I am doing the DIY kit, and I realized that I have no way to get the IR codes onto my L336 remote that I ordered from aliexpress. I cracked it open and lo and behold it’s just a simple I2C flash chip.
I have managed to dump the chip using a raspberry pi and a SOIC-8 test clip.
If someone would be so kind as to dump their flash chip, I would greatly appreciate it. Additionally, it would be a great asset to have as a download for those who are technically inclined to program their own remote.
If anyone is willing and has the equipment (raspberry pi and some way to hook 4 wires to a SOIC-8 chip, solder or clip), I can provide instructions on how to do so.April 17, 2017 at 9:26 PM #12442
Once I got my OSSC running I can help you with that. I got an old raspberry pi model B. Finding proper clips or soldering wires should not be a problem.April 17, 2017 at 11:50 PM #12446
Awesome!!! I’ll post some instructions later tonight.April 20, 2017 at 5:25 AM #12503
OK sorry for the delay in these instructions.
- Remove remote batteries
- Use some kind of spudger or plastic tool to go around the edge and open the remote (all plastic clips, careful not to break them)
- There are 2 chips, locate the flash, it should be a 24C16N (If it’s not a 16 we can probably still dump it just different command)
- Take your pi, turn on the i2c bus in
sudo rasbpi-config, reboot.
- Get the i2c tools:
sudo apt-get install i2c-tools
- Pinout is:
- 4 – GND
- 5 – SDA
- 6 – SCL
- 8 VCC
- Hook up 4 wires to pi with a clip or by solder
- pi pinout: https://pinout.xyz/
- pin 1 is 3.3V, pin 3 is SDA, pin 5 is SCL, pin 6 is GND on pi
sudo i2cdetect -y 0, you should see addresses 50 through 57 light up in the output.
- dump the flash:
for i in 50 51 52 53 54 55 56 57; do sudo ./eeprog /dev/i2c-0 0x$i -r 0:256 -f -o 0x$i-2.bin; done
- zip up all the
0x5*.binfiles, upload em somewhere, and I’ll let you know if it works!

That seems like a round about way to do it? Have you tried just trying to sync your remote to the OSSC?
Just hold down Button 1 (the one closest to the LCD) on your OSSC as you turn on the power, you LCD will then give you instructions on which button to press, I synced my Yamaha receiver remote without any problems.
Also you can try the automated programming for brands etc of the remote, the OSSC uses NEC standard AFAIKApril 21, 2017 at 5:18 AM #12528
Maybe that will work then, I don’t have my OSSC complete yet. I just got the HDMI chip today, just waiting on the cyclone… Then I will be able to mess around with it. It was fun to screw around with the remote while I’m anxiously waiting 🙂April 21, 2017 at 11:03 AM #12532
Ah yeah =D just got mine up and running a few days ago 😛
