UEF Playback added to TZXDuino

Thanks to the work of Kernel Crash we have added uncompressed UEF playback to TZXDuino. This means that Acorn machines can be added to the list of computers that can use TZXDuino. There is standard mode and a Turbo mode that can be switched on in the menu. The turbo mode loads at 1500 baud and does improve the loading time on an Acorn Electron. There is also a 1550 and 1600 option in the TZXDuino.h file but not all Electrons can handle the faster speed.

You can read Kernel Crash's blog here.

You can download the TZXDuino 1.11 from here.

Trying to make firmware editing more user friendly.

The more I build and try to improve on the various firmwares I've realised that it's not entirely friendly for new users to edit their firmware for their version of device. In an aim to correct that I have added userconfig.h to the various firmwares.
This is just a little settings file that users can change without fear of harming the main programme.
It allows you to set which screen you are using and in future which startup logo for some screens and maybe other settings.

How to use.
At the moment the userconfig.h looks like this

/*                                                             */
/*                                                             */
/*          Configure your screen settings here                */
/*    Delete the // of the lines appropriate to your device    */
/*                                                             */
/*                                                             */

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, diffe…
