Library for Melexis MLX90640 32x24 IR array. It realizes the configuration and reading of MLX90640. Implement reading, configuration, and display examples to facilitate the realization of your ideas.
- Product Repository - Product repository for the RAKWireless RAK12052 32x24 IR module.
- Documentation - Documentation and Quick Start Guide for the RAK12052 32x24 IR module.
In Arduino IDE open Sketch->Include Library->Manage Libraries then search for RAK12052.
In PlatformIO open PlatformIO Home, switch to libraries and search for RAK12052 . Or install the library project dependencies by adding
lib_deps =
RAKWireless/RAKWireless MLX90640 32x24 IR library
into platformio.ini
For manual installation download the archive, unzip it and place the RAK12052-MLX90640 folder into the library directory. In Arduino IDE this is usually /libraries/ In PlatformIO this is usually <user/.platformio/lib>
The library provides RAK_MLX90640 class, which allows communication with MLX90640 via IIC. These examples show how to use RAK12052.
- RAK12052_32x24_IR_Read_MLX90640 Read the temperature array collected by the sensor and output it through the serial port.
- RAK12052_32x24_IR_Display_MLX90640 Serial output temperature array data and display the binarized graphics through RAK1921.
**bool begin( TwoWire *wire , uint8_t i2c_addr) **
Initalizes the MLX90640 sensor.
| Direction | Name | Function |
|---|---|---|
| in | wire | IIC interface used. |
| in | i2c_addr | Device address should be 0x33. |
| return | If the device init successful return true else return false. |
mlx90640_mode_t getMode(void)
Get the frame-read mode.
| Direction | Name | Function |
|---|---|---|
| return | Chess or interleaved mode. |
**void setMode(mlx90640_mode_t mode) **
Set the frame-read mode.
| Direction | Name | Function |
|---|---|---|
| in | mode | Chess or interleaved mode. |
| return | none |
mlx90640_resolution_t getResolution(void)
Get resolution for temperature precision.
| Direction | Name | Function |
|---|---|---|
| return | The desired resolution (bits). |
void setResolution(mlx90640_resolution_t res)
Set resolution for temperature precision.
| Direction | Name | Function |
|---|---|---|
| in | res | The desired resolution (bits). |
| return | none |
mlx90640_refreshrate_t getRefreshRate(void)
Get max refresh rate.
| Direction | Name | Function |
|---|---|---|
| return | How many pages per second to read (2 pages per frame). |
void setRefreshRate(mlx90640_refreshrate_t res)
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!
| Direction | Name | Function |
|---|---|---|
| in | res | How many pages per second to read (2 pages per frame). |
| return | none |
**int getFrame(float *framebuf); **
Read 2 pages, calculate temperatures and place into framebuf.
| Direction | Name | Function |
|---|---|---|
| in | framebuf | 24*32 floating point memory buffer. |
| return | 0 on success. |
