Detailed Description

Class that stores state and functions for interacting with the MLX90640 sensor.

Member Function Documentation

begin()

boolean Adafruit_MLX90640::begin	(	uint8_t	i2c_addr = MLX90640_I2CADDR_DEFAULT,
		TwoWire *	wire = &Wire
	)

Sets up the hardware and initializes I2C.

Parameters

i2c_addr	The I2C address to be used.
wire	The Wire object to be used for I2C connections.

Returns

True if initialization was successful, otherwise false.

getMode()

mlx90640_mode_t Adafruit_MLX90640::getMode

(

void

)

Get the frame-read mode.

Returns

Chess or interleaved mode

setMode()

void Adafruit_MLX90640::setMode

(

mlx90640_mode_t

mode

)

Set the frame-read mode.

Parameters

mode	Chess or interleaved mode

getResolution()

mlx90640_resolution_t Adafruit_MLX90640::getResolution

(

void

)

Get resolution for temperature precision.

Returns

The desired resolution (bits)

setResolution()

void Adafruit_MLX90640::setResolution

(

mlx90640_resolution_t

res

)

Set resolution for temperature precision.

Parameters

res	The desired resolution (bits)

getRefreshRate()

mlx90640_refreshrate_t Adafruit_MLX90640::getRefreshRate

(

void

)

Get max refresh rate.

Returns

How many pages per second to read (2 pages per frame)

setRefreshRate()

void Adafruit_MLX90640::setRefreshRate

(

mlx90640_refreshrate_t

rate

)

Set max refresh rate - too fast and we can't read the the pages in time, start low and then increment while speeding up I2C!

Parameters

rate	How many pages per second to read (2 pages per frame)

getFrame()

int Adafruit_MLX90640::getFrame

(

float *

framebuf

)

Read 2 pages, calculate temperatures and place into framebuf.

Parameters

framebuf

24*32 floating point memory buffer

Returns

0 on success

getTa()

float Adafruit_MLX90640::getTa

(

bool

newFrame = true

)

Return ambient temperature of the TO39 package.

Parameters

newFrame

If true, will also capture a new data frame. If false, return the value from the last data frame read.

Returns

Ambient temperature as a float in degrees Celsius.
