Unable to transact using I2C with MPU6050

Hi All,

I am trying to read the value of the WHOAMI register of MPU 6050 using I2C interface. I was unable to find a function directly for register R/W. so, using the adapter, i have used this code.

eeprom_data_reader(EEPROM_24FC256, 0x75, page_buff);

Page_buff is empty and will receive the values after reading.

tatic uint16_t eeprom_data_reader(i2c_device dev, uint8_t pageAddr, uint8_t *buff)
{
uint8_t e_addr_buff[1];

/* Fill in the address bytes */
e_addr_buff[0] = pageAddr;
//e_addr_buff[1] = 0;
//e_addr_buff[1] = pageAddr >> 8;

/* Open the device */
ad_i2c_handle_t dev_hdr = ad_i2c_open((ad_i2c_controller_conf_t *)dev);

I2C_error_code = ad_i2c_write_read(dev_hdr, (const uint8_t *)e_addr_buff,
sizeof(e_addr_buff), buff, EEPROM_24LC256_PAGE_SIZE,
HW_I2C_F_ADD_STOP);

if (I2C_error_code == 0) {
/*
* When maximum data size has been reached, roll over to the starting
* address.
*/
printf("read successful\n");
// pageAddr = (pageAddr + EEPROM_24LC256_PAGE_SIZE) % EEPROM_TEST_DATA_SIZE;
} else {
printf("\n\rUnsuccessful I2C read operation with error code: %d\n\r",
I2C_error_code);
}

/* Close the device */
ad_i2c_close(dev_hdr, false);

/* Return the next EEPROM page */
return pageAddr;
}

I am not able to read the correct values from the sensor but it is consistently giving the value 0x72. If I disconnect the sensor, then the program is able to detect that.

I suspect the way the address is sent to the I2C bus. Am I missing out on something?

Thanks,

Sandeep.
