Universal IR remote IC

ir remote ic

Hi,

could anyone suggest a Universal IR remote IC solution like this:

but cheaper?

It's pretty nice and ~$38, but the minimum order is $500...

What exactly are you interested in doing? It you want to have a fully configurable remote but do not need to actually control it via a serial port, then search for "JP1". These remotes can be custom configured with a small cable attached to a printer port. With free software you can write macros for the remote, reprogram the buttons, add new protocols, etc.

If you are trying to develop a device that can be operated by remote control. Then look at a microcontroller using one specific remote protocol. A very popular one is the Philips RC5 protocol. There is a lot of code available for PIC and AVR micros that will do that protocol.

Finally, did you ask Innotech who their distributors are? Often times the distributors will sell to you without the minimum order quantity.

Sorry for the delay,

I need a working Learning IR module, it will be used in my home control system.
I don't have time to implement one, also there are many protocols, that's why I looked for a ready made solution.
I want to attach it to my RF controlled MCU and control the TV / AirCo etc.
The innotech one looks promising, I'll ask them as you suggested.

I'll checkout JP1.

I wrote them a couple of days ago, but no answer...

I did stumble across the fact that the "ALL in One" remotes used to have the ability to connect to serial ports. Some details can be found at:

The models known to have this feature are:
URC-2005 One For All 5 "Upgradable"
URC-2093 One For All 3 "One Call 3"
URC-2094 One For All 4 "One Call 4"
URC-4000 One For All 6
URC-4005 One For All 6 "Upgradable"
URC-4050 One For All 6 Hi-Fi "Upgradable"
URC-5000 One For All 12
URC-6050 One For All 8 Hi-Fi "Upgradable"
URC-6800 One For All "VCR Pro 8"
URC-6885 One For All "VCR Pro 4"

Sadly, these do not seem to be current model numbers. Perhaps the same feature is still available in current remotes or perhaps it was discontinued.
It would be a very handy feature to have. While I have written IR protocol code before, I cannot see why I should re-invent the wheel. I am perfectly happy writing the timers, state machines, and control functions for my particular needs and then leave the grunt work of actually coding the protocol to a dedicated chip or device.

It is not too difficult to write your own. I have done this successfully on both the 8051 and AVR. Use a TV IR remote receiving device. Gives TTL compatible signal out and handles 40Khz filtering etc. Connect the output to an interrupt pin. Set int that it occurs on both pos edge and neg edge. Then capture the length of each hi an lo pulse into an array. For playback you read the time from array. The first record should be the 'On' . Keep output led on for this time and then off for the time in next record of array. You should modulate the output at 40Khz. This can be done by another timer in the cpu or by external hardware. It helps if data can first be sent to a PC then you can 'clean it up' so that it takes up less storage, but this is optional.
