robert-hh c3afafd1ec samd/boards: Clean up comments and some pins in pins.csv files.
Remove two SPARKFUN_SAMD51_THINGS_PLUS pin definitions.  There were
definitions of TXD and RXD, but these pins do not exist on the board.  They
were only shown in the schematics.

Also remove any reference to LED_.  This is just a text change, no
functional change.

robert-hh 4598b89ce9 samd: Add Pin.board and Pin.cpu classes to Pin.
For compatibility with other ports.  Code increase up to ~1250 bytes for
SAMD21.  The feature is configurable via MICROPY_PY_MACHINE_PIN_BOARD_CPU
in case flash memory is tight.

robert-hh e69313f89c samd: Add a vref=num option to the ADC and DAC constructor.
ADC: The argument of vref=num is an integer. Values for num are:

    SAMD21:
    0  INT1V   1.0V voltage reference
    1  INTVCC0 1/1.48 Analog voltage supply
    2  INTVCC1 1/2 Analog voltage supply (only for VDDANA > 2.0V)
    3  VREFA   External reference
    4  VREFB   External reference

    SAMD51:
    0  INTREF  internal bandgap reference
    1  INTVCC1 Analog voltage supply
    2  INTVCC0 1/2 Analog voltage supply (only for VDDANA > 2.0v)
    3  AREFA   External reference A
    4  AREFB   External reference B
    5  AREFC   External reference C (ADC1 only)

DAC: The argument of vref=num is an integer. Suitable values:

    SAMD21:
    0  INT1V   Internal voltage reference
    1  VDDANA  Analog voltage supply
    2  VREFA   External reference

    SAMD51:
    0  INTREF Internal bandgap reference
    1  VDDANA Analog voltage supply
    2  VREFAU Unbuffered external voltage reference (not buffered in DAC)
    4  VREFAB Buffered external voltage reference (buffered in DAC).

robert-hh 9d0aefe719 samd/boards/SEEED_WIO_TERMINAL: Enable using the 32kHz crystal.
That was missing from the configuration.
2022-11-08 23:26:24 +11:00
robert-hh ac1e31267b samd/boards: Rework the pins.csv files.
Changes are:
- Remove the LED_Pxxx definitions from pins.csv, now that the LED class is
  gone.
- Remove the '-' lines.
- Add default lines for USB and SWCLK, SWDIO.
2022-10-25 23:40:28 +11:00
robert-hh a6760bd4ef samd/modmachine: Replace the LED class by the Signal class.
It simplifies and improves the code.  The LED_Pxxx lines of the board.csv
lines can still be used, but will be taken as Pin definitions.
2022-10-25 23:39:41 +11:00
robert-hh e5cf3fab95 samd/machine_pin: Change the pin handling and naming/numbering.
Pin numbers are now the MCU port numbers in the range:

    PA0..PA31:  0..31
    PB0..PB31: 32..63
    PC0..PC31: 64..95
    PD0..PD31: 96..127

Pins can be denoted by the GPIO port number, the name as defined in
pins.csv or a string in the form Pxnn, like "PA16" or "PD03".

The pins.c and pins.h files are now obsolete.  The pin objects are part of
the AF table.

As result of a simplification, the code now supports using pin names or
numbers instead of pin objects for modules like UART, SPI, PWM, I2C, ADC,
pininfo.

robert-hh e7aa9700ca samd/boards/SEEED_WIO_TERMINAL: Declare more pins for SEEED WIO board.
Defining all pins from the external 40 Pin connector, and some internal
pins like the one for SD and LCD.
2022-10-25 23:28:34 +11:00
robert-hh f0399d35e4 samd/modmachine: Get the bootloader magic address from the lib.
Instead of being hard-coded, and then it works for all MCUs.

That fits except for a Sparkfun SAMD51 Thing Plus (known) bug, which uses
192k - 4 as magic address.  Therefore, that address is set as well to avoid
a problem when this bug is fixed by Sparkfun.
2022-10-25 23:09:04 +11:00
robert-hh 0d3f0d7470 samd/boards/SPARKFUN_SAMD51_THING_PLUS: Add board files for Thing Plus.
That device uses an SAMD51J20 MCU with 256k RAM and 1024k flash.
2022-10-25 22:42:17 +11:00
robert-hh 366c801b35 samd/machine_pin: Change the printing of Pin and LED objects.
It now prints lines like:

    Pin("D9", mode=IN, pull=PULL_UP, GPIO=PA07)

or

    LED("LED")

showing for consistency the names as given in pins.csv.  For pins, the GPIO
numer is printed as well for a reference.

