Hi Jens
Thanks for the help.
I use remote control that work with RC5 protocol.
The IR chip works on 38KHz.
I run a simulation and I got that the reg_full is going high '1' and the state machine is getting to finish state, but the interrupt is NOT going down to '0'
I am changing the code to fix it.

I found the bug : they forgot to reset the reg_full on reset. (reg_full <= '0';)
Now it's work fine.
Thanks
