FYI: IR sample shows ways of using the RAW IR capabilities of the PSP hardware.
Can be used to control many "Consumer IR" devices that use regular IR remote controls
[not limited to "SIRCS"; nothing to do with IRDA]

This is not meant as a "universal remote". The technology provided here can be used to write/port other IR programs.

The 3 examples I picked are: RoboSapien Robot, ICybie Robot and the RC6 remote control commonly used for Windows Media Center.
The way IR signals are encoded are not standardized. Typically each device manufacturer makes up their own encoding scheme.

See "FANCY" source code version if you want to change the features of the full version of the app. For incorporating into your own program see the "SIMPLE" source code version (minimal UI).

wow.

Amazing job.

Very low level tricks here !

Hope someone will take time to make a fancy gui and add reading (universal remote) capabilities.

Do you think reading is possible ?

I can't wait for your wifi sample .03 with sceUtilityNetconf in it and real handler for connection (dhcp ?).
I took time to disasm wipeout but get bored...

Thanks for all your work for the PSP community psppet.

Very impressive! Thanks for sharing the code ...

RC6 is also used in Philips TV remotes... (reminiscence of old electronic-related readings)

EDIT: Maybe was used.. not working on my 1yo Philips TV

Don't know. IRDA reading technology can be sometimes tricked to read "Consumer IR" signals - but that is rare depending on the hardware (and whether hardware pre-filters the IR input). Transmitting IR is usually more general.
FWIW: I use a CLIE for recording/analysing IR signals.

If someone were to make a CCF reader and interpreter (ie. an emulator for a Pronto remote), that would cover many of the needs for a "Universal remote" without hardware recording. If someone want to give that a shot, that would be cool.

NOTE: similar to the "Perfect Remote" on certain CLIE models. It handles many CCF files with the weakness of not being able to record non-standard ones.

The "RC6" protocol describes the top level encoding.
It can be used in several ways. I am using the "mode 6A" as described here: http://www.xs4all.nl/~sbp/knowledge/ir/rc6.htm
Inside that format are Media Center specific remote control codes.
A Philips TV will probably use "mode 0" and Philips specific control codes.

That's why it is impossible to write a truely "universal" remote control. The challenge is to find all the different encodings and include them all, for every IR remote controlled device on the planet...
Most open source implementations fall short. Commercial products typically have their own database of remote code.

A Pronto hex code reader would be perfect.

There are codes (discreets too!) for most brands on remotecentral:

I was attempting to use some of these utilitys to convert the pronto codes to an RC6A bitstream, but have not had much luck. There is a ton of information about the pronto format and conversions on this site (all the way at the bottom) http://home.tiscali.nl/m.majoor/projects__remote_control.htm

Nice idea! PspPet

but it seems not work to me

i use this Media Center Remote (OEM by Philps)
it's usual ,isn't it? Some microsoft's document says it use RC6(not very sure.)


the led on my Remote's IR receiver will flash when i press some key on my PSP, but not work

is there anything i miss to get it work?

my psp is ver 1.50, test on Windows XP Media Center edition 2005

> ...but it seems not work to me
Try turning off the "debounce" feature of Media Center.
As described here: http://blogs.msdn.com/mswanson/archive/2004/12/01/272766.aspx
[change registry setting, reboot]
This is a common problem for "universal remotes" (the PSP version tries to emulate the real remote, but obviously isn't working well enough)

I've been doing some more research on the Pronto Code format, and trying to find ways to convert pronto codes to bitstream format that the PSP can understand. Then by using PSPPet's IR_SIGNAL_ON() and IR_SIGNAL_OFF() generate the correct pulses to control some of the IR gear.

I don't know too much about C, but I know enough about Pronto codes to be dangerous, so I'm posting what I do know so maybe someone else with the C coding skills can use it to make PSP compatible pronto codes a reality...
