I2C OLED Display Library

This library provides functions and structures for controlling an I2C OLED display using the ESP-IDF framework. It includes features for drawing pixels, characters, BMP images, and XBM images on the OLED display. The library is designed to work with the ESP32 microcontroller.

Usage

• Initialization
• Drawing Pixels
• Drawing Characters
• Drawing BMP Images
• Drawing XBM Images

Structures

• i2c_oled_t
• bmp_t
• xbm_t

Functions

• i2c_init_master
• i2c_oled_refresh
• i2c_oled_clear
• i2c_oled_init
• i2c_oled_draw_pixel
• gen_bmp
• draw_bmp
• gen_xbm
• draw_xbm
• i2c_oled_draw_char
• i2c_oled_text_newline
• i2c_oled_invert_line
• i2c_oled_reset_cols
• draw_char
• i2c_oled_draw_string

Example usage

#include <stdio.h>
#include <string.h>
#include "I2C_OLED.h"
i2c_oled_t oled =
{
		I2C_NUM_0,
		GPIO_NUM_21,
		GPIO_NUM_22,
		0x3C,
		64,
		128,
		0,
		NULL,
		{-1,-1}
};
void app_main(void)
{
    i2c_init_master(&oled);

    i2c_oled_init(&oled);
    i2c_oled_clear(&oled);
    i2c_oled_draw_string(&oled,"Test",4,1);
    i2c_oled_refresh(&oled);
    while(1)
    {
    printf("Ping !\n");
    vTaskDelay(1000/portTICK_PERIOD_MS);
    }
}
