Jaques, thanks a lot.

It works for me even without the RESISTOR IN OSC.  Is it really needed?
I've used Arduino Mega 1280.

Hi Guys,

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.

Datasheet:

Thanks in advance (again) :-)

Hi,

I'd like to know what is necessary to make this code works with Holtek HT6P20 or HT6026. Is there any library for this chip available to download?

I'll appreciate any kind of help.
