waveshare-transparent-oled 1.0.1

Driver for Waveshare 1.51-inch Transparent OLED (128x64, blue) for Raspberry Pi

Note From the Developer

Waveshare didn’t ship any working Raspberry Pi code for this transparent OLED, and the few repos I found online were all Arduino-based or used custom microcontroller drivers. So I decided to build my own driver for Raspberry Pi fully in Python.

Why Python instead of C for a “firmware”-type project? Honestly… because I know Python best, and I wanted something fast to prototype, easy to extend, and beginner-friendly for anyone else trying to get this display working.

Also: The manufacturer’s wiring guide for Raspberry Pi was wrong, so getting this working required manually mapping pins, figuring out the correct SPI config, and reverse-engineering a stable init sequence. Hopefully this saves the next person a few hours (or days).

Everything else in this repo is handwritten, the only thing AI touched was sprucing up the README formatting.

Enjoy the driver. Hope it helps someone.

🟦 Waveshare 1.51" Transparent OLED Driver (Raspberry Pi)

A lightweight, Python-based driver for the Waveshare 1.51-inch Transparent OLED (128×64, Light Blue), designed specifically for the Raspberry Pi using SPI and CircuitPython GPIO.

This library provides:

✔ Simple .on(), .off(), .sleep(), .wake() controls ✔ Easy image rendering with Pillow ✔ Full-frame buffer support ✔ Clean hardware reset ✔ Example scripts (hello, clear, shapes, on/off) ✔ Raspberry Pi–compatible SPI initialization

🔌 Wiring (Raspberry Pi → OLED)

OLED Pin	Raspberry Pi Pin	GPIO
VCC	3.3V	—
GND	GND	—
D0 (SCLK)	Physical Pin 23	GPIO 11
D1 (MOSI)	Physical Pin 19	GPIO 10
DC	Physical Pin 18	GPIO 24
RST	Physical Pin 22	GPIO 25
CS	Physical Pin 24	GPIO 8

SPI must be enabled:

sudo raspi-config
Interfacing Options → SPI → Yes

🚀 Usage Example

Display “Hello OLED” in white on transparent background

from waveshare_transparent_oled import OLED_1in51
from PIL import Image, ImageDraw, ImageFont

disp = OLED_1in51()
disp.Init()

img = Image.new("1", (128, 64), "white")
draw = ImageDraw.Draw(img)

font = ImageFont.load_default()
draw.text((10, 25), "Hello OLED!", fill=0)

buf = disp.getbuffer(img)
disp.ShowImage(buf)

---

🟦 Turn Display On / Off

disp.on()     # Full power on
disp.off()    # Panel off

---

🌙 Sleep / Wake

disp.sleep()  # Low-power mode
disp.wake()   # Restore + turn on

---

🧽 Clear the display

disp.clear()

---

📁 Example Scripts

Inside the examples/ folder:

File	Description
hello.py	Static "Hello OLED" text
demo_shapes.py	Draw rectangle/circle test
on.py	Turn the screen ON
off.py	Turn the screen OFF
clear.py	Clear the panel

Run an example:

python3 examples/hello.py

🧠 How the Driver Works

• Uses SPI for fast frame updates
• Uses Pillow to generate a monochrome image
• Converts image → SSD1309-compatible buffer
• Sends 8 pages (128 bytes each) to the OLED
• Uses hardware reset for reliable startup

This driver is fully optimized for Raspberry Pi and avoids heavy overhead.
