I'm not sure if I did it all right, but it wasn't really important to me as long as it could send the codes I needed. I only had to modify an include file to make the existing NEC remote routine interpret and send Yamaha codes.
The real workhorse here is this guys IR library:Īrc Language Blog: An Arduino universal remote: record and playback IR signals (they are pulsed via switching transistor) The IR led's seem to draw a lot of current so I put a 1000uf cap on the power rails. never used the crappy remote anyways) and an old IR remote which I broke in half and soldered a header on to. the 3 pin IR receiver from an old Audigy LiveDrive (those 5 1/4 drive bay things with jacks and such. Being lazy/forgetful like that, I ordered an extra boarduino a while ago to solve the problem. Thing is, I have been putting my computer to sleep for a few years now, but I always forget to turn the receiver off. It uses enough current to keep it warm even if sound isn't coming out of it. This is a large external receiver, a Yamaha RXV663. So I have a large 7.1 surround system hooked to my computer for games and watching movies (when the 720p projector is on). * IRremote lib Copyright 2009 Ken Shirriff * electrosthetics IRremotePowerSave: power saving project - microcontroller side The button is just a simple on/off, totally optional. Here is the code for the microcontroller, it simply gets a byte from the serial port and decides what to do based on its value. Optionally, the default sound device is polled via DirectX and any changes detected cause an IR code to be sent to change the input on the amp. Remember to read the readme and put your audio device guid's in the config if you want the audio output polling feature to work.Ī windows power management event triggers a byte to be sent to the microcontroller, which then sends out an IR code. Here is the service, source code and installer included: downloadĮdit: This was updated 1/22/10, fixes: config file was not being read properly, added shortcuts to configuration folder and start/stop commands for service.
