Hello,
I am preparing very cheap external IR receiver connected via USB or RS232TTL which will alow you to use others remote controls (for example from others set-top-box).
I already prepared prototype hardware connected via USB and using it on H2H set-top-box.
I can use any remote using NEC protocols. Support for remotes using others protocol can be easy added if I have such one.
The core of this hardware extension is ATtiny2313 mikroprocesor. To be able to connect it to STB via USB I used cheap PL2303HX and IR decoder TSOP4838.
Cost of all used hardware component is less than 4$. If your set-top-box have RS232 port or you can open your STB and locate RS232 TTL on the motherboard then then you can connect it directly.
So, PL2303HX will be not needed (made hardware cheaper) and it will not take USB port.
When I have some time I will provide schemes with pictures and instruction how/to. I think that this project can be useful for many users ![:)]()
Many, even good set-top-boxes, have not, so good remotes. This can cause frustration, sometimes.
With this very cheap hardware extension this will be no more problem.
Are you interested with such hardware?
