Renamed the board both name of directory within boards, but also the
name reported board name: board_id -- sparkfun_teensy_micromod
Adafruit CircuitPython 7.3.0-beta.0-10-g2a3eb49da-dirty on 2022-04-10; SparkFun Teensy MicroMod Processor with IMXRT1062DVL6A
While testing out this and the new MicroMod Teensy port, @mjs513
and myself found it desirable to have logical pin names for the
different Serial UART objects. It is a lot easier and clearer
to use and maintain to do something
like: uart4 = busio.UART(board.TX4, board.RX4)
than have to go look up the pin numbers for each board.
I fixed a couple issues in the pin name definitions.
The pin names are sort of Teensy centric in that the priority is given
to the pin names you would use in Arduino like D0, D1, ...
But also added names for the MicroMod names in particular the names
on the front of the ATP carrier board
Also updated manufacturer to be both PJRC and Sparkfun
This allows you to list and explore connected USB devices. It
only stubs out the methods to communicate to endpoints. That will
come in a follow up once TinyUSB has it. (It's in progress.)
Related to #5986
There are DNP resistors on the MIMXRT1010-EVK board (see SCH-45852)
that lead to these pins on the arduino-style header not being connected
through. In theory someone could populate them, but as it the presence
of these names in the pins module caused problems when they didn't work
as expected.
Closes#3012
This changes lots of files to unify `board.h` across ports. It adds
`board_deinit` when CIRCUITPY_ALARM is set. `main.c` uses it to
deinit the board before deep sleeping (even when pretending.)
Deep sleep is now a two step process for the port. First, the
port should prepare to deep sleep based on the given alarms. It
should set alarms for both deep and pretend sleep. In particular,
the pretend versions should be set immediately so that we don't
miss an alarm as we shutdown. These alarms should also wake from
`port_idle_until_interrupt` which is used when pretending to deep
sleep.
Second, when real deep sleeping, `alarm_enter_deep_sleep` is called.
The port should set any alarms it didn't during prepare based on
data it saved internally during prepare.
ESP32-S2 sleep is a bit reorganized to locate more logic with
TimeAlarm. This will help it scale to more alarm types.
Fixes#3786
This unifies the flash config to the settings used by the Boot ROM.
This makes the config unique per board which allows for changing
quad enable and status bit differences per flash device. It also
allows for timing differences due to the board layout.
This change also tweaks linker layout to leave more ram space for
the CircuitPython heap.
