The MSF signal is a bit of a mess

28/07/2010 – 00:06

I am working on another clock, this time with MSF (Rugby/The time from NPL)  radio time setting. I know, I need to document the last one… Anyway, I finished the decoder today. The MSF signal is frankly a mess. Things seem to have been added and then removed over the years. There are four different [...]

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 [...]

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 [...]

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 put together [...]

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 [...]

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, [...]

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.
