    Nokia 5110 LCD and Json Parser on ESP8266

    croutronics

      This is the best example i've found so far to work on the modules with GPIO broken out.

      It is simple bit banging of SPI, which gets around some of the issues using the HSPI port, and pin 15 being tied to ground, pullups etc.

       

      https://github.com/esp8266/Arduino                Arduino IDE for ESP8266 (actually compiles ESP code/firmware, using the ESP toolchain)

      Arduino Playground - PCD8544                     There is no library as such, just paste one of the examples

      https://github.com/bblanchon/ArduinoJson      Json parser library that compiles in the ESP version of the arduino IDE

       

      With those three, and the "WiFi Client" example, you have the basic building blocks to pull data (eg weather, bitcoin price, stocks) from the internet and display on a small device.
