The final steps

The final step is building the Button Board and the connecting everything together.
The Button Board.
For this you will need the following.
Veroboard I use (10 x 20 holes with the copper strips running horizontally)
5 x Buttons.
6 x Right Angle Male Pins.
Jumper wire.

Flip the board over and cut the copper strips where indicated.










Bottom view of the Button Board.


That is most of the construction done. The only things left to do is cut off one end off two dupont wires (for ease make sure one is black) and solder the wires on to the connectors of the 2.5mm port.



ASSEMBLY

This is where it gets complicated. First we will connect the LCD screen to the Nano board.


Use 4 dupont wires and connect to the pins on the back of the LCD screen. The wire on the pin marked VCC goes to a 5v pin. GND to a Ground pin. SDA goes to pin A4 and SCL to A5.

Now the SD Card Slot.










CS to D10
SCK to D13
MOSI to D11
MISO to D12
VCC to 5v
GND to Ground

 Your SD card reader may have it's pins named differently but the pin order is usually the same.


Now to connect the Button Board.
 







I've numbered on the picture where each cable should go on the Nano board. The pin numbered D6 actually goes to D7

The Filter Board and the Amp.
















VCC to 5v Pin on the Nano Board
In to Amp in on the Filter Board
Both GND pins to the Ground Pins on the Nano Board.

On my Amp the is a green socket for two wires that go to the 3.5mm Socket I used a red wire for the in and Black for the GND and soldered the other ends to the 3.5mm socket.

The final piece of teh puzzle is the 2.5mm Motor Control socket. One wire goes to D6 and the other goes to the hopefully final Ground Pin.

The final piece of the puzzle is to programme the Arduino.

  3. Saludos Luis portillo,soy Alfredo Retrocant. Me ha pedido Duncan Edwards que sea portavoz en las consultas y dudas que tengas en el proyecto Casduino. Los autores del proyecto no dominan bien el Español. Ya te envié por mail todo lo necesario para construirte tu propio casduino. Si necesitas mas soporte o ayuda técnica estaremos encantado de ayudarte.

    Recibe un cordial saludo.

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…
