ssd1306-stm32HAL

ssd1306 library for stm32 using stm32-hal library's. This library works with i2c and is configured for 128x64 oled panels by default.

If you search 4-wire SPI support, you can find it in the afiskon/stm32-ssd1306 fork.

Usage

Compile and link the library files in your project.

- font.c 
- ssd1306.c

A full example for stm32f411 discovery is located in the example folder.

Small example:

#include "ssd1306.h"
#include "fonts.h"

I2C_HandleTypeDef hi2c1;

// Init lcd using one of the stm32HAL i2c typedefs
ssd1306_Init(&hi2c1);

// Write data to local screenbuffer
ssd1306_SetCursor(0, 36);
ssd1306_WriteString("4ilo", Font_11x18, White);

// Copy all data from local screenbuffer to the screen
ssd1306_UpdateScreen(&hi2c1);

128x32 example

The library can be used with different screen sizes by redefining the SSD1306_WIDTH and SSD_1306_HEIGHT defines. Some smaller screens might be wired with interlacing, if you encounter issues related to interlacing defining SSD1306_COM_LR_REMAP will configure the controller to support this feature.

make EXTRA_CFLAGS="-DSSD1306_HEIGHT=32 -DSSD1306_COM_LR_REMAP"
