient (storage+speed) lisp.

Agenda

1. esp8266 is what?
2. intro to lisp in X < 10 slides
3. simply lisp
4. eval/apply
5. functions
6. tail recursions optimizations (don't blow the stack)
7. saving bytes, bits, mallocs
8. storing data in 0 bytes!
9. lisp-machine/home-computer
