Hello Everyone,

This is a quick update so that you guys are aware of the current status, but I won't go into details.

The PCBs and all parts came in late last week. I spent the weekend assembling the electronics and debugging/developing code for the microcontrollers. Both had issues connecting to the PicKit, but I resolved both of those. I got the input controller microcontroller communicating with my laptop over USB. There seems to be an issue with both joysticks that I got in one particular axis, and it seems to be a problem with the joystick itself, but it still needs more investigation.

I screwed up the footprint for the buttons, so I won't be able to fully electrically test them before the next board revision. I can still probe things to make sure things are working properly, so it's not a huge concern.

I'm still working on the software for controlling the LCD driver, so I haven't been able to test that.

I also haven't gotten the battery charging circuitry up yet either. During development I find that having a constant source of power isn't what you want while soldering. I probably won't get to it until I am stuck on other things.

I also just bought a 3D printer! So I'll be able to start working on prototype cases soon. I haven't gotten a shipping notice yet, but I'm hoping to get the printer before the weekend!

Thanks for reading,

Stephen

I like where this project is going, and I can't wait to see it as it gets closer to completion. The only gripe I can think of is the screen being low resolution, at least compared to the HDMI. It should be fine for emulation/gaming, but it leaves a lot to be desired of you're using the X desktop. I scored a seven inch HDMI display for one of my Pi projects, but I think that was the smallest I could find. 

Another thing is why did you choose to use a PIC for the USB multiplexing? I'm sure it's better than just a hub in some way, I just dunno why exactly
