- Fri Jun 19, 2015 1:24 pm #20956 Heya,

can anyone show me how to connect TFT 1.8" LCD with ESP8266 ?
Preferably NodeMCU 0.9dev board markings.

I have one with pins noted - CS, SCK, SDA, A0, RESET.
I'm trying to use this library -> https://github.com/nzmichaelh/Adafruit-ST7735-Library .
According to pinout picture I can gather HSPICS and HSPICLK but have no idea where to connect A0 and/or RESET and
is SDA to HSPIQ or HSPID.

TIA,

after some reading managed to get it working, so for posterity here is documented pinout map ->

Code: Select all/*
 * ESP8266-12        HY-1.8 SPI
 * GPIO5             Pin 06 (RESET)
 * GPIO2             Pin 07 (A0)
 * GPIO13 (HSPID)    Pin 08 (SDA)
 * GPIO14 (HSPICLK)  Pin 09 (SCK)
 * GPIO15 (HSPICS)   Pin 10 (CS)
  */

#define TFT_PIN_CS   15
#define TFT_PIN_DC   2
#define TFT_PIN_RST  5

Adafruit_ST7735 tft = Adafruit_ST7735(TFT_PIN_CS, TFT_PIN_DC, TFT_PIN_RST);

What sort of things are you doing with the display?

currently it's DS18B20 graph, nothing fancy .. yet ..

Actually I'm going thru my arduino bin and connecting stuff to my latest toy ESP8266 ..
