So I spent the next hour or so digging into various functions in the DLL and notating which headers are what and ended up with some nicely commented frames in wireshark. Next step is to try and emulate some of these via python in Linux...

After some digging in ghidra I narrowed down a couple of consistent functions such as the fun_CRCMessage? that appears to validate/format the message that gets sent to the device. When I saw the CONCAT14(byBrightness,0x312) I got the idea that this might be visible in the pcap and wow! There it is!

Starting with ILSpy I can look at the external references to the DisplayPadSDK.dll and see how they're being called and what parameters are being passed. This is useful to me because it tells me how the DLL is being used and what kind of data the .dll is working with.

Okay, here's the scoop on the URB frames... Captured a bunch of stuff with wireshark, in this instance the software is sending commands for a 'device reset'. Thankfully some components of the app are written in .NET so I can run em through ILSpy, this gives me a great starting point in ghidra-

I noticed there wasn't a reverse engineering feed so I took it upon myself to make one. Feel free to check it out or drop any suggestions! bsky.app/profile/shad...

Reverse Engineering

Okay, back to studying URB frames... It looks like the device goes into a uboot/debug mode but I'm unable to get my system to talk to it, unsure why. But I also noticed there are some yummy uart test points on the board.

You know, I poked at this thing for a decent amount of time, capturing URB messages, analyzing the windows binaries etc... I open it up and what do I see?? (Tiny internal button) Holding this button while plugging in the device gives me a USB debugger, now to figure out if I can talk to it...

Got a new piece of hardware, a streamdeck like apparatus from mountain gg. The hardware is simple and functional and their software is surprisingly customizable! The bad part is no Linux support 😭 Gonna take a shot at reversing the windows driver and writing some complementary python...

As someone who's bipolar and on lithium, I find it so poetic that lithium was essentially the third atom to form shortly after the big bang, the most manic episode on record.

Accurate

My ideal computing world is one where everyone has a system that can virtualize and run containers of any operating system on the fly. No more single boot OS or vendor lock-in. Just software and hardware. It'd be something akin to proxmox for the average user.

Are we calling raspberry pi addons that stack from the bottom 'shoes' or are they still 'hats'?

Please help. My son, he's very sick.

Both historically accurate and on point. A rare combo for the tired "Trolley Problem" gag.
