LibDriver SSD1306

MISRA API License

SSD1306 is a single-chip CMOS OLED/PLED driver with controller for organic / polymer light emitting diode dot-matrix graphic display system. It consists of 128 segments and 64 commons. This IC is designed for Common Cathode type OLED panel.The SSD1306 embeds with contrast control, display RAM and oscillator, which reduces the number of external components and power consumption. It has 256-step brightness control. Data/Commands are sent from general MCU through the hardware selectable 6800/8000 series compatible Parallel Interface, I2C interface or Serial Peripheral Interface. It is suitable for many compact portable applications, such as mobile phone sub-display, MP3 player and calculator, etc.

LibDriver SSD1306 is the full function driver of SSD1306 launched by LibDriver.It provides the functions of drawing single point, filling block, image display, etc. LibDriver is MISRA compliant.

Install

Reference /interface IIC, SPI platform independent template and finish your platform IIC, SPI driver.

Add the /src directory, the interface driver for your platform, and your own drivers to your project, if you want to use the default example drivers, add the /example directory to your project.

Usage

You can refer to the examples in the /example directory to complete your own driver. If you want to use the default programming examples, here's how to use them.

example basic

#include "driver_ssd1306_basic.h"

uint8_t res;

res = ssd1306_basic_init(SSD1306_INTERFACE_IIC, SSD1306_ADDR_SA0_0);
if (res != 0)
{
    return 1;
}

...

res = ssd1306_basic_clear();
if (res != 0)
{
    ssd1306_interface_debug_print("ssd1306: clear screen failed.\n");
    (void)ssd1306_basic_deinit();

    return 1;
}
res = ssd1306_basic_string(0, 0, "123", 3, 1, SSD1306_FONT_16);
if (res != 0)
{
    ssd1306_interface_debug_print("ssd1306: show string failed.\n");
    (void)ssd1306_basic_deinit();

    return 1;
}

...

res = ssd1306_basic_rect(0, 31, 31, 31, 1);
if (res != 0)
{
    (void)ssd1306_basic_deinit();

    return 1;
}    

...

(void)ssd1306_basic_deinit();

return 0;

example advance

The image extraction format is as follows and every pixel stored in one byte.

#include "driver_ssd1306_advance.h"

uint8_t res;
uint8_t image[8192];

res = ssd1306_advance_init(SSD1306_INTERFACE_IIC, SSD1306_ADDR_SA0_0);
if (res != 0)
{
    return 1;
}

...

res = ssd1306_advance_clear();
if (res != 0)
{
    ssd1306_interface_debug_print("ssd1306: clear screen failed.\n");
    (void)ssd1306_advance_deinit();

    return 1;
}
res = ssd1306_advance_string(0, 0, "123", 3, 1, SSD1306_FONT_16);
if (res != 0)
{
    ssd1306_interface_debug_print("ssd1306: show string failed.\n");
    (void)ssd1306_advance_deinit();

    return 1;
}

...

res = ssd1306_advance_write_point(38, 38, 1);
if (res != 0)
{
    (void)ssd1306_advance_deinit();

    return 1;
}

...

res = ssd1306_advance_rect(0, 31, 31, 31, 1);
if (res != 0)
{
    (void)ssd1306_advance_deinit();

    return 1;
}

...

res = ssd1306_advance_fade_blinking(SSD1306_FADE_BLINKING_MODE_BLINKING, 0);
if (res != 0)
{
    (void)ssd1306_advance_deinit();

    return 1;
}

...

res = ssd1306_advance_vertical_left_horizontal_scroll(0, 7, 0, SSD1306_SCROLL_FRAME_2);
if (res != 0)
{
    (void)ssd1306_advance_deinit();

    return 1;
}

...

res = ssd1306_advance_picture(0, 0, 0, 0, image);
if (res != 0)
{
    (void)ssd1306_advance_deinit();

    return 1;
}

...

(void)ssd1306_advance_deinit();

return 0;
