TZXDuino v1.0

TZXDuino has moved out of Beta and is in it's first release version.
Little has changed from v0.8beta3 except extra motor control for Amstrad CPC .CDT files.

TZXDuino v1.0

The files can also be found on GitHub


  1. I am very excited that you got the spectrum tzx files to work. Today I tried to build your project using and arduino mini, somehow all I get is a 1 line of solid blocks on the display. Am I doing something wrong (I checked all connections twice)?

  2. I see now, I had to change the lcd settings to "LiquidCrystal_I2C lcd(0x27,16,2)" for a 2 line display. Now I get a correct display, just tells me no sd card at this time, so have to fix that but making progress :-)

  3. Excellent. I was about to say it sounds like the lcd settings, usually it's the address.

    There may need to be some pin changes for the buttons with the Mini. I know I have tried the Pro Micro with a few changes but I'm not sure about the Mini though.

  4. I didn't hook up the buttons yet, first wanted to get it to run, so working on the sd card now first. I'm limited in time so I will have to see when I can fiddle with it again.

  5. I'm going to guess at the following

    10 SDCS
    11 MOSI
    12 MISO
    13 SCLK

    The Pins for the buttons might be the same IF you have the LCD attached to pins 2 and 3

  6. I got my Arduitape recently and the question is that I don't see any tutorial or FAQ about the correct use of the mounted and cased unit. Are you going to publish something like that for beginners , and giving more emphasys in the buttons' functions, SD card types (if they need a special format before using them), plug-ins, USB connection, firmware update, how to load files in any specific computer (ZX Spectrum, Amstrad, MSX, etc.)... everything?

    1. Yes. I'm working on an instruction manual and tutorials etc.

      Sd cards use FAT file format. As for classes I would recommend Class 4 upwards if you are using an MSX and want to load at the 3600 baud rate but with a word of caution. Not all Class 4s are created equally and some games (Elite and Aliens for example) will end with a checksum error but only at 3600.

      In the meantime if you have any questions please do not hesitate to ask.

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.

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 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.!aEt1VJKZ!ZFw-fP3bkNTtiPlbG_IllmR94Xni3KvIGUn6Jggfof8

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.
