(OLED I2C Layer, head step irq). Update recommended. ------------------------------------------------------------------------------- 8 August 2022 : Firmware STM32/AT32 USB HxCFloppyEmulator v5.0.0.4a - A new series of Goteks based on the new AT32F435 is now available (PCB "SFRKC30.AT4.35"). This MCU is more powerful than the previous AT32F415 MCU. - The AT32F435 has 384KB of RAM ! (This was 32KB for the AT32F415 and 64KB for the STM32F105) - The AT32F435 can run at 288MHz ! (This was 150MHz for the AT32F415 and 72MHz for the STM32F105) This hardware revision removes the 32KB memory size challenge introduced by the "SARS-CoV-2" Goteks (based on the AT32F415). This is definitively more reliable because file system cache can be properly implemented to deal with the USB stick latency. I strongly recommend this new AT32F435 Goteks hardware revision. Regarding the HxC firmware the new v5 version is now compatible with this new core. It still compatible with the STM32 and AT32F415 Goteks. - Others changes: - Artery AT32F415 Gotek now runs at 144MHz ! (the v3 & v4 run this core at 72MHz) - Many changes and some fixes in the low level layers. - The bootloader was updated too and finally gain the OLED screen support. - The offline firmware installation (activation at hxc2001.com) now supports this new core. - The online serial installation doesn't support yet this core.

Since March/April 2021 we can see some new Gotek variants on the market. Due to the electronic components shortage, these new Gotek revisions use different MCUs. The STMicroelectronics STM32F105 MCU was replaced by Artery MCUs : AT32F415RCT7, AT32F415CBT7,... These MCUs are "mostly" compatible with the previously used STM part but there is an important difference : The RAM size. While the STM32F105 offers 64KB of RAM, these Artery parts have only 32KB of RAM. These changes imply modifications in the firmware. A first HxC Firmware compatible with the AT32F415RCT7 MCU can be found in the Artery_AT32_Gotek_HxC_Firmware folder. Others changes : - The bootloader was updated this week to support all the 3 Gotek variants : STM32F105RB6, AT32F415RCT7,AT32F415CBT7. - The bootloader now supports GPT/GUID formatted USB sticks. - The server was updated this week to support all the 3 Gotek variants : The bootloader can installed on all these Gotek using the normal online procedure : https://hxc2001.com/docs/gotek-floppy-emulator-hxc-firmware/pages/bootloader-installation.html More details on the forum : https://torlus.com/floppy/forum/viewtopic.php?p=23695#p23695 ------------------------------------------------------------------------------- 29 March 2021 : Firmware STM32 USB HxCFloppyEmulator v3.6.1.2a - Preparing the firmware for the next releases / features : Important code size optimizations. (First round !) - OSD : The HSYNC polarity can be set on the custom firmware page : https://hxc2001.com/custom_fw/.

Mount USB stick's FAT12 partitions ! The HxC Floppy Emulator firmware for Gotek and clones drives is now able to emulate floppy disks directly from the USB Stick partitions. This mean that you can now easily exchange files without the need of any floppy image with machines supporting the common DOS/FAT file system. In Image-less mode Windows/Linux/macOS operating systems are able to mount automatically the floppy disks partitions and let you access to the floppy disk files. All floppy disk partitions size is supported : 720KB (DD), 1.2MB (HD), 1.44MB (HD) and even non standard sized disks (2.5MB and more...) -- How to prepare the USB stick ? -- You need to prepare the USB stick to use the Image-less mode. Some USB stick files are available in the Image_Less_Mode folder in the firmware archive. You can write them with rufus or dd or any other tool. The firmware is supporting 4 different partition types / usb stick "format" : - GPT partitioned USB stick : This format allows you to have up to 128 floppy disks/partitions on the USB Stick. This is supported by all current operating systems (Windows 10 and recent versions of macOS and Linux). Pre-partitioned USB stick GPT images are available in the Image_Less_Mode folder. - MBR partitioned USB stick : This format allows you to have up to 4 floppy disks/partitions on the USB Stick. This is only recommended if you are working with old operating systems. (Windows XP...) Pre-partitioned USB stick MBR images are available in the Image_Less_Mode folder. You can write them with rufus or dd or any similar tool. - "No partition" USB stick : This format allows you to have 1 floppy disk per USB Stick. This is supported by all opertating systems. You can write any DOS compatible floppy image with rufus or dd or any similar tool. - Original Gotek firmware "Batch Manage Tool" formatted stick : The HxC firmware is now compatible with the original Gotek firmware tool "Batch Manage Tool". So you can now use this tool to prepare and access the USB stick partitions. The firmware recognizes automatically how the USB stick is prepared. No particular action is needed on the emulator. Please note that the classic floppy images modes still of course supported. ------------------------------------------------------------------------------- 21 August 2020 : Firmware STM32 USB HxCFloppyEmulator v3.4.18.1a - USB Stick : GUID Partition Table (GPT) support.

