READ DATA FROM MPU6050
This example is run to read MPU6050 data via I2C bus.
u8 IIC_Write_1Byte(u8 SlaveAddress,u8 REG_Address,u8 REG_data)
{
ret_code_t err_code = user_i2c_write(SlaveAddress, REG_Address,
&REG_data, 1);
return err_code;
}
u8 IIC_Read_1Byte(u8 SlaveAddress,u8 REG_Address,u8 *REG_data)
{
ret_code_t err_code = user_i2c_read(SlaveAddress, REG_Address,
REG_data, 1);
return err_code;
}
u8 IIC_Write_nByte(u8 SlaveAddress, u8 REG_Address, u8 len, u8
*buf)
{
ret_code_t err_code = user_i2c_write(SlaveAddress, REG_Address,
buf, len);
return err_code;
}
u8 IIC_Read_nByte(u8 SlaveAddress, u8 REG_Address, u8 len, u8 *buf)
{
ret_code_t err_code = user_i2c_read(SlaveAddress, REG_Address,
buf, len);
return err_code;
}
The basic functions are user_i2c_read() and user_i2c_write().
