Documentation states that get_last_received_report() function should
return None if there was no report received previously, otherwise it
should return report. Moreover, same report should be returned only
once. That makes it possible to reliably process incoming OUT/Feature
reports.
This patch adds an array that stores flags if report with particular
ID was received and updates get_last_received_report() to match its
documentation.
* Reduce the number of supported HID reports of IDs per descriptor.
This saves ~200 bytes in the default HID objects.
* (Not enabled) Compute QSTR attrs on init. This trades 1k RAM for
flash. Flash is the default (1).
The default KEYBOARD report descriptor had a signed/unsigned error,
and also could have allowed more keycodes. So I changed it, using the
very vanilla descriptor from a very plain extremely common commercial
keyboard, modifying it only have 5 LED's instead of 3, and added a
report ID.
This code is shared by most parts, except where not all the #ifdefs
inside the tick function were present in all ports. This mostly would
have broken gamepad tick support on non-samd ports.
The "ms32" and "ms64" variants of the tick functions are introduced
because there is no 64-bit atomic read. Disabling interrupts avoids
a low probability bug where milliseconds could be off by ~49.5 days
once every ~49.5 days (2^32 ms).
Avoiding disabling interrupts when only the low 32 bits are needed is a minor
optimization.
Testing performed: on metro m4 express, USB still works and
time.monotonic_ns() still counts up
Otherwise, examples like the one attached to the related issue fail
because tud_hid_ready never returns true.
Testing performed: Adapted the example to nrf particle xenon (it was
handy), removed dependency on IR, verified that the problem occurred
before this change, and that it was fixed after this change.
Closes: #2048
The previous code assumed HID report ids were consecutive. This is
not true in the CircuitPython descriptor where report ids are fixed
for each report type.
Fixes#1617
This started while adding USB MIDI support (and descriptor support is
in this change.) When seeing that I'd have to implement the MIDI class
logic twice, once for atmel-samd and once for nrf, I decided to refactor
the USB stack so its shared across ports. This has led to a number of
changes that remove items from the ports folder and move them into
supervisor.
Furthermore, we had external SPI flash support for nrf pending so I
factored out the connection between the usb stack and the flash API as
well. This PR also includes the QSPI support for nRF.
