ST7735 1.8″ TFT Dispay: SPI vs General connection
I got a ST7735 based lcd from ebay and decided to play with it a bit.
- Arduino UNO
- 1.8″ TFT LCD from ebay
- Some jumper cables
Display driver library: https://github.com/adafruit/Adafruit-ST7735-Library
And the required graphics library: https://github.com/adafruit/Adafruit-GFX-Library
I am using the demo-sketches from the AdafruitST7735\examples\:
In the video you can see the communication protocol speed comparison.
SPI is the way to go 🙂
