Finally the PCD8544. Almost.

For the last few months I've been talking about how to add the PCD8544 (also known as the Nokia) screen to the devices.
Unfortunately this has not been as easy as I'd first hoped largely due to differences in the screens. Some work well with the standard 5v of the Arduino Nano, others need the voltage in to be 3.3v. Some need resistors others don't. Finally however I can start to write things up properly though.
The software has been written and is fully functioning for a while and whilst there are no improvements in what the ArduiTape/CASDuino/TZXDuino can do, it does use less memory than the other screens and looks a little nicer, in my opinion.
CASDuino Turns Two.
I have been reminded by my Facebook posts that today I completed my first CASDuino specific PP9 build two years ago today.
I used the PP9N Evatron case as I was inspired by one of the TAPuino builds and it's a nice case to work with.
Certain small things have changed since then, button caps, reset switch, different screens, but the basic design of my build has been the same since then.

 Happy birthday to my little monster.

TZXDuino Firmware 1.16, 1.17, and an updated TZXDuino Instruction Manual

  TZXDuino 1.16 In TZXDuino 1.15.3 I added a bug that lowered the volume of some Spectrum TZX files and all ZX80/81 TZX, O, and P files so they didn't work for many people. I fixed this for 1.16. You can download TZXDuino 1.16 from here.   TZXDuino 1.17 The MAXDuino team added ORIC TAP playback functionality to their firmware which I have adapted to TZXDuino. I don't have an Oric Atmos to test it on so I have been recording the playback and loading on Oricutron and everything I have tried has worked. Obviously things may be different on a real machine. Team MAXDuino have also added a speed up function for Oric TAP files which I will add to TZXDuino 1.18 but so far I have been unable to get it to work correctly. You can download TZXDuino 1.17 from here.   And finally there is the updated instruction manual which now tells you how to access Turbo mode for the Electron, ZX80, and ZX81. It also says for Oric but that has not been implemented yet. You can download the pdf of v1.2 fo

Latest Firmwares

Whilst it may seem there han't been much going on in recent months we have been working behind the scenes on improving and adding more options to the various firmwares and trying to improve the hardware. The main difference with these firmwares is that OLED 1306 screens are now fully working on all of them and that the PCD8544 has added as a screen option. I will go into the hardware changes needed for that at a later date. ArduiTape 1.5 What's New Added support for the PCD7544. Download from here. CASDuino 1.15 What's New Improved support for CoCo and Dragon Added support for OLED1306 and PCD8544. Download from here. TZXDuino 1.8 What's New Added ID2A Added support for PCD8544 Download from here. TZXDuino 1.8.1 What's New TSX support for MSX TSX files added by Natalia Pujol. Not officially supported and any bugs should be reported to her. Download from here.

And Now For Something Completely Amazing.

 When Andrew Beer and I came up with this idea the intention was for people to build their own and many people have but once in a while someone comes up with something so amazing it really needs to be shared. JamHamster came up with the idea of fitting a TZXDuino in a cassette. Originally it was powered by USB and had a 3.5mm Ear socket but it looked amazing. Then he added a battery so that it was self powered. Then he added a head from a CD to cassette adapter. Then he added a switch under that head so that when you press play on the Cassette Recorder it plays the file you've selected. And the TZXCassette was born Because he is a great guy he's also uploaded the instructions on how to build one to Github and you can download the instructions and build your own. Now at the moment there is no REM control it may not work as well with a CPC 464 as it does with with a Spectrum +2 but it is a stunning piece of electrical engineering and a work of art in my opinion.
