Arduino Micro Connect to ST7735 Display
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
Downloads
Wiring
SCL || 15 (or SCLK)
SDA || 16 (or MOSI)
RES || 8
DC || 9
CS || 10
BL || +5V (Optional)
Program It
Notice: the Adafruit related library needs to be installed via Library Manager.

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!!!
