#5 NodeMCU/ ESp8266 Tutorial: ST7735 LCD with Adafruit Library

In this video I explain how to connect an ST7735 LCD with esp8266 and use Adafruit GFX library.
The Pin Connection:
LCD ESP8266
VCC 3.3V
GND GND
CS D8
Reset 3.3v
A0 or D/C D4
SDA (MOSI) D7
SCK D5
LED 3.3V
The libraries are:
Adafruit GFX library: github.com/adafruit/Adafruit-...
St7735 LCD library: github.com/adafruit/Adafruit-...

Awesome tutorial ! Simple and direct !!! I really appreciate your video.

[@RadekMarszalek]

That works for me! THANKS A LOT!

[@geniustechnology3358]

Today i subscribed your channel for your good videos and information. So keep it up

[@ataurrahman-zu5pr]

Today I subscribed your channel for you very good videos. So keep it up.

Do you also have other tutorial that teach how to draw graphic on this TFT display?

[@franciscolozano3801]

Hi! I see that you don't have any Arduino connected, are you executing it directily to the ESP8266? Thanks!

[@MohammedRezwanulIslam]

Yes

[@Jake4]

Not working for some reason, Using the same screen & device (Built fine and Serial console is outputting the correct text).

[@MohammedRezwanulIslam]

It worked for mr! Try a different lcd/ dev board.

[@tycstahX]

why aren't you selecting the libraries for install directly from the arduino ide library manager?

[@tycstahX]

Still thanks alot for the upload, it is very clear. Keep up the good work!

[@MohammedRezwanulIslam]

There are multiple ways to do a work. There is no wrong way as long as it works. This is my way......

error compiling for board nodeMCU 1.0 ............................
I have this problem, could you help me please

[@luexiong8496]

IT worked if we change:
#ifdef ADAFUIT_HALLOWING
#define TFT_CS 39
#define TFT_RST 37
#define TFT_DC 38
#define TFT_BACKLIGHT 7

My ST7735 screen is white

Me too...

[@nurhakimnor5748]

@@RayanTheTechnician I resolved mine. change your code for the output pin declarations

[@nurhakimnor5748]
