- General STM32 HxC Floppy Emulator Firmware Usage                            -
-------------------------------------------------------------------------------

 -> Format the USB Stick in FAT32 (FAT12 & FAT16 also supported).

 -> (Optional if you have an LCD/OLED screen)
    Copy the right HXCSDFE.CFG file to the root of the USB Stick
    (See "Mode selection" below for more details).

 -> Copy or generate your disks images to the USB Stick.
    (See "File images supported" below for mode details).

 -> Insert the USB Stick into the emulator.

-------------------------------------------------------------------------------
- Mode selection                                                              -
-------------------------------------------------------------------------------

There are actually three main modes available :

---------------
- Normal mode -
---------------

In this mode the file image/disk to load is directly selected with the buttons
and the LCD screen. One I2C screen is needed to be able to use this mode.
An optional "select" push button can be connected on the JA connector.
No extra software needed.

config file is optional (Config-Less support).

If you you want to have the last image selection image feature, the config file
to copy to the root of the flash media is into the folder
Config_Files/Normal_mode/HXCSDFE.CFG

----------------
- Indexed mode -
----------------

In this mode the file images must be named DSKA0000.HFE/.IMG, DSKA0001.HFE/.IMG, DSKA0002.HFE/.IMG,...
(HFE & IMG images supported)
The 2/3 digits display shows the actual file number selected.

No LCD and/or extra push button is needed to use this mode.
No extra software needed.

This is the recommended mode when you don't have the extra LCD & button and when
your machine can't use the autoboot mode (see below).

The config file to copy to the root of the flash media for this mode :

Config_Files/Indexed_mode/HXCSDFE.CFG

-----------------------------------
- "Autoboot" / File selector mode -
-----------------------------------

In this mode, the AUTOBOOT.HFE software is used to select the images to load
directly on the computer.
This software is actually available on Amiga, Atari ST and CPC computers.

No LCD and/or extra push button is required to use this mode, but the LCD may help you
to see which disk is actually mounted.

The config and the software file to copy to the root of the flash media for this mode
are in the folder File_Selector/ and Config_Files/Autoboot_mode

-------------------------------------------------------------------------------
- Internal parameters settings                                                -
-------------------------------------------------------------------------------

There is many parameters that can be changed. You generally don't have to change
them as the default values are fine in most cases.
Anyway if needed these settings can be changed with the internal menu.
To access it, remove the USB stick and press both buttons. Then you can navigate
through the various available options.

If you don't have a LCD/OLED screen the alternate way to change them is to
use/edit the HXCSDFE.CFG file with the HxC Floppy Emulator software.

The file selectors have also a setting page that can be used to change these
parameters.

Here is some of the available parameters :

- Floppy Interface mode (predefined modes and custom modes).

- Single or Double step track mode.

- Emulation Bitrate (Auto or forced).

- Floppy write protect state.

- Step Sound output settings.

- LCD/OLED characters per line setting (16/18/20 or 21 characters per line).

- LCD Backlight timeout setting.

- Select Button emulation (on/off and timeout setting).

-------------------------------------------------------------------------------
- File images supported                                                       -
-------------------------------------------------------------------------------

-------------------------------------------------------------------------------
- Optional Add-on hardware                                                    -

--------------------------------------
- I2C SSD1306 128x32 OLED LCD Screen -
--------------------------------------
Note : Since the 3.0.26.1a

  You can connect an SSD1306 based 128x32 OLED screen.

  These screens are compatible with this firmware : http://www.ebay.com/itm/302110929185  ( IIC Interface ! )

  You can connect the screen directly to the J7 connector. (additional pull-up resistors NOT required.)

 - GND, VCC 3.3V, SCL and SDA position on J7 :

! > Take care with the 3.3V and GND while connecting the screen. Any mistake may damage the screen ! < !


-----------------------
- I2C 2x16 LCD Screen -
-----------------------

 These kind of I2C LCD boards are 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)

 (board + LCD)

 (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 additionnals 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:
 http://hxc2001.com/download/floppy_drive_emulator/Ext_Slim_HxC_Floppy_Emulator_I2C_LCD_Schematic.pdf

-----------------------
- Extra select button -
-----------------------

The optional select/middle button, usable with the "normal" mode
can be added on the JA jumper position.
JA is present near the floppy connector.

-----------------------
- Buzzer sound output -
-----------------------

You can connect a piezo or a magnetic buzzer to the JB jumper position.
A transistor is needed for the magnetic version.
The sound output can be disabled or enabled into the selector settings.
(Note : Please remove these old sound mod using directly the floppy step signal, they are producing reliability problems...)
