.. _samd_pinout:

Pinout for the SAMD machine modules
===================================

The assignment of device functions to pins is very flexible. The same function may be used
at different pins. The representation of the assignment choices are given by a table,
which is a subset of the MCU's Pin MUX table and is specific to each board, as the
available pin set varies. The structure of the table is the same for each board, but
the set of rows is different.

Description of the columns:

- *Pin* - The number that is expected at ``machine.Pin(n)``, if the pin is given
  as a number.
- *GPIO* - The GPIO name, which can be used as argument to ``machine.Pin("name")``.
- *Pin Name* - The boards name, which can be used as argument to ``machine.Pin("name")``.
- *IRQ* - The IRQ number assigned to that GPIO, used internally by ``Pin.irq()``. When
  using ``Pin.irq()``, different pins must use different IRQs
- *ADC* - The ADC channel assigned to the pin. When using ADC, different pins must
  not use the same ADC channel.
- *Serial* - Two columns with optional Serial signal assignments. Both may be used.
  The cell content is device #/pad #. The pad # is the respective internal
  signal of that serial device. Details below.
- *TCC/TC* - Two columns with assignments of the TCC modules for PWM.
  The cell content is device #/output #. For PWM, devices 0, 1, and 2
  are used. The TC device pair 3/4 is used for ``ticks_us()``.

SAMD21 UART assignments
```````````````````````
The UART devices and signals must be chosen according to the following rules:

- The TX signal must be at a Pin with pad numbers 2 or 0, like Pin D1 with serial
  device 0 or 2.
- The RX pin may be assigned to one of the other pads.

Examples for Adafruit ItsyBitsy M0 Express:

- uart 0 at pins D0/D1  This is the default UART at the RX/TX labelled pins
- uart 1 at pins D12/D10
- uart 2 at pins D0/D1
- uart 3 at pins D11/D13
- uart 4 at pins D2/D5
- uart 5 at pins SCL/SDA

or other combinations. For hardware flow control, tx must be at pad 0, rx at pad 1,
rts at pad 2 and cts at pad 3. This applies for instance to
UART 3 or UART 1 at the pins D13/D11/D10/D12 for rx/tx/rts/cts.

SAMD21 I2C assignments
``````````````````````
The I2C devices and signals must be chosen according to the following rules:

- The SDA signal must be at a Pin with pad numbers 0.
- The SCL signal must be at a Pin with pad numbers 1.

Examples for Adafruit ItsyBitsy M0 Express:

- I2C 0 at Pin A3/A4
- I2C 1 at pins D11/D13
- I2C 2 at the pins D4/D3
- I2C 3 at the pins SDA/SCL This is the default I2C device at the SDA/SCl labelled pin
- I2C 4 at the pins A1/A2
- I2C 5 at the pins SDA/SCL,

or other combinations.

SAMD21 SPI assignments
``````````````````````
The SPI devices and signals must be chosen according to the following rules:

- The following pad number pairs are suitable for MOSI/SCK: 0/1, 2/3, 3/1, and 0/3.
- The MISO signal must be at a Pin with a different pad number than MOSI or SCK.

Examples for Adafruit ItsyBitsy M0 Express:

- SPI 0 at pins D0/D4/D1
- SPI 1 at pins D11/D12/D13
- SPI 2 at pins D0/D4/D1
- SPI 3 at pins D11/D12/D13
- SPI 4 at Pin MOSI/MISO/SCK This is the default SPI device at the MOSI/MISO/SCK labelled pins.

or other combinations.


SAMD21 PWM assignments
``````````````````````

The TCC/TC device numbers 0, 1 and 2 can be used for PWM. Device 0 has four
channels, device 1 and 2 have two channels. So in total 3 different PWM
frequencies can be used, and 8 different duty cycle values.

The DAC output for the Adafruit ItsyBitsy M0 Express board is available at the pin A0.

Description of the columns:

- *Pin* - The number that is expected at ``machine.Pin(n)``, if the pin is given
  as a number.
- *GPIO* - The GPIO name, which can be used as argument to ``machine.Pin("name")``.
- *Pin Name* - The boards name, which can be used as argument to ``machine.Pin("name")``.
- *IRQ* - The IRQ number assigned to that GPIO, used internally by ``Pin.irq()``. When
  using ``Pin.irq()``, different pins must use different IRQs
- *ADC* - The ADC0/1 channel assigned to the pin. When using ADC, different pins must
  not use the same ADC device and channel.
- *Serial* - Two columns with optional Serial signal assignments. Both may be used.
  The cell content is device #/pad #. The pad # is the respective internal
  signal of that serial device. Details below.
- *TC* - These device are currently not assigned to Pin. the TC device pair 0/1
  is used for ``ticks_us()``.
- *PWM* - Two columns with assignments of the TCC modules for PWM
  The cell content is device #/output #. Details below.

