How to change Firmware on the Arduitape/TZXDuino/CASDuino.




Before you start.
Before starting you will need to download and install the Arduino IDE from https://www.arduino.cc/en/Main/Software

You will also need to install the libraries that are required. You can download them from
https://mega.nz/#!OU0QHbSB!g-LwaCPSBogsWWY-Rtq6-0W1DtJOe3wVFBZre28jIF8
To install these you will need to unRAR the file and copy the folder “Libraries” to the following location on your PC.
C:\Users\[Username]\Documents\Arduino

Now plug your device into your PC using a Mini USB cable and your PC should install the drivers automatically. If it does not then go to the following website for a good howto guide for the correct drivers.

The latest firmware files for your device can be found on the following website.

First time set up.
One you have downloaded and unpacked your firmware you should double click on the .ino file to start the Arduino IDE.

You will need to check that you have the correct board set up.
Go to Tools > Boards and select Arduino Nano.
 
Next you need to Select the correct processor.
Go to Tools > Processor and select ATMega328

Now, with your device plugged in to the PC you need to select the correct port. 
Go to Tools > Ports and select any Port other than Port 1.

If only COM1 shows then your drivers have not installed correctly.

Uploading Firmware
Before you upload the new firmware to your device you will need to check if the LCD settings are correct for your device. Not all I2C interfaces use the same address and for LCDs it’s either 0x27 or 0x3f. For those devices have been manufactured by myself you will find a label on the rear of the LCD with the address written on.
Instructions on how to find an I2c Address can be found here.
http://playground.arduino.cc/Main/I2cScanner

Find the line that says
LiquidCrystal_I2C lcd(0x3f,16,2); and change it to the address you require for your device.

Once that has been done you need to click on the upload button.

You should get a message “Done Uploading” and the new Firmware will be ready to go.

You can download a copy of this from here.

  1. Nice work on the guide. The LCD bit is useful, that is what caused me issues because mine was different.

    Hopefully Santa's Elves will be able to help with the Dragon loading issues :)

    Have a good Christmas.

  2. Unfortunately Andrew is working two jobs at the moment and hasn't been able to devote much time towards the project. Hopefully when things have calmed down a little we'll be able to work on the Dragon/Coco stuff.

    Have a great Christmas and thank you for all your feedback and hard work. Always good to hear from you.

TZXDuino Firmware 1.16, 1.17, and an updated TZXDuino Instruction Manual

  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 v1.2 fo

Latest Firmwares

Whilst it may seem there han't been much going on in recent months we have been working behind the scenes on improving and adding more options to the various firmwares and trying to improve the hardware. The main difference with these firmwares is that OLED 1306 screens are now fully working on all of them and that the PCD8544 has added as a screen option. I will go into the hardware changes needed for that at a later date. ArduiTape 1.5 What's New Added support for the PCD7544. Download from here. CASDuino 1.15 What's New Improved support for CoCo and Dragon Added support for OLED1306 and PCD8544. Download from here. TZXDuino 1.8 What's New Added ID2A Added support for PCD8544 Download from here. TZXDuino 1.8.1 What's New TSX support for MSX TSX files added by Natalia Pujol. Not officially supported and any bugs should be reported to her. Download from here.

And Now For Something Completely Amazing.

 When Andrew Beer and I came up with this idea the intention was for people to build their own and many people have but once in a while someone comes up with something so amazing it really needs to be shared. JamHamster came up with the idea of fitting a TZXDuino in a cassette. Originally it was powered by USB and had a 3.5mm Ear socket but it looked amazing. Then he added a battery so that it was self powered. Then he added a head from a CD to cassette adapter. Then he added a switch under that head so that when you press play on the Cassette Recorder it plays the file you've selected. And the TZXCassette was born Because he is a great guy he's also uploaded the instructions on how to build one to Github and you can download the instructions and build your own. Now at the moment there is no REM control it may not work as well with a CPC 464 as it does with with a Spectrum +2 but it is a stunning piece of electrical engineering and a work of art in my opinion.
