Hi fK1G6HBzdnOY

I would hear if could get the same information as RaMaBo, while I'm going to rebuilt the touchpad with physical buttoms. 

It would be really helpfull, so i dont have to attempt all combinations myself with a scope. 

Thanks!

Dear Landgrebe,

please find attached a zip file, which should include all you need for converting a BeoSound3 from touch panel to Beo4 control.

Some additional info is inside the source code. If you're interested in how the software works, have a look inside "b&o.cpp".

Btw., Roger245 has made this conversion this year with success. The only problem he had was that he bought a hotel version of Beo4.

Normally these hotel versions are not usable so take care when buying a used Beo 4. For some models of Beo 4, I think older ones, which are containing an EEPROM 24C16, I was able to modify the EEPROM's content to make them work but this will add some more unnecessary work to the project.

Reengineering of the information I've needed to do this project and writing the software for the project took some time. I've used some information from the web (e.g.: MLGW Protocol specification [http://mlgw.bang-olufsen.dk/source/documents/mlgw_2.24b/MlgwProto0240.pdf]), which I've got for free. What I would like to say is:

It's allowed to everybody to use the information I've attached to this post but I would not like that someone will earn money by using this information. It's OK to share or modify all this information. All things and knowledge based on this information must be free of charge.

Yours sincerely

Genius! Thanks for your work and contribution.

Hi fK1G6HBzdnOY

Many thanks, I will use this code with my own personal project, with more simple panels, when i dont use all the funktions. I will use some of your code aswell and modify it to another MCU. 

Again thanks!

Best regards

Landgrebe
