Hi! Is it possible to replace the screen on a Devo 10 to OLED? Would this work? www.ebay.de/itm/281868222515

Sincerely

That display has a SSD1309 which has a very similar command set to the NT7538 on the Devo10. so it might 'just work', but I wouldn't be surprised if changes were needed to the code. The chip is normally hooked up in quadrants and it is possible they aren't the same for this display. Also, there may be some differences in the command list. You could certainly try it, but if you aren't comfortabel with C coding and buidling your own firmware via docker, it is likely to not be successful.

Thanks for replying PhracturedBlue. I'm not very good at software. Hardware and modification is more my area. But do you know any OLED or TFT screen that would work straight off? Otherwise, I get to learn c coding and build the firmware via the docker. Are there any guides on how docker works, and do you know where I can find good study materials for c coding?

What you found is probably as good as you are likely to find. The problem is that you can't know until you try it

Hah, that is cool.
Is it your devo? Do you still have original screen? Could you measure current drain with original screen and with OLED? Just for giggles? :-D

My Devo 10 screen has a column out so this got me looking around. Ordered this one to try. It's close in size to the stock module. The SSD1305 seems very similar to the 1309 so hopefully not much work :)

Anyone know the connector on the far end of the display module wire harness (the part that plugs in under the USB)?

I want to note that the 7e screen is different and there will most likely need to be a code change to support such a screen on the 7e. Basiclaly the lcd driver for the 7e is different than the devo10 even though the driver is the same. This is because the 7e has the quadrants coded differently for some reason. So even if the devo10 can do a direct swap, don't expect the same to be true of the 7e.

Keep us updated! :) I've not decided what screen I'm going to buy yet. :)

I think the connector to mate with the Devo 10 is JST PHR-16. Should have everything in a week.

No joy just plugging it in with no changes. Likely not plug'n'play, or I got some wiring wrong, or the module's bad :) But just got some work so won't have much time to spend on this for a couple weeks.

Stock walkera firmware worked fine with modified I2c OLED screen. Mod screen to serial which was fiddly but go steady easy enough. I used the screen ribbon to make hardware changes to convert I2c>serial.
LCD I used was compatible with NT7 driver. Last line should have been the first line. Screen broke before I found out why. I had used screen with arduino using same initialising code as deviation worked and looked great. There is a pcb layout I'd done on bitbucket.org/SadSack/lcd-multi-spi-flash
All details where to get screen from.

Hi anthony7288

Is this screen easily swappable by a novice or much more is involved like software or more than rudimentary soldering. Thanks

What I mean is, what is involved in replacing this screen, just remove the old one and replace this one with no problem ?
