Ooohh you have an inside guy? Ask them when they are going to restock on SOM-128-EXs! I need to buy another 5! Have you tried asking them directly? No need for inside information about restocking current parts! :) I dunno if you reached out to DMP and asked about the SOM-128-EX restocking situation …

Are you having JLC or someone else do the board assembly or do you order bare boards (with stencils)? PCBway, Your Trustable PCB Prototype Partner! (they're my channel sponsor so I kinda have to use them, but they do great work and I get a discount) :D How does assembly work with them? I've been …

That's awesome! Will you be selling any of these pre-assembled? Also - for connecting the box to a computer using PS/2, is there anywhere one can buy male-to-male PS/2 cables...? Yeah I'll probably get a small batch made up. And I found my cables on ebay. male-male ps/2 cables were often used on …

About the button - if you decide to move it to 3.4, you'd still need to keep some kind of way to short 4.6 to ground for bootloader mode, right...? I'll make sure my firmware checks for 3.4 before it does anything else. So 4.6 will only be needed if the firmware gets corrupted somehow. As a last …

Cool! Very interested to know where you land the final pin setup. Also - for my application (using only PS/2, no serial), should I continue to use the BOARD_AXP variant? Are there any advantages to using the BOARD_PS2 one if I change the pin layout on my board? Makes no difference to be honest. …

I can't think of anything else at the moment. As far as I can tell, hidman is now behaving exactly the same as tinyusb. Note that there's now no way to get into the debug mode since I've had to disable the button, but since it always fails at the same point, a simple go/no go test (after verifying …

So it turns out it *isn't* actually crashing when running on a crystal, it's just that WCH in their infinite wisdom decided to make the bootloader switch the same pin as the crystal. So my code thinks you're holding the button so it goes into bootloader mode. If I disable the switch it works great …

Ah well. Might be worthwhile just building my own card to plug in but I bet the concept would work for other chips. I know the SM-750 chips are pretty readily available and have great performance with the SOM based on the video Rasteri did anyway. Since those are already available on cards in the …

Maybe a completely ridiculous thought but I was doing some research on custom built graphics cards, and I came across a few 3Dfx recreation cards that use the VSA-100 chip that's seemingly still floating around out in the wild. Probably not as well stocked as other NOS chips like the CS4237b but I …

Oh bother. I'll have a look over some more LA logs to see what else is different but I'm starting to run out of ideas. I did wonder if maybe the internal clock on the CH559 isn't accurate enough, perhaps I need to add an external crystal. Either way I'd really need access to the keyboard to …
