@TOYMAKER thats kinda hard only the IR needs to receive IR TRANSMISSIONS at different frequency for each type of remote devices
LIKE TV is set at mostly 40 khz so you need a IR transmitting diode set at 40 khz,then if using wowwee robots its set at 39.2 khz and a 40 khz diode will not send,then some use 455 khz can't use a 40 khz diode for that even if you have a carrier frequency.
One i made FOR $5 only set for wowwee at 39.2 khz ,but working on a design now that works that will cover all frequency.
One i made connects to any digital port on EZB
i have about 50 or more remotes,25 or more for robots and rest for tv,x10 and more for testing ,but only for my robots.
If you have a good scope and signal generator and different remotes can do the same test i did,
IR codes is not too easy .mostly need a learning remote on the usb-uirt its built in and $39.95
I think X10 is 40khz ,like TV and stereo's or are you using RF control ,if using IR most likely you are anyone using X10 system does need a IR to RF converter,i really love my X10 it covers very outlet and more.
IF you don't understand some stuff i said ask away
EDIT : I did read you have a DSO scope thats good one to have,like my 16 channel DSO i have too
HOPE soon to test and compare you design with mine.
@toymaker I see you said your design works for TV and X10 only need 40 khz transmitting diode and a receiver.
can it control other robots and can another IR sending module like mine work on your design.
I guess the main question is your board universal and software can input your own codes,would be a good idea for IR transmitters that use a different diode and carrier frequency,i found a company that sells 8 pin carrier clock 3 different ones to cover about 6 different IR frequency's total.
I did not say 40Khz, I said the RF (radio frequency not IR) frequency is 433Mhz (megahertz not kilohertz) which is the Pan European license exempt RF frequency for RF controllers and RF car keyfobs etc, I think in the States the license exempt RF frequency is 315Mhz. I think you are getting this mixed up with the IR modulation (carrier) frequency which is usually around 38Khz (like the most commonly used NEC protocol).
Our IR emulator PIC will learn any IR controller command so it could control other robots, I use it to control TV, radio, iPod etc.
The industry standard X10 does not work by IR or RF it works by injecting control codes directly into the actual power wiring. The digital data is encoded onto a 120 kHz carrier which is transmitted as bursts during the zero crossings of the 50 or 60Hz AC (alternating current) waveform one bit is transmitted at each zero crossing.
Yes on x10 i know it uses line carrier by injecting a signal across AC i have the box,using digital data on a 120 khz line
For the receivers that make a rf transmitter ,but also use IR to RF converter they make
SO i guess you design has RF and IR ,Why not use use IR for both ?
Have you tried to control wowwee robots with your design,lot of remotes for robot use both RF and IR
WILL find data on carrier frequency on different IR transmitters,some set at 40 khz some at 38khz mostly tv remotes except for RTI that uses 40 khz and on the wowweee it uses 39.2 khz and then 455 khz
Lot of guys on another forum ask the same question will 38kz or 40 khz remote work on wowwee robot ,answer is always no
I think i know why because wowwee uses 38khz for IR DETECTION,since i repair wowwee robots a lot
THEY use 2 different types of diodes if you open one up and have to replace with exact one.
SECOND since a lot of robots use IR DETECTORS like the sharp GP2D12 does your IR design interfere with it ?
I have 4 HERO robots and it uses RF and one remote wont work on another one unless the crystal is changed,so
my question is will it work on it
Also on the usb-uirt it uses 2 types of IR transmitting diodes at different frequency,can find the link i have about that info also and will post it for you.
Also remotecentral.com has a lot of IR codes for tv's and more in their database
TOYMAKER i found the link about USB-UIRT and how it works ,look at photo is shows 2 IR emitters for different frequency ranges.
NOW on detecting IR it uses a wideband 36-40khz and other one can be added for 56khz
Our system does not need all the codes from remotecentral etc or any database, it learns the control packet bit by bit and then records a copy of each command. when replayed later it sends the identical bit pattern out. This is why our system works for all protocols of IR codes be it RC5 or the wowwee codes.
To summerise we do not decode the IR remote codes, we just copy their bit pattern in real time, and then transmit the copy out when required. The only downside of our system is that you have to teach the codes (once) to the system.
You asked why we use RF in the X10 system, this is because the receiver unit that we wirelessly transmit to from the robot is RF and not IR here is the unit

@toymaker here is a good site for IR codes for woweee robots and about the carrier frequency
wowwee IR codes
Also on the usb-uirt it uses 2 types of IR transmitting diodes at different frequency,can find the link i have about that info also and will post it for you.

usb-uirt remote info
One last question what type of IR codes do you use ,RAW OR COMPRESSED UIRT or PRONTO RAW ?

www.uk-automation.co.uk/products/Marmitek-X10-Transceiver-Module--All-House-Version-TM13U.html
The robot just sends the same codes out that the X10 handheld RF (transmitter) controller would send
Wow I missed another good thread! I need to visit more.
