A project to enable infrared code playback using any single digital pin on the Arduino101 development board and a lirc-like input format.
- Arduino101/Genuino101
- Infrared LED 950nm
- Resistor
- Power source (USB will work)
Connect a circuit which looks like this:
Digital Ground
pin 13
+-----+ +------------+ +--------------+ |
| | | | | | | |
| +-----+ + IR LED - +-----+ 73 Ohm Res +----+--+-|
| | | | | | | |
+-----+ +------------+ +--------------+ |
Download the ZIP and install using the Arduino IDE. Alternative installation instructions may be found here.
Pick a digital pin, get an IR LED, and get some .cf files.
You can get your .cf files from the lirc remote database or use lirc to generate your own.
Specify raw codes in an array of constant unsigned shorts and pass them
into the sendRawCode function.
Raw codes must be provided in the form of an array in the format used by lirc under "begin raw_codes".
#define _countof(_Array) (sizeof(_Array) / sizeof(_Array[0]))
int GPIO_PIN = 13; // The pin your IRLED is using.

passing in your structure to the sendRemoteCode function.

sendRemoteCode(&fedders_aircon, ON_OFF, GPIO_PIN);- Currently a 38KHz signal is the only supported output frequency.
- Only a subset of options in the "Remote" are suppoted.
- Interrupts are not masked during the IR code playback operation, which means this library may not be very reliable if interrupts are being used heavily on the system.
