Arduino Micro Connect to ST7735 Display

Preview.jpg

When I browsing the internet for "Arduino connect to ST7735", most of them are talking about UNO. However, we should know that UNO and Micro has different pin out. But I just don't like UNO, it is too troublesome, i mean, TOO LARGE. So hope this tutorial would help you.

Supplies

You need:

Arduino Micro (of course!)

Some jumper wires (well, keep them jumping)

Breadboard (yes, you are hungry, for knowledge)

1.44' ST7735 LCD Display

CS || 10
BL || +5V (Optional)

Program It

It seems the SPI related pins are very important to set communication between the board and the display. At first I was copying the wiring method from some tutorials about "Arduino UNO conencts to lcd display", which does not work at all. So I search for the pin information for Arduino Micro, and figure out that the SPI pins are 14, 15 and 16. And lastly, light up your screen!!!