robert-hh 65f99e371d samd/boards: Use the same linker file for all SAMD51x19 variants. 2022-10-06 23:14:21 +11:00
robert-hh 9f4df86016 samd/boards: Move the flash filesystem definitions to the linker files.
They used to be in mpconfigmcu.h, but have to be different for different
chip variants, like the SAMD51x20.
2022-10-06 23:14:08 +11:00
robert-hh 85fb8b8b02 samd/pin_af: Simplify the pin-af-table handling.
Changes are:
- The pin-af-table-SAMDxx.csv file are moved to the mcu directories with
  the name as pin-af-table.csv.
- The handling in Makefile and pin_af.c is simplified.
2022-10-06 23:05:46 +11:00
robert-hh 20e7313453 samd/clock_config: Add HW_DFLL_USB_SYNC and HW_MCU_OSC32KULP extensions.
Two new compile flags are:

MICROPY_HW_DFLL_USB_SYNC: Effective only if DFLL48 does not run from the
crystal.  It will synchronize the DFLL48M clock with the USB's SOF pulse.
If no USB is connected, it will fall back to open loop mode.  The DFLL48M
clock is then pretty precise, but with a higher clock jitter at SAMD51
devices.

MICROPY_HW_MCU_OSC32KULP: Effective only if the devics uses a crystal as
clock source.  Run the MCU clock from the ULP 32kHz oszillator instead of
the crystal.  This flag was added to cater for a interference problem of
the crystal and Neopixel/Debug pins at Adafruit FEATHER Mx boards, which
causes the board to crash.  Drawback: ticks_ms() and time.time() vs. than
ticks_us() and the peripherals like PWM run at not synchronous clocks.
2022-10-06 23:03:08 +11:00
robert-hh a9304af8fa samd/boards: Add missing/lost board config and pin definitions.
Fixes are:
- Pin definitions for ADAFRUIT_FEATHER_Mx_EXPRESS and
  ADAFRUIT_ITSYBITSY_M4_EXPRESS.
- For ADAFRUIT_ITSYBITSY_M0_EXPRESS, change the MISO/MOSI name.
- For MINISAM_M4, add the default SPI pins.
- For boards with 32k crystal, add the XOSC32K setting.

robert-hh aa6dbbcffd samd/mcu: Factor out MCU policy for SAMD21 and SAMD51.
Which contains a mpconfigmcu.h, mpconfigmcu.mk and manifest.py file for
each MCU group.  That looks better than the previous choice.
2022-10-06 22:56:13 +11:00
robert-hh 32c973d554 samd/machine_timer: Add machine.Timer based on the shared soft-timer. 2022-10-06 22:52:39 +11:00
robert-hh 45bf25a002 samd/moduos: Add uos.urandom() for SAMD51.
Based on the hardware RNG.

robert-hh 6c037af086 samd/boards: Create pin_af_table.c from pin_af_table_SAMDxx.csv files.
This step just creates the table.  The firmware cannot be built at this
commit.  The next commit will complete the pin-af mechanism.
2022-10-06 22:38:45 +11:00
robert-hh e8615f5813 samd/machine_pin: Allow specifying a pin or LED by its name as a string.
The names are defined in pins.csv.
2022-10-06 22:37:46 +11:00
robert-hh 949a808076 samd/boards: Add ADAFRUIT_FEATHER_M4_EXPRESS and _ITSYBITSY_M0_EXPRESS.
These two boards are used for testing, so it is favorable to have them
added early.

The full test set is:
- ADAFRUIT_FEATHER_M4_EXPRESS: SAMD51 with 32kHz crystal.
- ADAFRUIT_ITSYBITSY_M0_EXPRESS: SAMD21 without crystal.
- ADAFRUIT_ITSYBITSY_M4_EXPRESS: SAMD51 without crystal.
- SEEED_XIAO: SAM21 with 32kHz crystal.
2022-10-06 22:32:01 +11:00
robert-hh a5d5ecbf84 samd/boards: Move mcu-specific settings into a mpconfig_samdXX.h file.
Located at the boards directory. That way, the mpconfigboard.h files are
almost empty, just setting the board name and the MCU name.
2022-10-06 22:30:37 +11:00
robert-hh 0420799a84 samd/boards: Replace pins.c and pins.h by pins.csv.
The files pins.c and pins.h are generated during the build process from
pins.csv, using a make-pins.py script.
2022-10-06 22:29:49 +11:00
robert-hh 85afed569d samd: Remove the existing provisional support for REPL on UART.
It was only partially working and will be rpelaced later by a full
machine.UART class implementation.
2022-10-06 22:29:06 +11:00
Damien George 5c32111fa0 ports: Reformat more C and Python source code.
These files that are reformatted only now fall under the list of files to
apply uncrustify/black formatting to.
