Introduction: 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
Attachments
Step 1: Wiring
SCL || 15 (or SCLK)
SDA || 16 (or MOSI)
RES || 8
DC || 9
CS || 10
BL || +5V (Optional)
Step 2: Program It
Notice: the Adafruit related library needs to be installed via Library Manager.
Step 3: My Sharing
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!!!