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 ;). https://hxc2001.com/download/floppy_drive_emulator/HxCGotek_OSDAmiga1.jpg 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.

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_drive_emulator/HxCGotek_voltage_system_monitor.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". ------------------------------------------------------------------------------- 10 June 2019 : Firmware STM32 USB HxCFloppyEmulator v3.2.3.1a - 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.

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. ------------------------------------------------------------------------------- 1 May 2019 : Firmware STM32 USB HxCFloppyEmulator v3.1.60.5a - GeneralMusic S2/S3 : Undocummented floppy format support added + *.gem file extension support. - Non-gated interface : Ignore the floppy selection line for the head step + Some fixes. ------------------------------------------------------------------------------- 28 April 2019 : Firmware STM32 USB HxCFloppyEmulator v3.1.60.2a - Motor-ON signal support to emulate properly the "READY" and "INDEX" signals. See the https://hxc2001.com/custom_fw/ to select the input line and tweak the timings. - OLED : SSD1305 2.23" 128x32 OLED screen support added. - Internal enhancements. (WIP) ------------------------------------------------------------------------------- 12 April 2019 : Firmware STM32 USB HxCFloppyEmulator v3.1.48.1a New direct raw format support : - Yamaha QX3 format (*.IMG,*.DSK) 7 segments screen menu : Add missing system family entries : 15 = Robox RC9400 16 = Kawai 17 = Yamaha QX3 18 = User defined format ------------------------------------------------------------------------------- 11 April 2019 : Firmware STM32 USB HxCFloppyEmulator v3.1.47.1a - New option : Hide the files extensions on the OLED/LCD screens. ------------------------------------------------------------------------------- 29 March 2019 : Firmware STM32 USB HxCFloppyEmulator v3.1.46.1a ( -> In the "Diagnostic_Firmware" Folder and https://hxc2001.com/custom_fw/) - Gotek I/O Lines Diagnostic/Test mode Since this hardware is quite sensitive to ESD and other electrical issues, the floppy lines can be easily damaged. This new mode allows you to test/check all Gotek's Input/Output lines with a simple wire. The test must be run with floppy ribbon disconnected from the machine. Once enabled/flashed with the diagnostic firmware, all outputs will toggle every 2 seconds. All inputs states are displayed on the screen. -> Input lines test method : The default input states should be High (1), so to test an input line you have just to connect it to the ground/vss. On the floppy port you just need a jumper to make a contact between the line and the ground. Once the jumper is placed between the line pin and the ground/vss pin the corresping input state should turn to Low (0). -> Output lines test method : All outputs are toggling every 2 seconds during the test. (Note : A 1 ms pulse is sent to the JB output at each toggle to test the buzzer ouput) Connect the output line to test to one input line (use a tested input by the above method) with a simple wire. If the corresponding input status is toggling with the outputs line, then this means that the output line/driver is working properly. -> LCD / OLED / 7 segments screens output/input status definition : LCD/OLED input lines status format : "IN:123456 789AB" 1 or Digit-1-segment-a : Floppy Drive Select line (Pin 10 or 12 or 16 -> Depend on the S0/S1/MO jumper !). 2 or Digit-1-segment-b : Floppy -Direction In (Pin 18) 3 or Digit-1-segment-c : Floppy -Step (Pin 20) 4 or Digit-1-segment-d : Floppy -Write Data (Pin 22) 5 or Digit-1-segment-e : Floppy -Write Enable (Pin 24) 6 or Digit-1-segment-f : Floppy -Head 1 Select (Pin 32) 7 or Digit-1-segment-g : Down push button (left) 8 or Digit-2-segment-a : Up push button (right) 9 or Digit-2-segment-b : Select push button (JA) A or Digit-2-segment-c : Rotary CK (J7-2) B or Digit-2-segment-d : Rotary DIR (J7-1) 7 Segments Digit-3 : 'h' when the outputs are high and 'L' the outputs are low. 7 Segments Digit-2-segments e,f & g : ON when the outputs are high and OFF the outputs are low. -> Floppy connector pinout : Pin Signal Pin Signal 01 Ground (O)02 -High Density Select 03 Ground 04 Reserved 05 Ground 06 Reserved 07 Ground (O)08 -Index 09 Ground (I)10 -Drive Select 0 (*) 11 Ground (I)12 -Drive Select 1 (*) 13 Ground 14 Reserved 15 Ground (I)16 -Motor Enable (*) 17 Ground (I)18 -Direction In 19 Ground (I)20 -Step 21 Ground (I)22 -Write Data 23 Ground (I)24 -Write Enable 25 Ground (O)26 -Track 0 27 Ground (O)28 -Write Protect 29 Ground (O)30 -Read Data 31 Ground (I)32 -Head 1 Select 33 Ground (O)34 -Diskette Change/Ready (*)Depend on the S0/S1/MO jumper! -> 7 segments screen segments definition : // a // f b // g // e c // d - Fake/Pre-April Fools "Side 0 tracks file opposite order" option removed from the front page. ;) ------------------------------------------------------------------------------- 26 March 2019 : Firmware STM32 USB HxCFloppyEmulator v3.1.45.2a *-----------------------------------------------------------------------------* EDIT/NOTE : This release was a fake release with a nonsense feature.

