Restoring Amiga 3000T - Part 7 - Flash Floppy

This is un update about floppy disk emulation.
The H.M. firmware for the gotek floppy is no longer maintained, but Keir Fraser developed a new firmware, FlashFloppy:

https://github.com/keirf/FlashFloppy

FlashFloppy pros:
  • is open source
  • is compatible with a wide range of image formats
  • supports external speaker, rotary encoder and LCD/OLED Displays
Instead of using an usb-to-serial adapter to flash the firmware I tried an USB-to-USB connection.
Gotek USB port can be used to program the microcontroller. You have to set the Gotek in "program mode", connecting the pins as in picture:



Using linux to flash the gotek, you need a tool named dfu-util; on debian like OS run the command:

sudo apt-get install dfu-util

Next step is connect the USB-to-USB cable from PC to Gotek floppy and execute the following commands:

sudo dfu-util -a 0 -s :unprotect:force -D yourflashfloppyfw.dfu
sudo dfu-util -a 0 -D yourflashfloppyfw.dfu

yourflashfloppyfw.dfu is the name of firmware image file provided in the flashfloppy zip package.

When done, reconnecting the gotek to amiga and power on; the lcd display will show 'F-F'.

Build the footswitch (part 2)

The next step is to mount Raspberry, connect gpio pins and solder +5v connection to each button. The first picture shows +5v wiring. I know, I know, the 5v wires are of a different color, but I recycled some wires that I already had. The second picture shows gpio inputs wiring.

Build the footswitch (part 1)

Immagine
I ordered 10 buttons from AliExpress While waiting the delivery of the item, I built a cardboard model of the footswitch and did some test on the placement of the buttons. I had to choose between a button placement on the same line and a button placement on multiple lines. The first option allows easier button selection, but requires a very long pedal board. the first option allows easier button selection, but requires a very long pedal board (longer than 80cm). The second option is more compact (less than 60cm) but requires more attention to select the preset. I chose the latter. I found a 6mm Thick MDF board on sale at a DIY store. This Is the first prototype: 4 presets per row bank down / up on the bottom right

Add more preset selections to Plug

Gone back to Ubuntu laptop and started editing the code. The original Plug software allows to call 8 presets using Keyboard shortcuts. I added 16 more presets and 16 Keyboard shortcuts. Then I though it could be better define 24 presets while using only 8 Key shortcuts.  I added 2 Key shortcuts, 'bank UP' and 'bank DOWN'.  When bank value is 1, presets Key shortcuts allow to select presets 1...8. When bank value is 2, presets Key shortcuts allow to select presets 9...16. When bank value is 3, presets Key shortcuts allow to select presets 17...24. When bank value is 3, pressing 'bank UP' will change bank value to 1. When bank value is 1, pressing 'bank DOWN'' will change bank value to 3. Now I can add instructions to select presets and change bank using some footswitches connected to Raspberry GPIO pins.
