I have always wondered about these pads, especially on the old Vizio double sided remotes with the keyboard attached to the bottom, it’s made of two motherboards with two IR lights pointed in different directions. I remember I would spend hours as a kid testing out all kinds of stuff with the remote and they even have weird little games you could play on these early smart TV’s. (BTW I’m talking about the big one with the A B X Y buttons, not the slim newer one and not the one where the keyboard slides down)
A video on the process of decoding would be incredibly interesting! What tools you use, common patterns you know, etc etc. Really enjoying all of your videos, keep it up :)
2F seems to be transmit, 5F might be receive? (Not sure) I noticed additional patterns in each of the messages as well. It seems each message has three messages in it. I've broken them apart before. As you noted, the same byte is sent in position 3 for each of the three parts, which is always followed up be 48. Perhaps the 3rd byte is a sort of message id for the current packet? 2F 8A7D 48 0A08 2F 9A7D 48 0A08 5F FA7D 48 690D1828F8 2F 3FA8 48 0A08 2F 2FA8 48 0A08 5F 4FA8 48 690D1828F8 2F F9AC 48 0A08 2F E9AC 48 0A08 5F 89AC 48 690D1828F8
7:43 1 Million (Translated to BAUD) is Sym/s SYMBOLS PER SECOND Not Samples and 1MHz is Frequency not BAUD, 1MHz doesn't have to mean 1 Million symbol changes per second, you could have 9600 Symbols in that time, it depends on the BAUD RATE in use in the protocol but.. you were looking for BAUD RATE... in SYMBOLS per second Sym/s or Sym/sec or even Bd
Hi. Thank you for the video. I have a question. The blue LED in the logic analyzer is on all the time, and Logic2 shows that the device is starting from a high state. Is it damaged or is it supposed to be like that?
@@mattbrwn thankful for your empathy but iv been in the game for awhile *no skin lost* got a refund, you shouldn't apologize for the mistakes of others ;p
8:35 it's not Binary Protocol. it's likely NEC Protocol Binary isn't a protocol. it's a Numbering system and a Language, it's not a Protocol also you just said it was HEX so....

This explains why I gotta wait between button presses on these "smart" remotes. Channel surfing is dead now.
haha I know right?
@Arpad Toth 🤣
It would be cool to see how you approach CANbus

More likely an end of just comms check
wow you are a gizmo i stg i watched your whole channel today, addicting seeing what you can do 🙈

Yeah

Its normal
How take Logic analizer in rfid ?
Bought one of these off ebay it never arrived:/ first experience of this but could you recommend a reseller
I got mine from amazon:
www.amazon.com/PCBite-SP10-probes-test-wires/dp/B08FGG1QWD
sorry you had a bad experience :(
@@mattbrwn yeah amazon makes you have a business license to sell but i just dont like their business model i have a small wifi router llc on eBay

Also how about the salea same place? Those were supposed to be my Christmas to myself lmao but THM is just a good present
Cool but you should be able to solder to those points with no issues, those pogo pins just cause more problems than there worth...

Ive been wanting the pcbite kit for so long but the kit i want is like 700cad haha
I like the video but I hate that fuckin hat lol. Good video though, liked and commented for your algo
Life is all about pattern matching…
Woo!
Yes my g ......brillant
