NodeMCU/BME280/SPI TFT/mqtt weather station

NodeMCU/BME280/320x240 TFT Weather station

Features

• integrated with IoTCC using mqtt
• display on SPI TFT LCD (ILI9341)
• NTP time sync
• debug on serial and LCD

WIP

• integration with PWS
• forcast via external webservice (based on pressure) due to low memory

SPI setup to connect display in func.lua

Initialize the matching driver for your display. All available are here http://nodemcu.readthedocs.io/en/master/en/modules/ucg/#display-drivers

disp = ucg.ili9341_18x240x320_hw_spi(cs, dc, res)

Connect TFT to NodeMCU

• Hardware SPI CLK -> D5 / GPIO14
• Hardware SPI MOSI -> D7 / GPIO13
• Hardware SPI MISO -> D6 / GPIO12 (not used)
• Hardware SPI /CS -> D8 / GPIO15 (not used)
• CS, D/C, and RES can be assigned freely to available GPIOs
