ST7735 TFT Library for Arduino environment

Postby Negativ3 » Fri Sep 15, 2017 11:28 am

Does this library exist?

I have the ESP32 DEVKIT V1.

The ST7735 TFT LCD I have says it's SPI however the pinout is:

RESET
A0
SDA
SCK
CS

Anyone can give me any pointers on this?
Thank you.

I'm currently searching for that library for ESP32 arduino.
To help you a bit more with that display:

RESET is reset
A0 is DC
SDA is MOSI
SCK is SCK
CS is CS

reset, DC and CS are passed in argument to object TFT with the arduino TFT library.

I found a library: https://github.com/Bodmer/TFT_eSPI
For me it seems to work well, faster that the Arduino TFT on a teensy3.2.
A bit hard coded, pins definitions are through #define in a .h, but I think it one of the reasons it run faster.

Also it support many display interface chips and displays.
