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.

  1. Hi having lots of problems understanding how TZXDuino works for the Acorn Electron
    I have the very latest firmware 1.11
    Using Kingston Class 4 micro sd card 16gb
    Using correct psu at 6 volts
    Acorn electron and all leads here working correctly
    Micro sd card is formatted for FAT
    I don't know which baud rate to use?
    I don't know if i need turbo mode on or off?
    All files are in zipped format on sd card
    TZXDuino refuses to playing any files allays stuck at 0 with the counter working
    I get error not TZXTape

    Last of all i can't find any real information on the net on "how to use instructions" or user manual

    Please help

  2. If you press the menu key and down you will see the option to turn the UEF turbo mode on or off. On is 1500 baud and off is the baud rate of the UEF which is usually 1200.
    All UEF files must be Unzipped. If you are using Windows you change the file extension of the UEF to ZIP and then use winRAR or winZIP to unzip it. You will end up with a file with no file extension. Add .UEF to the end of that filename and it should work.

    You can find a basic instruction manual at https://mega.nz/#!LAknARQI!CF7EeukEr_w1gnyfB-FwMGrrsygf-b2GTb6CxIJmeco But it is out of date. Updating it is on my to do list but it's getting long atm. Sorry.

  3. I've updated the instructions for TZXDuino for you. I hope this makes it clearer

  4. red button menu screen
    up /down select TSX Baud Rate/UEF Turbo
    play too select UEF Turbo Ctrl
    up/down UEF Turbo Ctrl on/off* (don't know what the star indicates?)
    not sure of the next step too set this?

    red button menu screen
    up /down select TSX Baud Rate/UEF Turbo
    play too select TSX Baud Rate
    up/down TSX Baud Rate on/off* (don't know what the star indicates?)
    not sure of the next step too set this?

    After setting both TSX Baud Rate too 1200 and UEF Turbo off*(i dunno if it's done correctly?)

    Using chain"" then pressing return then selecting file that has uef extension(tried both in caps and small letters seems to make no difference)
    Pressing play it starts to play for less then a second then instantly stops

    I saw two other settings but have no idea how too use or access them because of no instructions

    It's not me being pissy but I've had to guess my way around using the unit because of no real clear instructions

  5. The * indicates which option is selected.

    If the UEF plays for only 1 second then it hasn't been properly decompressed.
    All UEFs are normally in compressed format.
    If it comes in a .zip file you extract it from the .zip and you will get a UEF. You then need to decompress that UEF file again and add .UEF to the end of that file.
    Example
    ChuckyEgg.zip decompressed to ChuckEgg.UEF.
    ChuckyEgg.UEF decompressed to a file called ChuckyEgg.
    Rename the ChuckyEgg file to ChuckyEgg.UEF and it will work.

  6. Okay all good got the files working correctly thanks for your time
    Could please tell me or give more information on the other two menu settings if i need them?

  7. TSX Baud Rate allows you to set the speed of playback of MSX TSX files only.
    The options are 1200, 2400, and 3600. Most files will have difficulty at 3600 and some will only work at 1200. This is because the TSX file type is not as flexible as the standard CAS file for the MSX.

    UEF Turbo Speed is either on or off. It's set to 1500 baudrate in the firmware which is as fast as the Electron can handle. The BBC cannot load UEFs if the Turbo Mode is On.

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…
