Playstation controller protocol quirks

22/02/2010 – 01:29

Today I discovered why I have been having a few compatibility problems with my Playstation interface code.
The PSX uses a SPI bus. The device is supposed to put data on the bus when there is a high to low transition, then read the command on the low to high change. Sure enough the official controller [...]

2nd DB9 Connector in the works

25/10/2009 – 19:24

I am doing the code for a 2nd DB9 Connector for the Retro Adapter. It converts the DB15 into another DB9 so you can connect two controllers simultaneously for 2 players.
Atari/Commodore/Sega controllers are working and I will add support for NES and SNES too. I will probably do N64 as well. The button mapping is [...]

Retro Adapter on sale soon and Retro Adapter Wii

06/09/2009 – 17:45

I will be opening the online shop for sales of the Retro Adapter soon (just waiting for the final parts to come in). Both finished adapters and kits will be available, as well as  a selection of connectors.
It occurred to me that I can use the same PCB for a Wii/Gamecube version, so I am [...]

Final Retro Adapter PCBs arrived!

16/08/2009 – 23:36

The final production Retro Adapter PCBs arrived yesterday. I made one up and it works perfectly. I am very happy with the world Seeed Studio did on them, especially considering they are cheap and accept files in Eagle format (so they do all the conversion or Gerber and any panelization etc).

I will [...]

New Retro Adapter prototype PCBs arrived

29/07/2009 – 00:41

Just been updating the <a href=”test”>main site</a> with details of the prototype PCBs that arrived yesterday. The good news is that apart from a couple of minor issues, all is well.

I just need to finish a few things off with the code before doing the first small run of boards,
One issue I have found is [...]

Saleae Logic review

10/07/2009 – 22:01

After a lot of consideration, I decided to get a Saleae Logic logic analyser to help debug my AVR code. There are a few reviews already floating around but little detail on people’s experiences of actually using the thing, so here are mine.
The package is quite nice. You get the Logic, which is tiny, probes [...]

Retro Adapter V2 PCBs arrived!

19/05/2009 – 19:41

The first batch of PCBs is here, and looking good!

Spot the deliberate mistake :) It’s not a problem though, you can easily read the backwards text.

Damn you, SNK and your Neo Geo pads!

12/05/2009 – 14:35

Yesterday was really, really annoying.
I built a prototype of the Neo Geo adapter board. Took about an hour. Plugged it in, realised all the button mappings were wrong. Looked at the 74hc157 datasheet again and noticed that I had connected all the multiplexing backwards. That means the schematic and PCB are both wrong… Built a [...]

Retro Adapter update 11/05/09

11/05/2009 – 14:39

The circuit board designs for the Retro Adapter have been finished and sent off for manufacturing at Seeed Studio. Hopefully everything will be fine and I can then do a larger production run, and start selling kits and finished units.
This is the first PCB I have had professionally made, and the first time I’ve tried [...]
