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. This is NOT the GPIO number, but the board pin number, as
|
|
given in the board specific definition file.
|
|
- *GPIO* - The GPIO number.
|
|
- *Pin Name* - The name of a Pin which is expected 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

|
|
|
or other combinations.
|
|
|
|
SAMD21 I2C assignments

|
``````````````````````
|
|

|
|
|
|
The TCC/TC device numbers 0, 1 and 2 can be used for PWM. Device 0 has four

|
|

Scripts for creating the pin assignment tables
