Thank you for the prompt response.
In fact I'd like decode the HT6P20 (learning code), but I know this chip is not so easy to unveil. As I'm still learning, I don't have advanced knowledge to create this decode.
The idea is to press learning button on Arduino that can store the code sent by the chip (HT6P20) . After that, this remote control registered on Arduino is able to execute some actions.
I have this decode in ASM (http://www.asm51.eng.br/phpbb/viewtopic.php?p=51732&sid=8f5a880ce863a5d44303240c8b408f7a
), but I can not translate to Arduino.
Thanks in advance (again) :-)
