== Summary ==
The 0.96-inch OLED module uses the SSD1315 driver, supports 4-wire SPI and I2C, has a 128×64 pixel resolution, and is powered via VCC at 3.3 V or 5 V.

== Technical overview ==
* Resolution: 128 × 64 pixels
* Driver IC: SSD1315
* Interfaces: 4-wire SPI and I2C
* Supply voltage: 3.3 V or 5 V at VCC; IO high-level voltage matches the supply voltage
* Housing dimensions: 26.0 mm × 26.0 mm; active display area: 21.74 mm × 11.18 mm
* Operating temperature: −20 °C to 70 °C; storage temperature: −30 °C to 80 °C
* Viewing angle: greater than 160°
* Color variants: Blue, White, Yellow/Blue (top quarter yellow area)
* I2C address selection via resistors R1/R2 on the back: R1 = 0 Ω for SPI, R2 unpopulated; R2 = 0 Ω gives I2C address 0x3C, R2 open gives 0x3D
* Raspberry Pi connection via 7-pin cable: DIN→MOSI/SDA (pin 19/3), CLK→SCLK/SCL (pin 23/5), CS→CE0 (pin 24), DC→pin 25, RES→pin 27
* For Raspberry Pi, the SPI or I2C interface must be enabled via “raspi-config → Interfacing Options”, then reboot
* Available libraries for Raspberry Pi: BCM2835, WiringPi, and lgpio; under Bookworm only lgpio is usable
* C demo invocation: “sudo ./main 0.96” in the “c” directory after compiling with “sudo make -j 8”
* Python demo invocation: “sudo python3 OLED_0in96_test.py” in the “python/example” directory

'''Commands and examples – verify before use:'''
<syntaxhighlight lang="text">
sudo raspi-config
sudo reboot
sudo make clean
sudo make -j 8
sudo ./main 0.96
sudo python3 OLED_0in96_test.py
</syntaxhighlight>

== Notes and version constraints ==
* The exact hardware configuration (R1/R2) depends on the desired interface; when switching to I2C, R2 must be populated or removed accordingly
* When using STM32, the I2C demo uses the analog I2C interface – wiring must be checked carefully
* Do not display the same screen for extended periods to avoid burn-in (residual images)
* Be careful with power polarity: do not reverse the power connection
* Under the Bookworm operating system, BCM2835 and WiringPi are unavailable; only lgpio works
* Compatibility with specific Raspberry Pi generations and kernel versions is not fully specified in the source
