Damien George 22cedef95f stmhal/usbdev: For MSC implement SCSI SYNCHRONIZE_CACHE command.
Currently just a dummy command that returns "success", but it's needed for
some O/S's to correctly talk with the SCSI layer.

Sylvain Pelissier 6adcf7bb82 stmhal: Pass USB handler as parameter to allow more than one USB handler 2017-06-07 15:50:26 +10:00
Pavol Rusnak 0883a7e72f stmhal: Implement SNAK/CNAK mechanism for USB HID receive.
This implements flow control in case user does not call recv method often
enough (it tells host side to stop sending more data).

Philip Potter eb239b8398 stmhal/usb: Add support to receive USB HID messages from host. 2016-10-04 15:38:01 +11:00
Philip Potter 03de5a13cf stmhal/usbdev: Add OUT endpoint to HID interface. 2016-10-04 15:20:11 +11:00
Tony Abboud 8d8fdcb4be stmhal: add option to query for the current usb mode
Fetch the current usb mode and return a string representation when
pyb.usb_mode() is called with no args. The possible string values are interned
as qstr's. None will be returned if an incorrect mode is set.

Damien George b1f68685ec stmhal: In USB HID driver, make polling interval configurable.
When setting usb_mode to "HID", hid config object now has
polling-interval (in ms) as the 4th element.  It mmust now be a 5-tuple
of the form:

(subclass, protocol, max_packet_len, polling_interval, report_desc)

The mouse and keyboard defaults have polling interval at 8ms.

Damien George 55d6218b9a stmhal: Properly define pyb.usb_mode() semantics. 2015-02-13 14:02:51 +00:00
Damien George 65af7ebdc5 stmhal: Put CDC last in config descriptors to match with iface nums.
Apparently the order of interface numbers should be sequential and
increasing in a config descriptor.  So as to retain compatibility with
Windows drivers for the CDC+MSC and CDC+HID modes, we move the CDC
configs to the end of the descriptors, instead of changing the interface
numbers.

See PR #957 for background.

Damien George 39ce2db181 stmhal: Add "CDC" option to pyb.usb_mode, for CDC device only. 2015-02-13 14:02:51 +00:00
Damien George d39c7aa517 stmhal: Add Python-configurable USB HID mode.
Different HID modes can be configured in Python.  You can either use
predefined mouse or keyboard, or write your own report descriptor.

Damien George b384bcc5de stmhal: Remove unused usbdev files, and move used ones up a dir.
The unused files are from the ST demos for different USB classes and are
not needed for the stmhal port.

Damien George 21dfd207ca stmhal: Fill in USB class/subclass/proto for CDC+HID device.
Also change HID device from keyboard to mouse (should have been mouse
all along).

Damien George 1d7fb82f0a stmhal: Change 64-bit arithmetic to 32-bit for SD card block addressing.
By measuring SD card addresses in blocks and not bytes, one can get away
with using 32-bit numbers.

This patch also uses proper atomic lock/unlock around SD card
read/write, adds SD.info() function, and gives error code for failed
read/writes.

Damien George 6d983539bc stmhal: Improve flash storage cache management.
Internal flash used for the filesystem is now written (from the cache)
only after a 5s delay, or when a file is closed, or when the drive is
unmounted from the host.  This delay means that multiple writes can
accumulate in the cache, and leads to less writes to the flash, making
it last longer.

It's implemented by a high-priority interrupt that takes care of flash
erase and write, and flushing the cache.

This is still only an interim solution for the flash filesystem.  It
eventually needs to be replaced with something that uses less RAM for
the cache, something that can use more of the flash, and something that
does proper wear levelling.

Damien George 9699ea6a2f stmhal: Fix USB MSC so that it unmounts correctly on Mac OS X.
Mac OS X sends a SCSI command to remove the medium when it unmounts a
drive.  If this command is not honoured, then OS X will automatically
remount the drive, making it impossible to eject.  This patch disables
the USB MSC when the right SCSI command is sent.

Damien George 038df43183 stmhal: Implement selector for USB device mode; improve boot up.
Can now choose at boot up whether the USB device is CDC+MSC or CDC+HID.
Choice is made by an option in boot.py, with default being CDC+MSC.
HID+MSC is not currently supported, but should be easy to implement.

Boot up now has ability to change the reset mode: hold down USR switch
while booting and LEDs will count from 1 to 7 to indicate the boot mode.
Release USR when correct mode is selected.  Current modes are 1 (normal
boot), 2 (safe mode), 3 (reset FS mode).

Damien George 64563e39b3 stmhal: Add CDC+HID USB device.
The HID device must appear before the CDC in order for both to work at
the same time.

Whilst the code is working, it's not currently used.

Damien George 8913c04831 stmhal: Add support for USB MSC device.
This gives a functioning, independent MSC device.

Damien George b30c02afa0 stmhal: Get USB enumerating a CDC device.
Enumerates CDC device over USB, but doesn't transmit/receive yet.
