XIAO SAMD21 で CircuitPython で LED の点灯/消灯をやってみました | |
参考 | |
https://wiki.seeedstudio.com/Seeeduino-XIAO-CircuitPython | |
http://zattouka.net/GarageHouse/micon/Arduino/XIAO/gaiyo.htm | |
CircuitPython のコンソールで以下実施 | |
>>> import board | |
>>> from digitalio import DigitalInOut, Direction | |
>>> led = DigitalInOut(board.LED_INVERTED) | |
>>> led.direction = Direction.OUTPUT | |
XIAO オンボードのオレンジの LED が点灯しました。 | |
LED を消灯 | |
>>> led.value = True | |
LED を点灯 | |
>>> led.value = False | |
>>> help(board) | |
object <module 'board'> is of type module | |

XIAO にはオンボードで二つの青色 LED もあり、 | |
board.BLUE_LED1_INVERTED, board.BLUE_LED2_INVERTED が対応しているみたいです。 | |
UART-RX通信の受信時、送信時に点灯するようですが、 | |
board.LED_INVERTED 同様に Python で点灯/消灯させることができるっぽいです。 | |
