Sorry for cross-posting, but I'm interested in the HxC firmware and would like to understand how the bootloader license works. Am I correct if I assume it can be installed on the same Gotek device as many times as I want/need?

If I purchase HxC and use it on a Gotek device but then decide to switch back to FlashFloppy, can I at a later point re-install the HxC bootloader (on the same Gotek device) that I purchased?

[Jeff_HxC2001]

There are tons of updates since the last time i posted here.

Here is the last one :
(Check the releases notes for the previous releases.)

5 May 2019 : Firmware STM32 USB HxCFloppyEmulator v3.2.1.1a ( -> In the "WIP_Firmware" Folder and https://hxc2001.com/custom_fw/ )

- New major feature ! : Auto mount USB stick folder to a FAT/DOS compatible virtual floppy !

This feature allows you to directly put your files in a stick's folder and mount this folder as a FAT/DOS floppy disk !

You can use it with any machine compatible with the FAT file system (PC, Atari ST, lots of keyboards/samplers and CNC machines...).

To use this feature, copy an empty/preformatted DOS IMG image to the stick path "/mount/emptyfat.img"
This image can be a 720KB or 1.44MB blank DOS image or any other FAT compatible blank image.
You can use the HxC Floppy Emulator software Disk Browser to create it or take the ones present in the firmware archive.

Once you select a "mount source" folder on the emulator, the emptyfat.img file is duplicated to a "MOUNTED.IMG" file.
Then all files/subfolders present into the selected folder are added into this duplicated image.
(Note : the emptyfat.img remains untouched).

Your "mount sources" / root folders should have the extension ".mnt" to be mounted by the emulator :
example : "myvirtualdisk.mnt"

This new feature can be used with the "normal"/direct browsing (oled/lcd screen usage) and indexed modes.
For the indexed mode just put the DSKAXXXX prefix in the mount point folder name.
example : "DSKA0000_MyMidiFiles.mnt"

Please note that the image duplication and files copy operations can take some seconds.
I will try to optimize/speedup the mount operations in the next releases.

Let me know if you have any problems or any suggestions/questions/comments on the HxC forum or by email.

- FAT 12/16/32 layer write support enhanced to create entries (files & folders) and allocate clusters.

- New major feature ! : Auto mount USB stick folder to a FAT/DOS compatible virtual floppy !

This feature allows you to directly put your files in a stick's folder and mount this folder as a FAT/DOS floppy disk !

Wow, this is a really interesting major update!
Question: When I "eject" the MOUNTED.IMG, are the files copied back to the source directory on the USB stick? Or is this a one-way operation?

[Jeff_HxC2001]

17 May 2019 : Firmware STM32 USB HxCFloppyEmulator v3.2.1.2a ( -> In the "WIP_Firmware" Folder and https://hxc2001.com/custom_fw/)

- Fix the files extensions display option : you can now also hide the file name extensions in selector/indexed mode.

22 May 2019 : Firmware STM32 USB HxCFloppyEmulator v3.2.2.1a ( -> In the "WIP_Firmware" Folder and https://hxc2001.com/custom_fw/)

- HFEv3 : Weakbits support added.

10 June 2019 : Firmware STM32 USB HxCFloppyEmulator v3.2.3.1a ( -> In the "WIP_Firmware" Folder and https://hxc2001.com/custom_fw/)

- On-die STM32 temperature sensor support : You can get the current CPU core temperature from the embedded menu :
press both buttons to enter the menu. Choose "temperature" or "E " if you have the original 7 segments display.

- Blackberry trackball : Sensitivity reduced/better usability.

12 June 2019 : Firmware STM32 USB HxCFloppyEmulator v3.2.4.1a ( -> In the "WIP_Firmware" Folder and https://hxc2001.com/custom_fw/)
- Power supply voltage measurement :

You can now see/read the power supply voltage incoming to the floppy emulator.
This feature is quite useful to check the machine power supply state/working condition.
If you want to use this feature you must add this voltage divider to measure
the power supply on the JC jumper input :

VSS/GND|---| 1Ko Resistor |--(JC pin)--| 4.7Ko Resistor |---< 5V Power Supply input.
(See https://hxc2001.com/download/floppy_dri ... onitor.jpg)

Notes :
- Use +/-1% Resistors if possible.
- This voltage divider support up to 18V.

Use the embedded menu to access the system monitor :
Press both buttons to enter the menu. Choose "System Monitor" or "E " if you have the original 7 segments display.

- "Temperature" menu renamed "System Monitor".

20 June 2019 : Firmware STM32 USB HxCFloppyEmulator v3.3.1.1a ( -> In the "WIP_Firmware" Folder and https://hxc2001.com/custom_fw/)

New major feature ! : On screen display support (OSD overlay)

The HxC firmware for Gotek now support the On Screen Display !
You can now select images and see the drive status on the machine's screen without any additional software or LCD/OLED !
No need to make holes in the machine case anymore .



You only need 2 wires and a resistor to connect the Gotek to the machine's video signals :
One wire is used for the CSYNC video signal (Composite Sync), the other wire for the red, green (prefered) or blue signal.

One resistor must be put in serie on the color signal between the Gotek and the machine.
You can use a value between 220 and 470 ohms for this resistor. A potentiometer can be also used to tune the OSD brightness/contrast.

This was currently tested on Amiga 500, Atari STE and Amstrad CPC 6128 machines, but should work with any machines having a composite sync signal.

HxC Firmware for Gotek OSD wiring

Gotek wiring :

OSD Video CSYNC in : Amiga 500 U41 Pin 8 -> Gotek "JTCK-SWCLK" pin (PA14) (near the serial tx programming pin, please see picture).

Custom HxC firmware

[tzok]

OSD works great, but only in ST LOW/MED. Technically it could be connected to MONO out, but either to MONO or to COLOR. It also supports separate H+V sync signals, what is not stated here.

OSD works great, but only in ST LOW/MED. Technically it could be connected to MONO out, but either to MONO or to COLOR. It also supports separate H+V sync signals, what is not stated here.

You need to enable these options. separate H+V sync signals are supported, just rebuild the firmware with the options enabled :

[czietz]

Sorry for reviving this old thread, but I think the following might be of interest to other people. I recently helped someone connect the OSD option in an STE with modulator. (The photo in the post above https://www.atari-forum.com/viewtopic.p ... 19#p376919 is for a French(?) STE without modulator.)

The solution - confirmed to be working - was to take the CSYNC (composite sync) signal from pin 2 of the MC1377 IC.
