Matthias, Thanks for the pictures. OK so of the two other interesting chips on the S470: U4 is an I2C connected EEPROM - we don't care about that for IR. U10 appears to perhaps be a Silicon Labs C8051F300 microcontroller or similar: http://www.silabs.com/products/mcu/smallmcu/Pages/C8051F30x.aspx Since the 'F300 has an A/D convertor and has an SMBus interface (compatable with the I2C bus), I suspect this chip could be the IR controller on the TeVii S470. Could you as root: # modprobe cx23885 # modprobe i2c-dev # i2c-detect -l (to list all the i2c buses, including cx23885 mastered i2c buses) # i2c-detect -y N (to show the addresses in use on bus # N: only query the cx23885 buses) i2c-detect was in the lm-sensors package last I checked. (Jean can correct me if I'm wrong.) With that information, I should be able to figure out what I2C address that microcontroller is listening to. Then we can work out how to read and decode it's data and add it to ir-kbd-i2c at least. Depending on how your kernel and LIRC versions LIRC might still work with I2C IR chips too. All presupposing of course that that 'F300 chip is for IR...
