Graphical IR remote decoder [AVR->PC] – try your remote

Decoder plus testing transmitter.
This device is used to determine the type of the remote controller. If you have a remote and the symbol of it can't be found on **broken link removed** and therefore, it can't be used for new projects, this device will describe the coding of the remote.
It can be used for any remotes – any digital one (but of course it has some restrictions)



The device shows graphically the signal coming from the remote. It's accurate to 1us. The graph can be shown in 2D, 3D or Zoom.



An interesting option of this device is that the data can be saved to files, to be used in other programs.
The program was written in Delphi, and the program to the microcontroller was written in C.
The data from the microcontroller is sent to the PC by RS232. A serial USB/RS232 converter was used, therefore, the data is sent somehow by USB.

1. processor clock – 8MHz
2. RS232 speed - 38'400bps

The PC program and the compiled program to Atmega8 can be downloaded from Link

Atmega8L on self-made test board:



Examples of decoding remotes:






In the main time, a new version was designed.
New features:

1. the graphical image of the infrared frames can be saved to files
2. the frame can be saved as a text file (with various times)
3. frames from text files can be read
4. the frame read only from a file can be emited (it doesn't have to be received from the microcontroller before)

A frame written manually in txt file can be saved too. Therefore, a remote described on Link can be tried, if it would be good for our device.

A practical usage of this device: if you have a Canon, Olympus or Nikon and don't have a pilot to it, just find the standard of the frame, try it by this device and build it on your own.
