hello everyone, I am trying to decode RCMM(philips protocol) using VISHAY TSOP31536 IR Receiver with STM32F207 microcontroller kit. There is sufficient data for RC5 protocol but not even a single site is explaining about RCMM. Even the details of RCMM specified(frame/message details) in documents is quite different from what I extracted from the CRO in lab (e.g. each pulse is coming out as 32 bits of data). Please let me know from where can I find reliable RCMM documentation or any useful help?
I am ready to sign NDA (or any such document) to get useful information about RCMM protocol and its decoding. Waiting for your +v responce..

Have a look at a document in the Classic Pronto Files section authored by Eigeny Eulanov or Eugene Eulanov. It concerns the firmware of the legacy Pronto and how it generates IR.

I don't know of any source of official documentation.  However, the link you provided does describe accurately the 12 and 24 bit versions of RC-MM.  These days, we see the 32 bit version.  Sometimes the 32 bit version is referred to as Nokia32.  

The IRP  notation for Nokia32:
{36k,msb}<164,-276|164,-445|164,-614|164,-783>(412,-276,D:8,S:8,T:1,X:7,F:8,164,^100m)+ 

The exact timing shown in the IRP  as experimentally determined.  Probably the timing shown in your link is more correct.
My notes say: The Nokia32 protocol is one variation of the RCMM 1.5 protocol developed by Philips. RCMM refers to X as "System" and to D:2,S:4:4 as "Customer", but I don't remember where I saw this info.

You might want to ping John Fine in the JP1 forum on Yahoo or send him an RC mail message as I believe his profile is still active.

@Lyndel McGee.. Thnx for your concern. I checked JP1 forum for 'John Fine' but NO such username for the same exists(may be due to wrong spelling), could you please correct the spelling. Or provide me the email-id/other contact info of 'John Fine'.. thnx once again

@Lyndel McGee,, I got the actual name. The correct user name is "johnsfine", he is an IR expert. thank you, lets hope a +v responce

Here is a link to John's profile at JP1:

John Fine is is real name, I do believe. And yes, he is an IR expert. Sorry for any confusion.

Thanx Rob for providing the john's profile but now he is not an active member.

Send him an RCMail from here. His profile is johnsfine.
