Convoy S11 XHP50.2 driver - reflashing

oweban · 2019-04-25T11:17:59.000Z

I’m starting to think about the possibilities of re-flashing the driver in the S11 (FX-50), as the current mode-spacing isn’t to my liking, and I’ll be getting a reverse clicky switch for it as soon as Fasttech ship it. With that in mind, I’m wondering if this driver is able to be flashed, and if so, what with.

I think the main chip it has is a 12F683, and I’ve taken an image of it:

There’s other things on there too, and I took a photo of another one that was on there:

Any help would be great. Thanks!

I’ve run into the same issue with KD’s FX-35 driver. Like yours, mine also has the same MCU.
I’m under impression that yes, you can reprogram it, however i wasn’t able anything worthwhile to use as sample code. I’m a high level software developer. Being so close to the metal is totally new to me.

If its not locked you can . If locked, get a new one.

Yeah, re-soldering isn’t much of an issue. Its the firmware side that is tricky.

I put Andúril 2.0 on a Convoy M3 Flashlight Modding and DIY Parts

Hey guys, I just finished putting Andúril 2.0 on a Convoy M3 and wanted to share the process with you (even if not greatly detailed, if you have any questions feel free to ask). But first, here's a video: [ToyKeeper’s Andúril 2.0 on Convoy M3] Andúril really lifts this ~$30 light to a whole new level! The boost driver in it looks like this: [image] [image] I did some reverse engineering on the driver and all I had at hand was an ATtiny85, so I went with that. Wi…
