The beginning of fun with powerful ESP8266 ESP-12E nodemcu 1.0 Wifi dev kit.
- Programming IDE - esplorer available at http://esp8266.ru/esplorer/
- Final sketch-code to display sample electromania text is available on GitHub page here
- Graphics library U8glib available at-https://github.com/nodemcu/nodemcu-firmware/tree/master/lua_examples/u8glib
- Followed pin out guidelines from- https://github.com/nodemcu/nodemcu-firmware
Pin connections between ESP8266-12E and SPI OLED display
-- D3 pin of ESP to RES pin of Display-- D4 pin of ESP to DC pin of Display
-- D5 pin of ESP to SCL pin of Display Hardware SPI CLK = GPIO14
-- D7 pin of ESP to SDA pin of Display Hardware SPI MOSI = GPIO13
--** Same pin out can be used to run the default U8Glib library graphics code available here.
Display- 0.96 inch 4 pin SPI OLED display with 64x128 resolution
Note- I dont get any royalty from banggood for these projects, I mention this because it makes easy for you all to understand exactly which make electronic device I am using and how to make it work :). I noticed every make has different pin markings.
