Remote Control

I eventually gave up on the idea of trying to prod the serial port on my Astro STB and bought a cheap IR transceiver from some guy in Hong Kong via ebay. My first attempts at learning the remote codes were frustrating - irrecord complained about something being wrong after incorrectly guessing the settings, and when I finally got some codes learned, I found that a lot of the buttons had the same code, so 2, 6 and 8 were all being detected as KEY_2. Eventually I started trying to manually configure the basic settings based on some of the standard protocols, and eventually hit on RCMM-32, which learned all the codes and can reliably detect them when I press the buttons on the remote.

So now the codes are learned, along with the codes for the extra buttons for controlling a Panasonic DVD player on the bottom of my TV remote, which have now found a use giving basic control of Freevo in case the wireless keyboard, bluetooth equipped mobile phone or one of many wifi equipped gadgets is not close at hand.

Next step is to go the other way and send the codes out to the STB. The transceiver doesn't seem to be sending anything out at all. I still haven't narrowed down the problem, it may be a faulty IR LED, or an incompatibility between the transceiver (MCEUSB gen 1) and the software driving it (LIRC 0.86). Now that I have the remote codes, it might also be a good time to go back to trying the serial link, but that'll have to wait for another night. For now, I'll just post up the Astro remote codes, in case anyone else is struggling to get them working with LIRC.

I haven't found any way for the dsr4201 to control or be controlled by anything.
