Usb Floppy Emulator' title='Usb Floppy Emulator' />Thanks for your understanding. Some time ago i bought one of these very low cost USB floppy emulator from ebay to play some ADF files on my Amiga. Floppy To Usb Software' title='Floppy To Usb Software' />Gotekusbbatchfiles Some batch files for extractingupdating images made from Gotek floppy drive emulators. Unfortunately these drives was unable to supportemulate the Amiga sectors encoding scheme and couldnt work on Amiga computers But now all of this is pastAfter some hours of coding the the Gotek firmware can now be replaced by an Amiga compatible firmware. This firmware allows to load any ADF file present on the USB key and play it on the Amiga A special boot ADF file allows to select the game or demo to start. The Gotek Floppy emulator working on an Amiga 6. State Of The Art Demo Actual main features of this firmware Read Write 8. KB ADF Files. USB Key support. FAT1. FAT1. 6 FAT3. Subfolder support. Amiga software to select the ADF files on the USB key. Tested on A5. A6. Should work on all Amiga. HOW TO USE IT  This is quite simple You have just to copy all your favourite ADF files on the USB Key. On the Amiga you can select the ADF files thanks to a special ADF file SELECTOR. ADF. Once done the Amiga restart on the first image selected. In the actual version you can select up to 3. By this way multi disks games can be played without problem. The 7 segments display on the emulator shows the actual disk number selected. You can change the disk with the two buttons present on the front of the emulator. To start again the special ADF you have just to select the position 0. Amiga. The menu appears in less than 1. In the software you can use the joystick or the arrows enter at the keyboard to choose the images and save the selection. WHERE TO GET THIS EMULATOR The Gotek floppy emulators can be found everywhere. Since all Gotek drives are based on the same hardware, any version should be compatible. For reference i got the drive for 2. Euros3. 3 Shipping included on Ebay Link to the Ebay page hereI also bought a different model, without the 7 segments display buttons from another place to check if there is some differences. There is no difference and the firmware is working on both models without any modification. OK I HAVE THE EMULATOR, HOW TO  TRANSFORM  IT To do this you need Any serial RS2. V TTL adapter or USB to serial cable. I used an FTDI TTL 2. R 3. V3, but anything providing a 3,3. V signal level is ok. TX RX support is enough to reflash the MCU no hardware handshake needed. Some places to get this kind of cable   https www. EDIT Since the STM3. V tolerant, a 5. V version of the cableadapter should be fine too. The progamming port can be found at the rear of the emulator. Most of time you dont even need to open it Here is the list of connections to do Connect BOOT0 to 3. V This will put the device in programming mode at power up. Connect TX to the RX wire of the 3. V serial cable. Connect RX to the TX wire of the 3. V serial cable. Connect VSS to the ground wire of the serial cable. Connect the 5. V to a 5. V source. I just used the 5. V coming from the FTDI cable. Note The above picture shows you the actual pinout of the programming port, not where to plug the wires Dont forget to cross connect the TX and RX lines between the adapter and the usb drive adapter TX on USB drive RX and adapter RX on USB drive TX. Once done, connect the cable to the computer and start the Flash Loader Demo software. Select the right COM port and press Next. NOTE 2. 60. 21. If you have some difficulties to make the connection between the device and the software, you can try to issue a reset to the emulator. To do this connect during 1 second the  RST  signal present at the right of the RX signal  to the ground. Dont disconnect the RXTX Power wires during this operation. Once done start again the software. Also to make sure that your serial adapter is working correctly, you can try a loopback test use a terminal software and connect the rx tx wires of the adapter together if you get an echo of what you send to the terminal, the loopback test is working If the connection to the device is working you will get this screen Since the Gotek firmware is protected against the read, the software ask you to remove the protections. This will erase the flash and the firmware shipped with the device will be lost. Please note that this operation cannot be reverted Press Remove ProtectionPress  OK Press Next. Press Next. Select the firmware HEX file and correct the settings according to this screenshot if needed. Then press Next The flash process begin Take 12 minutes. Once you got this last window, the device is ready You can disconnect all wires and connect the emulator into your Amiga. Dont forget to move the jumper to the  S0  position to replace DF0. BUT HOW THIS IS POSSIBLE TELL ME MORE WHAT IS INSIDE THESE DRIVES The Gotek drives use a powerful Cortex ARM based STM3. MCU working at 7. Mhz with lots of timers with DMA support, which make the job somewhat easy. For instance, this MCU only need 0. MFM encode an Amiga sector, with all the parity checksums computation. DMA and timers are used to stream out the MFM flux so almost no MCU time is used for this task. The MCU is free to do others job in the same time prepare the next sector. Thanks to this, all is done in realtime and no extra buffer is needed to precomputegenerate the track. The write process also use DMA and a timer block to capture the incoming flux. Once captured some functions find the sectors into the flux, decode  and check the sectors parity checking and write back the data to the ADF on the USB stick if the parity is good. As many ARM based MCU this one have a bootloader in ROM allowing the Flash programming through various interfaces, which make this project possible. Regarding the firmware, less than the half of the Flash space is actually used. Here is the schematic of the Gotek drive FULL RESOLUTION SCHEMATIC HERE. PCB TOP side. FULL RESOLUTION TOP PCB HERE.
