SAMD机器模块的引线¶
将设备功能分配给引脚非常灵活。相同的功能可用于不同的引脚。分配选择的表示由一个表给出，该表是MCU引脚MUX表的一个子集，并且由于可用引脚集的不同而特定于每个板。每个板的表格结构相同，但行集合不同。

列的说明：
Pin-如果Pin为数字，则
machine.Pin(n)处预期的数字。这不是GPIO编号，而是板特定定义文件中给出的板引脚编号。GPIO - GPIO-GPIO编号。
Pin Name-作为
machine.Pin("name")参数的Pin的名称。IRQ - 分配给该GPIO的IRQ编号，由
Pin.irq(). When 内部使用。使用Pin.irq()时，不同引脚必须使用不同的IRQADC - 分配给管脚的ADC通道。使用ADC时，不同引脚不得使用相同的ADC通道。
Serial-两列可选串行信号分配。两者都可以使用。单元格内容为设备#/pad#。焊盘#是该串行设备的相应内部信号。详情如下。
TCC/TC -两列为PWM的TCC模块分配。单元格内容为device#/output#。对于PWM，使用设备0、1和2。TC设备对3/4用于
ticks_us()。
SAMD21 UART分配¶
必须根据以下规则选择UART设备和信号：
TX信号必须位于焊盘编号为2或0的引脚，如串行设备为0或2的引脚D1。
RX引脚可以分配给其他焊盘之一。
Adafruit ItsyBitsy M0 Express示例：
引脚D0/D1处的uart 0这是RX/TX标记引脚处的默认uart
插脚D12/D10处的uart 1
插脚D0/D1处的uart 2
插脚D11/D13处的uart 3
插脚D2/D5处的uart 4
插脚SCL/SDA处的uart 5
或其他组合。
SAMD21 I2C分配¶
必须根据以下规则选择I2C设备和信号：
SDA信号必须位于焊盘编号为0的引脚处。
SCL信号必须位于焊盘编号为1的引脚处。
Adafruit ItsyBitsy M0 Express示例：
引脚A3/A4处的I2C 0
引脚D11/D13处的I2C 1
引脚D4/D3处的I2C 2
引脚SDA/SCL处的I2C 3这是SDA/SCL标记引脚处的默认I2C设备
插脚A1/A2处的I2C 4
引脚SDA/SCL处的I2C 5，
或其他组合。
SAMD21 SPI分配¶
必须根据以下规则选择I2C设备和信号：
以下焊盘编号对适用于MOSI/SCK：0/1、2/3、3/1和0/3。
MISO信号必须位于焊盘编号与MOSI或SCK不同的引脚处。
Adafruit ItsyBitsy M0 Express示例：
SPI 0和引脚 D0/D4/D1

SPI 2 和引脚 D0/D4/D1
SPI 3和引脚D11/D12/D13
引脚MOSI/MISO/SCK处的SPI 4这是MOSI/MSO/SCK标记引脚处的默认SPI设备。
或其他组合。
SAMD21 PWM分配¶
TCC/TC设备编号0、1和2可用于PWM。设备0有四个通道，设备1和2有两个通道。因此总共可以使用3个不同的PWM频率和8个不同的占空比值。

有关表列的定义，请参阅表中Adafruit ItsyBitsy M4 Express Adafruit ItsyBitsy M4 Express引脚分配表的说明。
板上的默认设备为：
引脚PB23/PB22处的UART 1，标记为RXD/TXD
引脚PA22/PA23处的I2C 5，标记为SDA/SCL
引脚PB12/PB11/PB13处的SPI 4，标记为MOSI、MISO和SCK
引脚PA02和PA05上的DAC输出，标记为A0和A4
用于创建管脚分配表的脚本¶
上面显示的表是用目标板上运行的Python小脚本创建的：
from samd import pininfo
from machine import Pin
import os
def print_entry(e, txt):
print(txt, end=": ")
if e == 255:
print(" - ", end="")
else:
print("%d/%d" % (e >> 4, e & 0x0f), end="")
def print_pininfo(pin, info):
print("%3d" % pin, end=" ")
print("P%c%02d" % ("ABCD"[pin // 32], pin % 32), end="")
print(" %12s" % info[0], 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_entry(info[3], " Serial1")
print_entry(info[4], " Serial2")
print_entry(info[5], " PWM1" if (info[5] >> 4) < 3 else " TC")
print_entry(info[6], " PWM2")

print(" ADC1:%2s" % (info[3] if info[3] != 255 else "-"), end="")
print_entry(info[4], " Serial1")
print_entry(info[5], " Serial2")
print_entry(info[6], " TC")
print_entry(info[7], " PWM1")
print_entry(info[8], " PWM2")
