Re: Pluggy Reloaded

Just to add to Norgate's reply, here is a snapshot of the settings that you need to setup, (Marcel originally provided this pic).

Re: Issue with building my own Pluppy McPlugface

Have you tried multiple PS2 keyboards? Not all of them are 100% compatible, especially USB keyboards with internal/external PS2 adapters. https://forum.gigatron.io/viewtopic.php?f=4&t=223 https://forum.gigatron.io/viewtopic.php?f=4&t=95 https://forum.gigatron.io/viewtopic.php?f=4&t=62 https://forum....

Re: Raspberry pi loader

Be careful, the Raspberry's 3.3 V inputs are not really 5 V tolerant. The 68R resistors in series with SER_PULSE and SER_LATCH provide some current limitation but they are no level shifters. YMMV. Big oof, I assumed from xbx's original post that the GPIO inputs were either 5v tolerant or 5v inputs ...

Re: Help Sourcing Part

Be careful with using values other than 6.25MHz for the Gigatron's standard firmware, as Marcel took into account the discrepancy between the VGA standard and the Gigatron. A lot of monitors may work fine with crystals slightly out of spec, others may require slight offset/scanning adjustments and o...

Re: Puzzles - A gem matching+smashing game

Sound always adds that extra dimension, it's a really fun game and I like the 5min time limit; it really forces you to try and chain instead of just moseying along.

I've also replaced the old version with this new version in the GT1 repo.

Re: Raspberry pi loader

One question before I start down this path... Is this the easiest/best way to build a loader? I'm trying my best to sift through all the great posts on here and I've seen mention of a SD card loaded?? And also an updated ROM that's in beta. (BTW is anyone here able to burn one of these ROMs for me....

Re: Gigatron ASIC?!?

If this is truly going to be an iterative process with multiple opportunities to add USB at a later date, we could do w/o USB first time through, but no NVM seems like a show stopper. Maybe just have it be a 64kx16 SRAM that loads via SPI each power-up? Coming up with an NVM compiler for this ASIC'...

Re: Gigatron ASIC?!?

So each of the chips comes with a RISC-V on board which is part of the standard harness that efabless would design, so I'm more confident in your ability to port Babelfish over to the RISC-V and do away with the Arduino all together than I am in my ability to slap on an AVR core from Opencores and ...

I was also thinking of writing a python script that wraps the loader and has a mapping of the gt1 files in the github repo. I figured a simple util that can list and load any gt1 by author+name would help make things more accessible.

Code: Select all

./gtRun.py blaknite/puzzles
That sounds like a great idea!
