You'll need to install a library to make Arduino IDE support the module. This library includes drivers for the transceiver and sample code for you to jumpstart your project.
Software
For ESP32 based systems, we're currently supporting Arduino core. Please make sure you've installed the following:
Arduino IDE.
ESP32 Hardware libraries for the Arduino IDE.
Python for the compilation of Arduino projects.
Drivers for your host device, e.g., USB Virtual Serial Port driver.
Then, copy its contents to your Arduino Libraries folder.
You can find the Arduino Libraries folder inside your Arduino sketch directory. It is generally located inside the My Documents folder.
Samples
The library comes with included samples. There is no need to download additional files for the examples.
Source Code
The hardware, its drivers and the sample code are open source. You can use them under the terms of the MIT license. Please feel free to customize and prototype them for your projects.
Arduino Library
Turta_IRRemote_Module library is responsible for encoding and decoding IR remote signals.
To use the library on Arduino IDE, add the following #include statement to the top of your sketch.
1
#include<Turta_IRRemote_Module.h>
Copied!
Then, create an instance of the Turta_IRRemote_Module class.
1
Turta_IRRemote_Module ir
Copied!
Now you're ready to access the library by calling the ir instance.
Initialization
To initialize the module, call the begin method.
1
begin()
Copied!
This method configures the PWM and INT pins for IR communication.
Basic Members
Set Reception
Configures the driver to listen for incoming IR signals.
Returns true if any message is received and ready to be read.
1
bool isMessageReceived()
Copied!
Parameters
None
Returns
Bool: Message Received State
​
Get Data
Reads NEC protocol IR message from the driver buffer.
1
voidgetData(byte d0, byte d1, byte d2, byte d3)
Copied!
Parameters
Byte: d0 out
Byte: d1 out
Byte: d2 out
Byte: d3 out
Returns
None
Examples
You can open the example from Arduino IDE > File > Examples > Examples from Custom Libraries > Turta IRRemote Module. There are two examples of this sensor.
If you're experiencing difficulties while working with your device, please try the following steps.
Problem: The IR Module does not recognize NEC protocol messages.
Cause: To capture IR messages, the software decoder should be activated.
Solution: Please call setReception(true) method to activate software decoder.
