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.
