Etsy Shop

You can go to my Etsy shop and buy my builds of TZXDuino, CASDuino, and ArduiTape with the standard 1602 LCD and coming soon you will also be able to buy the new version with the PCD8544 LCD screen.

CASDuino 1.15

It's been a while since I've updated CASDuino but I've been trying to bring the firmware in line with TZXDuino and ArduiTape to make possible integration of the three firmwares at some future date. The major problem had being getting it to work with the OLED 1306 screen which has now been solved.
Included in this firmware update is a 3rd screen option which is for the PCD8544 which I have also been working on and am now almost ready to share instructions on.

What's New:-
OLED1306 Support
PCD8544 Support
Improved Dragon compatibility
Improved CoCo compatibility (auto run on CoCo games has not been fixed yet but we are working on it.)

You can download the firmware from here.


There are also reports of improved compatibility with the Phillips VG 8020 MSX however as far as I know any incompatibilities were due to a difference in the hardware chipset so how this has happened is a complete mystery but a win I will take.

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

Adding a 5 pin DIN to an Amstrad CPC 464

After mentioning that I had gotten a CPC and attached a DIN to it so that I could connect it to the TZXDuino I have had a few requests on how to do it so I thought I'd try a guide.

You will need to purchase 180 degree 5 pin female din that is chassis mountable.





This is the type that I purchased except mine also had a mounting plate too.
The standard 6128 cassette connector is wired like this.



Each pin is numbered on the back so that you know which one you are connecting it too so don't worry if the pins are in different positions as it depends on whether you are looking from the connection side or the soldering side.


I would use different coloured wiring for each type of connection. I used the following
Ground - Black
Data Input - White
Data Output - Red
Remote Control - Brown

At this point I added 4 male pins to the end of my wiring so that I could build a connector so that I could easily disconnect the DIN should I need to work on the cassette drive.

Next is connecting the wiring to th…

TZXDuino 1.6

Now that I have my CPC464 all set I've been testing .CDT files and have noticed a few issues. The first is that when I altered the code that sped up things for the Spectrum I messed things up for the CPC so that has been rolled back. The second is that with the CPC the motor control and pause after blocks is very important and TZXDuino isn't calculating a long enough pause for some games which causes them to fail. This seems to be a limit to the TimerOne library of 8,191 milliseconds (1F FF). This obviously is a big issue that needs more investigation.

Changes:
*Fixed the garbled text bug (thanks to Rafael Malins Chesserot for that one)
*Rolled back an update that made files load faster on the Spectrum but broke files on the CPC.
*Added a 2.25 second delay on playback after a motor control pause to fix issues with compacted multiload games from http://cngsoft.no-ip.org/cpc_lzx.htm
ToDo
* There is a discrepancy between length of time of pause after block and what the actual p…

Gotten hold of a CPC464

I've finally managed to get hold of a CPC464 so I can see what compatibility is like with TZXDuino.

One of the first things I did was add a DIN so that I could connect the TZXDuino to it. Rather than the normal 5-pin DIN that the CPC664/6128 use I decided that as I already have the cable for the MSX I would add an 8 pin DIN.
After some testing I found the best places to solder the connections and now it is up and running with full motor control.

As there are no TOSEC like downloads for CDT files I have been using both CPCRulez and CPCPower for the downloads.
TZXDuino compatibility is quite good with CDT files although there are a few that use the ID15 block which currently is not compatible but I did notice some issues.
Some games seemed to have insufficient pause blocks and whilst they worked on emulators they did not with either TZXDuino or WinTZX playback. These were quite easily fixed by adding a pause block to the CDT file (Aliens, Ghouls and Ghosts, Turbo Outrun).
Others however …

TZXDuino Firmware Update

TZXDuino user and Luca Forattini has added the ability to load AY files with Spec AY on any Spectrum with an AY chip to TZX.

First you load LOADER.TAP from SpecAY. Once that is loaded just select the .AY file you want to load and away you go.

You can download version 1.5 of the firmware from Here.

You can download Luca's original version of the firmware which is for an Arduino Mega with LCD and buttons shield from Here. Interestingly Luca has added a filesize counter with his firmware so that you can see how large the file currently selected is.
