es8266 ILI9341 LCD显示屏驱动测试代码





接线:
  • CS pin is connected to D2 (ESP8266EX GPIO4),
  • RST pin is connected to D3 (ESP8266EX GPIO0),
  • D/C pin is connected to D4 (ESP8266EX GPIO2),
  • MOSI pin is connected to D7 (ESP8266EX GPIO13),
  • SCK pin is connected to D5 (ESP8266EX GPIO14),
  • VCC and BL are connected to pin 3V3,
  • GND is connected to pin GND of the NodeMCU board.
