USB Infrared Toy / Re: irtoy recorder perl script
You are correct. Just updated the wiki with instructions how to install needed perl module depending on the platform (ActiveStatePerl, Ubuntu, RedHat, FreeBSD)

USB Infrared Toy / Prescaler setup in sampling mode
Hi,
Reading this wiki page. When setting this value, is it expected IRToy to respond on success/fail as BusPirate?
When sending 0x05 0x0n (n is 0..7) I do not receive response (0 or 1) but when send something with remote, the capture is different, but not as I expected.  See the screen shots. Every capture is with same remote button (Power) code.
I expected that after setting [0x05,0x07] I should capture same data as the default one. When I set [0x05,0x06] I expect to see 2x greater values that i shoud multiply with 21.3333/2=10.6666 to get same value. when set [0x05,0x05] I should receive 4x greater values, and so on... Or I am wrong?

USB Infrared Toy / irtoy recorder perl script
Hi,
Finally I managed to cleanup the code of my Perl script for recording data from IRToy.
Currently it is working with Win32::SerialPort module (windows only AFAIK).
Change COM4 to other COM port if needed;
There is a 'secret' function to dump (to stdout) the received bytes and the calculated time. To enable this function just create an empty file with name 'irtoy.dump' in the folder where the script is running.

USB Infrared Toy / PANASONIC EUR648251 decoder perl script
Hi,
This Perl script decodes commands from PANASONIC EUR648251 remoce. The protocol is similar to NEC but with different timings and 6 data bytes encoded.
According  to this lirc file the decoder is working (pre_data is the same and the codes are correct too). The attached bin file contains 'Power','1','2' and '3' button codes.

Only last 2 bytes are different so maybe the first four are device descriptors and/or addresses?

USB Infrared Toy / Re: ir2PNG Perl script
Hi Ian,
I am glad that the scripts are useful. There are a lot of hard coded fine tuning parameters but they are working fine with the remotes I have. Currently working on another remote, yet it seems to me like a supplemented NEC protocol. It is for this remote. Details will bi posted on separate topic.

USB Infrared Toy / ir2PNG Perl script
Hi,
Because I am not familiar how to create .ols files and my IRToy cant talk to jawi's OLS client(do not know why) I needed a tool to visualize the data received from the IRToy.
So I wrote an script for reading from irtoy  (the code is ugly) that works almost like the IRToyRedWrite util. Then the dumped bin was passed to this script. The script helped me to have visual impression of the data.

The script require GD::Image perl module!

BR,

USB Infrared Toy / NEC IR protocol decoder
Hi,
The attached perl script is my simple try to decode NEC's IR protocol(details from here). As an single parameter pass a bin file generated by IRToyRecPlay utility.

Usage in cmd prompt:
> ir_NEC.pl dumpfile.bin

Here is sample session:

Open Bench Logic Sniffer / Re: Any plans for a buffer wing?
Well this weekend I just soldered male pins on my OLS. The picture of the buffer wing at GF has male pins too. This sound like problem for me...
So is it possible to sell the wing without TH parts soldered(as kit with SMD parts only)?

Bus Pirate Development / Re: new branch in the svn (newterm)
IMHO pin numbers instead of cable colours is better because BP is sold without cables (as in my case) and the cables are additional option. In my area it is difficult to find any flat cable what to say about coloured in the exact order so I am using piece of cable from old floppy drive data cable...

Bus Pirate Support / Re: Microwire EEPROM Help
AFAIK most of the memory chips has inverted logic of CS signal (/CS), so  '[' means 'drive CS pin low (0V) and ']' means drive CS pin high (Vcc). According to the datasheet in your case you have straight CS that's why you must use them swapped.
