Servo controlled infrared transmitter
Based on the nice IR decoder/encoder routines (IRMP/IRSND) from Frank Meyer => http://www.mikrocontroller.net/articles/IRMP
 
Application examples:
- Remote control for a camera on a RC-model through normal servo channels.
- Control for a TV at home. Doorbell connected to one input - switches the TV to a surveillance cam.
- Control for a stereo at home. Motion sensor connected to one input - pump up the volume to scare a housebreaker.
 
The idea for this project came up, to control a HD-camcorder on a Mikrokopter with a second radio-transmitter.
Gas-Stick: Zooming Camera
3-way Switch: Stop/Picture/Movie record
Nick-Stick: Cameraholder-Nick
Roll-Stick: Cameraholder-Roll
 
 
Inputs:
2 channels for servo-signals, switches or other TTL signals
1 IR-Receiver to learn new codes (36 - 40 kHz)
 
Output:
Modulated infrared signal at 950 nm
 
Controls:
1 LED to indicate several operating modes
1 button to enter/leave the learning mode and switch between single and multi mode
 
Supply voltage:
5V DC @ 50 mA
(Attention when using RC-Receivers with higher voltage)
 
 
Theory of operation:
 
Each channel is seperated into 5 states, depending on the positive pulse width:
0,00 - 0,74 ms => 0 (switch to GND)
0,75 - 1,24 ms => 1 (stick down)
1,25 - 1,74 ms => 2 (stick middle)
1,75 - 2,24 ms => 3 (stick up)
2,25 - more ms => 4 (switch to VCC or open input)
 
Together with the second input, you get theoretically 25 different combinations, which all can be populated with learned IR-code.
 
When using servo signals only, you have 3 states per channel, so 9 combinations.
When using switch signals only, you have 2 states per channel, so 4 combinations.
When mixing both signals, you have 2 states for the switch and 3 states for the servo, so 6 combinations.
When using only one channel, you get 2 (switch) or 3 (servo) states.
 
After power-up, the device checks the inputs the whole time. When a combination was learned with an IR-Code before, this code is sent out through the IR-Diode. Depending on which mode this combination was learned, it is sent out only once (single-mode), or as long as the combination stays active (multi-mode).
When the device sends out IR-Code, the red LED lights up.
 
 
Theory of learning:
When you press the button on the device, it goes to learning-mode.
In this mode, the LED flashes 1 or 2 times (depending of the actual mode) every half second, indicating that the device is waiting for IR-codes.
When pressing the button again, you can choose between single- or multi-mode.
 
When an IR-code is sent to the device, it looks at which state-combination the inputs are, and saves the IR-code for this combination.
Saving is confirmed with fast flashing of the LED.
You can now learn multiple combinations with different (or same) IR-codes, you can even mix up different IR-protocols and use different modes on different combinations.
When you have learned enough, press the button for 2 seconds, to permanently save the data to the EEPROM. This is confirmed with fast LED-flashing.
The device goes back to normal operation and is ready for orders.

The code was compiled using WinAVR-20081205. Other versions generate much bigger code which don't fit in the ATMega8 anymore. To avoid this, use another WinAVR version or disable some IR-protocols in irmpconfig.h and irsndconfig.h
