ArduiTape/CASDuino/TZXDuino - The cassette player replacements

  TZXDuino 1.16 In TZXDuino 1.15.3 I added a bug that lowered the volume of some Spectrum TZX files and all ZX80/81 TZX, O, and P files so they didn't work for many people. I fixed this for 1.16. You can download TZXDuino 1.16 from here.   TZXDuino 1.17 The MAXDuino team added ORIC TAP playback functionality to their firmware which I have adapted to TZXDuino. I don't have an Oric Atmos to test it on so I have been recording the playback and loading on Oricutron and everything I have tried has worked. Obviously things may be different on a real machine. Team MAXDuino have also added a speed up function for Oric TAP files which I will add to TZXDuino 1.18 but so far I have been unable to get it to work correctly. You can download TZXDuino 1.17 from here.   And finally there is the updated instruction manual which now tells you how to access Turbo mode for the Electron, ZX80, and ZX81. It also says for Oric but that has not been implemented yet. You can download the pdf of v...

New firmware . TZXDuino 1.15.3 Adapted the MAXDuino ID19 code and TurboMode for ZX80/81. To access Turbo Mode for ZX80/81 and Electron please switch Turbo Mode On in the menu Also added UEF Chunk 117 which allows for differing baudrates in BBC UEFs. Added a Spectrum Font for OLED 1306 users converted by Brendan Alford. Option added to userconfig.h Added File scrolling by holding up or down buttons. By Brendan Alford. Download from here. CASDuino 1.24 Added a Spectrum Font for OLED 1306 users converted by Brendan Alford. Option added to userconfig.h Added File scrolling by holding up or down buttons. By Brendan Alford. Download from here.

I hated the method of using the menu to switch ID15 on and off so I've managed to fix it to an automated system to keep things as simple as possible for the user. You can download the latest version from here.

TZX Block type ID15, bane of my existence when it comes to TZXDuino I found, with the help of users, that enabling ID15 screwed up many other TZX files that used to work under 1.13 on the MSX and Spectrum. To fix this I've added yet another option to the Menu. It's not how I would like to have done it but it works. If you're not trying to load a musical loader or a Direct Record (usually a Firebird game) on an Amstrad CPC then switch ID15 off. There are very few TZX files for the Spectrum that use ID15 and so far there are no TSX files for the MSX that use ID15. Also please make sure you turn the Gremlin Loader off as well as that can also stop files loading properly. Turn these options on separately if a file fails to load. IF after that it still fails then please let me know the file, where it's from, and what computer you are trying it on. TZXDuino 1.14.2 can be downloaded from here.

It's been a while since ~I've added anything new to the blog I have been still working on the project. TZXDuino 1.13 I've updated the TZXDuino firmware to include HQ.UEF support which was programmed by Rafael Molina Chesserot of the MAXDuino Team. Most unzipped UEFs will now work with the TZXDuino on both Electron and BBC. The only exceptions I've found so far are Uridium and Starquake on the BBC. Because the TZXDuino is now working on so many other models of computer and not just the Sinclairs I've added a Pause at Start option to the Menu. With this on, when you select a file and press play the file will be automatically paused unless you have typed in your load command on your computer and pressed enter and the motor control is plugged in. It's exactly the same way a cassette player with motor control would work. You can download the firmware from here. New Software Speaking of UEFs Ricky El-Qasem has made a UEF extraction tool that makes it so much more ...

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 3...

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.

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 ...

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 howe...

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. You can watch a video of Luca's TZXDuino at work here.

It's been a while since I've published anything on my progress on converting things to the Maple Mini so I thought I'd keep you up to date. I have converted TZXDuino to the Maple Mini and it is working but not properly. For some reason, even though it is using the same values as the Nano the frequency of the output is higher. So much so that fastloaders cannot be recognised and TAP and simple TZX cannot all register with the Spectrum. Oddly this would indicate that a microsecond for the Maple Mini is different to the microsecond for the Arduino Nano, yet the files play for a similar length of time. It's all highly confusing and I've put the project on the back burner for a while so I can concentrate on working any errors out of the CAS/TZXDuino Shield PCB. The good news being that when I was trying to figure out what was going wrong I noticed that TZX2WAV which we had been using as a benchmark to test our coding actually has a typo in it a decodes slower than the TZ...

ZX81 P and O filetypes have been added to TZXDuino. There is also a minor speed update that shaves a few seconds off previous load times. https://mega.nz/#!Ldkn3Q7L!hOjJVTZZQcRulmDdmVB19HxA04mFa9oAKAsEmrDD2qk We were hoping to have an update to CASDuino with working Dragon CAS files but unfortunately whilst we can get Chucky Egg to work we still can't get others to work. We are still working on it though.
