Controling AXA remote 2.0 with KAKU remote
Posted: Wed Nov 06, 2013 10:52 pm
Hi all
As you can read here I was planning to make a KAKU RF remote receiver that controls my 2 AXE remote windows.
With the use of this document
http://files.domoticaforum.eu/Axa/AXA%2 ... nov_V2.pdf
that I found via this thread http://www.domoticaforum.eu/viewtopic.p ... 6&start=30
I now have started development.
First picture
It is connected to the PC via an USB serial cable, To a max232 to convert the RS232 to TTL, and then a MCP2021.
This is almost the same as the MCP2003, except it as an voltage regulator of 5.0v internally that I can uses for the Arduino.
But it was a little bit strange, I couldn't get it to work. because I was sending "status:\r\n" at ones. But When I started typing and directly sending every character it started to work when I don't type to fast ( And I am not that fast :-O.
Second version (first picture) I use a Arduino pro mini 3.3 volt and the same MCP2021. and have a transparent serial to software serial communication.
I used the FTDI with the hardware serial, and connect the MCP2021 to port 3 and 4 for the software serial ( bit banging ).
That one worked pretty quick
Now make a the arduino to type the characters and make some recovery mechanism, because a number of times it didn't work that well.
