## LibDriver MLX90614
[](/misra/README.md) [](https://www.libdriver.com/docs/mlx90614/index.html) [](/LICENSE)
The MLX90614 is an Infra Red thermometer for noncontact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASSP are integrated in the same TO-39 can.Thanks to its low noise amplifier, 17-bit ADC and powerful DSP unit, a high accuracy and resolution of the thermometer is achieved.The thermometer comes factory calibrated with a digital PWM and SMBus (System Management Bus) output.As a standard, the 10-bit PWM is configured to continuously transmit the measured temperature in range of -20…120˚C, with an output resolution of 0.14˚C.The factory default POR setting is SMBus.
LibDriver MLX90614 is the full function driver of MLX90614 launched by LibDriver. It provides temperature reading, id reading and other functions. LibDriver is MISRA compliant.

### Instruction
/src includes LibDriver MLX90614 source files.
/interface includes LibDriver MLX90614 IIC platform independent template.
/test includes LibDriver MLX90614 driver test code and this code can test the chip necessary function simply.
/example includes LibDriver MLX90614 sample code.
/doc includes LibDriver MLX90614 offline document.
/datasheet includes MLX90614 datasheet.
/project includes the common Linux and MCU development board sample code. All projects use the shell script to debug the driver and the detail instruction can be found in each project's README.md.
/misra includes the LibDriver MISRA code scanning results.
### Install
Reference /interface IIC platform independent template and finish your platform IIC 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
```C
#include "driver_mlx90614_basic.h"
uint8_t res;
uint32_t i;
float ambient;
float object;
/* init */
res = mlx90614_basic_init();
if (res != 0)
{
return 1;
}
...
for (i = 0; i < 3; i++)
{
res = mlx90614_basic_read((float *)&ambient, (float *)&object);
if (res != 0)
{
(void)mlx90614_basic_deinit();
return 1;
}
/* print the data */
mlx90614_interface_debug_print("mlx90614: %d/%d.\n", i + 1, 3);
mlx90614_interface_debug_print("mlx90614: ambient is %0.2fC object is %0.2fC.\n", ambient, object);
/* delay 1000 ms */
mlx90614_interface_delay_ms(1000);
...
}
...
(void)mlx90614_basic_deinit();
return 0;
```
#### example advance
```C
#include "driver_mlx90614_advance.h"
uint8_t res;
uint32_t i;
float ambient;
float object;
/* init */
res = mlx90614_advance_init();
if (res != 0)
{
return 1;
}
/* exit sleep */
res = mlx90614_advance_exit_sleep();
if (res != 0)
{
(void)mlx90614_advance_deinit();
return 1;
}
...
/* delay 2000 ms */
mlx90614_interface_delay_ms(2000);
/* read id */
res = mlx90614_advance_get_id((uint16_t *)id);
if (res != 0)
{
(void)mlx90614_advance_deinit();
return 1;
}
mlx90614_interface_debug_print("mlx90614: get id is 0x%02X 0x%02X 0x%02X 0x%02X.\n", id[0], id[1], id[2], id[3]);
...
for (i = 0; i < 3; i++)
{
res = mlx90614_advance_read((float *)&ambient, (float *)&object);
if (res != 0)
{
(void)mlx90614_advance_deinit();
return 1;
}
/* print the data */
mlx90614_interface_debug_print("mlx90614: %d/%d.\n", i + 1, 3);
mlx90614_interface_debug_print("mlx90614: ambient is %0.2fC object is %0.2fC.\n", ambient, object);
/* delay 1000 ms */
mlx90614_interface_delay_ms(1000);
...
}
/* enter sleep */
res = mlx90614_advance_enter_sleep();
if (res != 0)
{
(void)mlx90614_advance_deinit();
return 1;
}
...
(void)mlx90614_advance_deinit();
return 0;
