Espruino-on-ESP8266

This is a temporary project. A goal is to run the Espruino JavaScript (github.com/espruino) built with the Xtensa under esp-open-sdk (github.com/pfalcon/esp-open-sdk) directly on ESP8266 wifi module.

All the code changes for now are "dirty", source files and headers are all in ./user/. Once it pass the tests, we are going to contribute to Espruino repository.

Recent achievements:

• Upload and run main.js (flash memory address 0x60000)
• Evaluate JS code from serial port (115200 baud) and write to flash.
• GPIO functionality implemented.
• setTimeout & setInterval now work great (it came out as an issue - calling native function with 1 or 2 arguments)

To do:

• More hardware specifics: Add flash file system, other peripheries, then WiFi, DHCP, TCP/IP, socket, HTTP and then webSocket!

How to run Espruino on ESP8266?

esptool.py --port /dev/ttyUSB0 write_flash 0x00000 firmware/0x00000.bin 0x10000 firmware/0x10000.bin

How to upload & run JavaScript?

Customize your code in js/main.js and flash it:

esptool.py --port /dev/ttyUSB0 write_flash 0x60000 ./js/main.js

Example JavaScript:

'toggle GPIO2';

var gpio2 = new Pin(2);

gpio2.write(!gpio2.read());
