This adds a script to generate the peripherals files (except clock).
It adds support for the 1015, 1020, 1040, and 1050 EVKs.
Some work was started on 1176 but it isn't working. So, the board
def is in a separate branch.
Fixes#3521. Fixes#2477.
tested on metro m7 (green prototype version) with max98357a i2s amplifier and the following test code:
```py
import board
import time
import digitalio
from audiobusio import I2SOut
from audiocore import RawSample
from microcontroller import pin
from ulab import numpy as np
n = np.array(np.sin(np.linspace(0, np.pi*2, 218, endpoint=False)) * 200, dtype=np.int16)
print(n)
r = RawSample(n, sample_rate=8000, channel_count=2)
def main():
with digitalio.DigitalInOut(board.LED) as l:
l.switch_to_output(True)
value = False
while True:
with I2SOut(pin.GPIO_06, pin.GPIO_07, pin.GPIO_04) as i:
time.sleep(.01)
l.value = value = not value
i.play(r, loop=True)
print(i.playing)
time.sleep(.5)
i.stop()
print("STOPPED")
print(i.playing)
time.sleep(.5)
i.play(r, loop=True)
print(i.playing)
print("PLAY AGAIN")
time.sleep(.5)
time.sleep(1)
```
Only stereo, 16-bit, raw samples were tested; the sample rate is actually fixed
at 48kHz in the core right now. There is more to do, but the basics work.

* Enable dcache for OCRAM where the VM heap lives.
* Add CIRCUITPY_SWO_TRACE for pushing program counters out over the
SWO pin via the ITM module in the CPU. Exempt some functions from
instrumentation to reduce traffic and allow inlining.
* Place more functions in ITCM to handle errors using code in RAM-only
and speed up CP.
* Use SET and CLEAR registers for digitalio. The SDK does read, mask
and write.
* Switch to 2MiB reserved for CircuitPython code. Up from 1MiB.
* Run USB interrupts during flash erase and write.
* Allow storage writes from CP if the USB drive is disabled.
* Get perf bench tests running on CircuitPython and increase timeouts
so it works when instrumentation is active.
Changed a few things in the link step that satisfies the teensy
loader apps, both the teensy.exe as well as the teensy_loader_cli
such that when you program the board again it should retain the
file sytem that is stored in the upper area of the Flash
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.
