This guide shows you how to connect the Graphic ST7565 Positive LCD (128x64) from Adafruit to the Raspberry Pi (1 or 2) and control it with Python. The provided script is very simple and works as a proof of concept.
I created this guide because I could not find a complete guide how to use the ST7565 with python.
- Solder wires to the LCD
- Connect the wires with the Raspberry Pi:
| LCD Pin | Raspberry Pi Pin Name (GPIO.BCM) | Raspberry Pi Pin Number |
|---|---|---|
| CS | BCM 2 | 3 |
| RST | BCM 3 | 5 |
| A0 | BCM 4 | 7 |
| CLK | BCM 27 | 13 |
| SI | BCM 17 | 11 |
| VDD | 3.3V | 1 |
| GND | GND | 6 |
| R- | (not tested) | |
| A+ | 3.3V | 1 |
| G- | (not tested) | |
| B- | (not tested) |
See the position of the Pins at http://pinout.xyz/.
The Raspbian operating system provides the required python binary and the [Rpi.GPIO Module] (https://sourceforge.net/projects/raspberry-gpio-python/).
Copy the python file display.py to the Raspberry Pi and run it. Extend the script. It is very simple and just a proof of work. The script is based on the Forum discussion at https://www.raspberrypi.org/forums/viewtopic.php?f=32&t=25029
