I have a 50W LED driver with a IR remote control that i want to controll with a microcontroller.LED driver I hooked it up to my oscilloscope to try to decipher the data sent between the IR reciever and the remote, but couldn't recognize the protocol used, and the PicoScope software couldn't figure it out either. Any idea what it is? The short 0 pulses are approx. 0.52ms long

Here is a picture of the reciever: enter image description here

  • \$\begingroup\$ the model is unfortunately "generic Ebay", all info about the driver i have is shown in the first image \$\endgroup\$ – Pownyan May 19 '17 at 18:43
  • \$\begingroup\$ RC5 maybe en.wikipedia.org/wiki/RC-5 \$\endgroup\$ – Trevor_G May 19 '17 at 18:48
  • \$\begingroup\$ That wouldn't explain the long MAB in the beginning of the data \$\endgroup\$ – Pownyan May 19 '17 at 18:50

    \$\begingroup\$ www.sbprojects.com/knowledge/ir/ there is a pull down on the top right of the page you can walk through the different protocols, look for the ones that have a sync pattern that starts like taht (some dont have a sync pattern easy to rule out) \$\endgroup\$ – old_timer May 19 '17 at 19:22

There are no lots of protocols used for IR remote controller. Probably RC 5 or NEC.

If you take apart the remote, you could probably find a chip with markings on it - then you know.

  • \$\begingroup\$ the pcb on the remote has a big blob of black resin covering the IC, so no luck there \$\endgroup\$ – Pownyan May 19 '17 at 19:03

    \$\begingroup\$ @Pownyan Hook the IR receiver (if you have some) on arduino and try some NEC libraries to decode. \$\endgroup\$ – Marko Buršič May 19 '17 at 19:07

The "W28" IR remote control for generic Chinese LED lamps uses NEC protocol.

A detailed analysis with Arduino code can be found here.
