Add to your ESP-IDF project using the component manager:

idf.py add-dependency "whirlingbits/wb-idf-core^1.0.0"

Or add to idf_component.yml :

dependencies:
  whirlingbits/wb-idf-core: "^1.0.0"
#include "wb_idf_i2c.h"

// Initialize I2C bus
i2c_master_bus_handle_t bus_handle;
wb_i2c_master_bus_init(I2C_NUM_0, GPIO_NUM_21, GPIO_NUM_22, 100000, &bus_handle);

// Add device
i2c_master_dev_handle_t dev_handle;
wb_i2c_master_bus_add_device(bus_handle, 0x3C, &dev_handle);

// Write data
uint8_t data[] = {0x00, 0x01, 0x02};
wb_i2c_master_byte_write(dev_handle, 0x00, data, sizeof(data));
