Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

You've all been very patient, and I've not been exactly fast in sorting out the docs. I hope this has been worth waiting for. :)

Incidentally, the USB-A socket now gets it's power from the barrel jack input only. If you want to use it to power a VGA-HDMI converter or to charge your phone then you will now need a suitable lead (unless you hack the PCB, of course).

Thanks Mick,

I will order myself some as soon as you tell us what the canonical PCB colour for the PicoGAME 2.0 is going to be ?

As opposed to what ?

Best wishes,

On the schematic, when you refer to changing out C9 for a 100uF Capacitor when using an SD card versus a microSD socket... I assume you mean C15 and forgot that a renumbering happened since C9 is now in the Audio Filter section.

Hmmm... colour... It's completely up to you. :)  I was going to order blue again personally, but that's only because I have a blue case here. Do you fancy black? Maybe with gold copperwork instead of HASL (or whatever the name is - if they don't charge extra)? It might look kinda cool for those who don't want cases.

I've just thought - I think there are pillars in the top and bottom of those cases. You could house two "topless" boards in one case. :)

Previously it didn't matter how the 5V was derived, the USB-A was connected. Now there is the option to power the entire board from the PicoMite's USB connector. In that mode you can't (officially) use the USB-A output.

Well I've pulled the trigger on 5 in black for very little money - though not with the gold copperwork as that is a lot more expensive.

Thanks Mick,

An error in the documentation:

The BOM refers to the PCB as "PicoGAME PCB (version 1.5)"

All errors and omissions will be logged in my foggy memory and hopefully get fixed in the near future. :)


Wow... an extra $17 for the gold finish. I don't think I'll bother either. :)

Hi Mick,

Can I upload the latest construction pack to the Wiki ?

What's the position with regards the PicoGAME Mini construction pack, you asked me to hold off on putting that on the Wiki, is that still the case ?

Best wishes,

Tom

Ideally I'd like to hold off any of the PicoGAME stuff until someone has built one and found any major bugs for me. :)  Once I've had a chance to correct the silly errors there's no problem. I don't think inflicting buggy designs on the world in general is too good. That's for the commercial stuff. ;)

You could put "Coming Soon" notes on there about any new designs if you like, possibly with a brief description and maybe a link to the forum. If people want to build them then they are welcome to, but they have to understand that they may come complete with "unknown features". lol

Hi Mick,

Sorry to resurrect an old thread, but I never put together my PicoGAME 2.0 so am still using the 1.4.

IIRC the capabilities of Port B on the 1.4 are different to those on the 2.0 ... something to do with not supporting the Atari joystick ? I may have asked before, but is it possible to bodge the 1.4 board to make it compatible in this respect - save me the time and components for building up a 2.0 ?

Best wishes,

Tom

Port A supports the Atari joystick?

  Constructors Notes said  Two Controllers can be used, or one joystick. If a single Controller or Joystick is used it will normally be in Port A. Port B can be used for a second Controller, a Paddle/potentiometer or for simple networking.


It looks like it would be a bit messy to make port B joystick capable.

Bill

Edit: Mick is usually fast to respond. Hope you are well Mick.

Yeah, I'm fine thanks. Just got carried away with the aquarium, an electricians forum and life in general.  :)

Right, to get 2 Atari joysticks on PicoGAME 1.4...
There is no connection on pin 1 so no "up" direction, but this can be got around. Link pin 1 to pin 9. This now gives:
Up - GP28
Down - GP4
Left - GP5
Right - GP22
Fire - GP15

You will need to set LB1 LH link to UP to turn on the pullup for GP28.

The pullup on pin 3 is a bit weak. If you have problems with Left then it might be an idea to connect a 22K resistor in parallel with R21 to give around 10K pullup like the other pins. If you do that then you could link out R20. The other components around there (R18, D4 and D5) will be doing nothing and can be ignored.

It's a completionist thing Bill, I want to check that my code supports both.