SAMD51 UART assignments
```````````````````````
The UART devices and signals must be chosen according to the following rules:

- The TX signal must be at a Pin with pad numbers 0, like Pin D1 with serial
  device 3.
- The RX pin may be assigned to one of the other pads.

Examples for Adafruit ItsyBitsy 4 Express:

- uart 0 at pins A4/A1
- uart 1 at pins D1/D0   This is the default UART at the RX/TX labelled pins
- uart 2 at pins SCL/SDA  This is the default I2C device at the SDA/SCl labelled pin
- uart 3 at pins D0/D1
- uart 4 at pins SDA/SCL
- uart 5 at pins D12/D13

or other combinations. For hardware flow control, tx must be at pad 0, rx at pad 1,
rts at pad 2 and cts at pad 3. This applies for instance to
UART 5 at the pins D12/D13/D10/D11 for rx/tx/rts/cts.

SAMD51 I2C assignments
``````````````````````
The I2C devices and signals must be chosen according to the following rules:

- The SDA signal must be at a Pin with pad numbers 0.
- The SCL signal must be at a Pin with pad numbers 1.

Examples for Adafruit ItsyBitsy M0 Express:

- I2C 0 at pins A3/A4
- I2C 1 at pins D0/D1
- I2C 2 at the pins SDA/SCL
- I2C 3 at the pins D1/D0
- I2C 4 at the pins A2/A3
- I2C 5 at the pins D12/D13

or other combinations.

SAMD51 SPI assignments
``````````````````````
The SPI devices and signals must be chosen according to the following rules:

- The following pad number pairs are suitable for MOSI/SCK: 0/1 and 3/1.
- The MISO signal must be at a Pin with a different pad number than MOSI or SCK.

Examples for Adafruit ItsyBitsy M0 Express:

- SPI 1 at Pin MOSI/MISO/SCK  This is the default SPI device at the MOSI/MISO/SCK labelled pins.
- SPI 3 at pins D13/D11/D12
- SPI 5 at pins D12/D3/D13

or other combinations.


SAMD51 PWM assignments
``````````````````````

The TCC/PWM device numbers 0 through 4 can be used for PWM. Device 0 has six
channels, device 1 has four channels, device 2 has three channels and devices
3 and 4 have two channels. So in total up to 5 different PWM frequencies
can be used, and up to 17 different duty cycle values. Note that these numbers
do not apply to every board.

The DAC outputs for the Adafruit ItsyBitsy M4 Express board are available at the pins A0 and A1.

For the definition of the table columns see the explanation at the table for
Adafruit ItsyBitsy M4 Express :ref:`samd51_pinout_table`.

The default devices at the board are:

- UART 2 at pins PA13/PA12, labelled RXD/TXD
- I2C 5 at pins PA22/PA23, labelled SDA/SCL
- SPI 4 at pins PB12/PB11/PB13, labelled MOSI, MISO and SCK
- DAC output on pins PA02 and PA05, labelled A0 and A4

Scripts for creating the pin assignment tables
----------------------------------------------

The tables shown above were created with small a Python script running on the target board::

  from samd import pininfo
  from machine import Pin
  import os

  def print_item(e, txt):
      print(txt, end=": ")
      if e == 255:
          print(" - ", end="")
      else:
          print("%d/%d" % (e >> 4, e & 0x0f), end="")

  def print_pininfo(pin_id, name, info):

      print("%3d" % pin_id, end=" ")
      print("%4s %12s" % (info[0], name), end="")
      print(" IRQ:%2s" % (info[1] if info[1] != 255 else "-"), end="")
      print(" ADC0:%2s" % (info[2] if info[2] != 255 else "-"), end="")
      if len(info) == 7:
          print_item(info[3], " Serial1")
          print_item(info[4], " Serial2")
          print_item(info[5], " PWM1" if (info[5] >> 4) < 3 else "   TC")
          print_item(info[6], " PWM2")
      else:
          print(" ADC1:%2s" % (info[3] if info[3] != 255 else "-"), end="")
          print_item(info[4], " Serial1")
          print_item(info[5], " Serial2")
          print_item(info[6], " TC")
          print_item(info[7], " PWM1")
          print_item(info[8], " PWM2")
      print()

  def tblkey(i):
      name = i[1]
      if name != "":
          if len(name) < 3:
              return " " + name
          else:
              return name
      else:
          return "zzzzzzz%03d" % i[0]

  def table(num=127, sort=True):
      pintbl = []
      inv_bd = {v: k for k, v in Pin.board.__dict__.items()}
      for i in range(num):
          try:
              p = Pin(i)
              pi = pininfo(p)
              if p in inv_bd.keys():
                  name = inv_bd[p]
              else:
                  name = ""
              pintbl.append((i, name, pininfo(i)))
          except:
              pass
              # print("not defined")

      if sort:
          pintbl.sort(key=tblkey)
      for item in pintbl:
          print_pininfo(item[0], item[1], item[2])
