Sorry I wasted somespace there Learning this BBS format This thread was started do I can post information on other iR protocols other than thoose in the iR for the boe-bot book. I am currently working on a iR remote for my rokect launcher using a bs2p (on a BoE), PSC, and the s3 tilt/pan kit from crustcrawler, & a memsic acceleromiter (prob spelled that wrong) many people have been very helpfull with my project thus far and I will credit them as I post... Stay tuned more details tomorrow... now I CODE!
I had a hoorid time understanding the data from the JVC RM-RK50
Remote that goes to my mp3 car stereo, after calling parallax and changing the
pulse in statements to diplay the time in .8uS unit vs. the bs2's 2uS units, I still
had no luck my data still meant nothing however, is was consistantly junk so
either the timing was off or something overlooked. A eMail to andy lindsay was in order...
the protocol....
" Here is a link to a web page that has the JVC protocol.
You may also be able to glean keywords from this site to search other
sites on Google that will help you get it sorted out.
Thanks and acknowlagments to San Bergmans, Sid Weaver, and Andy Lindsay
This site was a great resource (p.s. JVC's tech support even for their service tech's is a nightmare)
Turns out they use Pulse Distance Modulation, sounds like another word for PWM but it's not.....
The pulses are allways 526uS (this explains my screwy data!) the way data is transmitted is
by the distance from the start of one pulse to the start of the next. I just used my school's FLUKE(R) 123 SCOPEMETER
to examine the pulse train and indeed all the pulses are the same and looked just as they do on the
KB mentioned above. It turns out my O-Scope was not accurate enough to display them well enough
to decode, the FLUKE worked great and becasue the PNA4601M iR Reciever from parallax displays
negitive pulses and the KB documents show positive, I inverted the display ( if any one cares this scope
is bangin! it'll invert the pulse train calculate pulse times without you having to count grids! be-e-utifull!!)
now I have the codes in case any one wants them:
JVC RM-RK50 Remote Codes
(address)/(Command)
00001110 1000 1110 power
00001110 0100 1110 sound
00001110 1101 0110 up
00001110 0101 0110 down
00001110 0011 0110 reverse
00001110 1011 0110 forward
00001110 1110 1110 source
00001110 0101 1110 vol -
00001110 1101 1110 vol +
I seperated the command part to make it easy to read, also note the LSB is first and MSB last
more later... -=NoOdLeS=-
