How to build the circuit boards.

And now on to construction.

For the Nano Circuit board you will need the following

Veroboard (I used a piece 13 holes by 19).
32 DIL Wide Socket.
28 Male Pin Headers.
Jumper wire.

Cut the jumper pins to the following

3 x 1 Pin
2 x 2 Pins
2 x 4 Pins
1 x 6 Pins
1 x 7 pins

Make sure the copper strips on the veroboard are vertical and on the underside of the board.

 When you have soldered all the components flip the board over and remove the copper strips where indicated. Be very careful not to cut yourself.

When completed it should look something like this.












Now on to the Audio filter. You will need the following.

Veroboard (I used a piece 9 holes by 15)
4 x 4.7k resistors.
3 x 4.7nF Capacitors
1 x 100nF Capacitor
3 x Male Pin headers.

Cut your male pin header into single pins.



C1, C2, and C3 are the 4.7nF Capacitors
C4 is the 100nF Capacitor.

Now flip the board over and cut the copper as indicated.

The final assembled board should look like this (minus the wires attached to the pins).













In the next blog we will build the Button board and then assemble all the componants.

New Firmwares With New Features

Thanks to the help of Rafael Molina Chasserot some new features have been added to the TZXDuino and CASDuino firmwares which has freed up some memory as well, which may lead to more features being added in the future.
A percentage counter and a timer counter have been added to all screens so that you know how much is left of a file to play and how long it has taken to load.
The OLED1306 and PCD8544 use completely new routines for the firmwares saving a lot of memory.
Folder navigation is now different. Rather than using the Menu button on TZXDuino or the Stop button on CASDuino to return to the ROOT directory, if you press the stop button when no file is playing you will go up one folder only making it easier to navigate.

TZXDuino
The TZXDuino has had a menu added so that MSX users can set the Baud rate of TSX files so that they can load faster than normal.
A few more emulator only IDs have been fixed so that they are skipped by TZXDuino.

CASDuino
CASduino has had a Baud Rate of 3675 added to…

TZXDuino 1.7

TZXDuino 1.7
This fixes issues with pause lengths that we never noticed before. It should fix games like Top Gun and Street Hawk for the Spectrum and make CDT files behave as they should for the Amstrad CPC.Changes.
*Maximum pause length of 8.3 seconds due to the TimerOne library has been worked around.
*ID20 Pause Block fixed.
*Temporary fix for pause after motor control removed.https://mega.nz/#!aEt1VJKZ!ZFw-fP3bkNTtiPlbG_IllmR94Xni3KvIGUn6Jggfof8

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…
