Need Help with Cherry PCB

bpiphany · 09 Aug 2012, 13:58

None of the diodes are hooked up. And that is because in the schematic the pins are numbered 1 and 2. And in the footprint they are "numbered" A and C. I'll work on those Poker details..

This footprint placed at the '~' key position is my take on where the mounting holes goes (nothing confirmed). The USB connector I don't think I've measured out actually.

Yeah, I figured out and fixed the problem with the diodes a couple of hours after I posted the update. I still need to go verify all the components and make sure they're being wired correctly. As for that Poker Mount, is that for the Mini USB connector?

bpiphany · 09 Aug 2012, 20:06

No, those are the screw holes required to attach the PCB to the Poker case.

This looks great, Index. I was playing with bpiphany's example files but couldn't figure out where to fit a teensy, mouting the components individually will make it a lot easier... if not making the soldering more... fiddly... Not to get ahead or anything, but I know you can source the $8 ATMEGA32U4 chip pre-loaded with halfkay from PJRC... not sure where you could source one loaded with LUFA...

bpiphany · 10 Aug 2012, 00:44

The halfkay preloaded chips are sort of a scam =P The tiny size of the bootloader is nice, but that is all there is to it. If you want to change any hardware settings on the chip, like fuses, you erase the bootloader.

All chips come with Atmel's own bootloader from scratch, and the LUFA bootloader can be flashed to the chip with a serial programmer. The stock bootloader should be fine for all purposes though.

Edit: I just want to add that the "scam" lies in their pricing. The chips are ~$4 if you order 25 of them, and those extra $4 for the bootloader is a bit hefty in my opinion.

regack · 10 Aug 2012, 02:21

Thanks for the clarification. I might stick with the Teensy loader since I have some other projects that use Teensys... that said, it's always good to branch out and learn how to use something else... and save some cash for another project.

Don't call it a scam then - if it's overpriced, just tell it like it is.

You may want to look over the switch placements one more time. These numbers are from my favourite spreadsheet.. All numbers are the X-coordinate relative to 'Esc' in your layout.

This is the best I've got on the USB connector. Those are millimetres to the right.

Bpiphany, freaking baller. I'm so close to finishing this (couldn't have done it w/o you), then off to prototyping.

Index · 21 Aug 2012, 01:36

Found a mini usb smt port that I can use with the PCB.

http://www.hirose.co.jp/cataloge_hp/e24000019.pdf

Just need to make a new footprint for it.

Index · 30 Aug 2012, 20:05

Not gonna lie, this project is put on hold for awhile. Why? Because Guild Wars 2. Been waiting for that game since 2006 (or whenever it was first announced).

JBert · 30 Aug 2012, 22:52

Hmmm... I could sure use a new PCB for the Poker, cause it seems I can't wire up a Teensy dead-bug style to the existing one (the pitch of the controller traces is just too crazy to solder wires one by one).

Please let us know if you want to pick it up again.
