Move atmel-samd to tinyusb and support nRF flash.
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.

Move pin struct to the peripherals library.
Its slimmed down by removing the qstr and bit packing TCC info.

The trinket m0 build actually grows by 20 bytes. The arduino zero
build shrinks by 188 bytes.

Scott Shawcroft a5e03b76a6 Split out the peripherals library in preparation of sharing with MakeCode. 2018-06-15 16:16:21 -07:00
Scott Shawcroft 2fbab8067a Prevent freezing USB during high frequency PulseIn.
We now track the last time the background task ran and bail on the
PulseIn if it starves the background work. In practice, this
happens after the numbers from pulsein are no longer accurate.

This also adjusts interrupt priorities so most are the lowest level
except for the tick and USB interrupts.

Fixes #516 and #876

Scott Shawcroft 9920f0a5de atmel-samd: Make ticks more atomic.
Always use current_tick when sub millisecond precision is required.
Otherwise getting the ms/us to correspond is tricky.

Scott Shawcroft fd71e56891 atmel-samd: Re-org helper peripheral files into their own subdirectory.
Ideally in the future they won't depend on ASF4 or MicroPython.

Roy Hooper 3fd9900ea7 disable pins on trinket_m0 so that we can free a fair bit of flash - Issue #840 2018-05-15 13:13:59 -04:00

Scott Shawcroft 812fe0c93f Turn on nvm in 3.0.
Its 256b on M0 and 8k on M4 to match flash erase sizes.

Fixes #758

Jeff Epler fe6f5aaa70 atmel-samd: reset: reset() was always entering bootloader mode
.. set the dbl_tap word to a different special value unless
RUNMODE_BOOTLOADER was selected

Jeff Epler c0029e1d97 Don't lose half of the processor's serial number
Before this change, `microcontroller.cpu.uid` returned values
where the top 4 bits of each byte were zero, because of
an incorrect bitmask used in this function.

Scott Shawcroft 88aa0e2660 Remove SERCOM pointers from pin data structure because index is
enough.

This saves 380 bytes on the Arduino Zero build. (More pins ==
more savings.)
