PostPosted: Wed Jan 04, 2017 3:10 am    Post subject: What is protocol for TCL TV L32E5390E Reply with quote

Hi,

My TV is a TCL model L32E5390E.
I have used an Arduino with the sample program for the IR library to decode and record the remote's commands.

The program says the protocol is NEC, but the codes appear random. I suspect NEC is derived from the similar header and bit-length.

The codes follow. Is there a hidden pattern or some other protocol present?

Thanks
Jim

I have no idea what your codes are, but our other TCL upgrades are RCA-38, device 15 and the following OBCs:

Since there is nothing constant in your data (normally at least a device and subdevices are constant), it is almost surely "noise".

irdb.globalcache.com has two command sets (three really, but the first two appears (esentially) identical, and coincide with mdavej's list. The second one goes (using IrScrutinizer):

I attached a Logic and found the following:

Header mark 4000
Header space 4000
Bit mark 550
One space 1900
Zero space 950

24 Bit code
The last 3 nybbles are the inverse of the first 3.

The template code worked.

...

This is all compatible with RCA-38 (allowing for some measurement errors); the first "F" in your data indicates D=15 (in our terminology). So mdavej seems to have been right.


IrScrutinizer can generate Arduino code for such signals automatically. See this file, generated from ControTower set #1895. Is this what you are looking for?