This one can be used with many types of machines). ------------------------------------------------------------------------------- 17 June 2015: Firmware STM32 USB HxCFloppyEmulator v3.0.4.0a - I2C LCD auto detection/scan and communication improved/corrected - Low level pulses generator improved : - Code size reduced. - 250Kbits/s, 300Kbits/s, 500Kbits/s support (FM/MFM). - Variable bitrate & flakey bit support "Ready" ;) ------------------------------------------------------------------------------- 07 June 2015: Firmware STM32 USB HxCFloppyEmulator v3.0.3.1a - Some IOs timing improved. - Agony game issue almost corrected. ------------------------------------------------------------------------------- 06 June 2015: Firmware STM32 USB HxCFloppyEmulator v3.0.3.0a - USB Sticks are now mounting a way faster at power up ! :) - I2C LCD display support added ! These kind of I2C LCD board is compatible with the firmware : http://www.ebay.com/itm/IIC-I2C-TWI-SP-I-Serial-Interface-Board-Module-Port-For-Arduino-1602LCD-Display-/310565362720?pt=LH_DefaultDomain_0&hash=item484f235c20 (board only - without the LCD) http://www.ebay.com/itm/IIC-I2C-TWI-SPI-Serial-Interface-Board-Module-Port-for-Arduino-1602LCD-Display-/161245616356?pt=LH_DefaultDomain_0&hash=item258afcd8e4 (board only - without the LCD) http://www.ebay.com/itm/New-Blue-IIC-I2C-TWI-1602-16x2-Serial-LCD-Module-Display-for-Arduino-/221439853893?pt=LH_DefaultDomain_0&hash=item338ed80545 (board + LCD) http://www.ebay.com/itm/IIC-I2C-TWI-SP-I-Serial-Interface1602-16X2-Character-LCD-Module-Display-Yellow-/310565065933?pt=LH_DefaultDomain_0&hash=item484f1ed4cd (board + LCD) Any I2C address is supported : The firmware scan automatically the I2C bus at power up (0x20-0x27 and 0x38-0x3F address range scanned) So there is no specific requirement about the I2C address setting. To connect the I2C LCD, you have to connect SDA & SCL at the J7 connector (see below). Please note that 2 additionals 4.7Kohms pull up resistors (+5V) are needed on SCL & SDA. the +5V and GND wire can be connected on the programming connector (see below) : If you want to build the I2C board yourself, here is the schematic: https://hxc2001.com/download/floppy_drive_emulator/Ext_Slim_HxC_Floppy_Emulator_I2C_LCD_Schematic.pdf - Possible +5V source on the PCB (on the programming connector): _____________________________ | -+--- NC -+--- GND O J3 (BOOT0) -+--- GND O VCC3V3 -+--- +5V OO TX | +5V OO RX | GND OO RST |-- | | | | - SCL & SDA position on J7 : _____| | | | USB | |_____| OO______________________| SDA OO|SCL GND OO|VCC3V3 J7| | __________| ------------------------------------------------------------------------------- 31 May 2015: Firmware STM32 USB HxCFloppyEmulator v3.0.2.5a - CPC & Shugart disk change signal timing corrected. - Dead lock issue while existing the direct access mode corrected. ------------------------------------------------------------------------------- 23 May 2015: Firmware STM32 USB HxCFloppyEmulator v3.0.2.2a - Amiga Disk change timing corrected.
