 一方で、ArduinoのSPIライブラリは、[https://github.com/espressif/arduino-esp32/blob/3cbc405edf2448cf1d77b0a30a5e62ddab806a85/libraries/SPI/src/SPI.cpp#L277 ライブラリ中]に定義されるように、VSPI回路を利用します。更に、独自にSPIクラスをインスタンス化すると、[https://github.com/espressif/arduino-esp32/blob/3cbc405edf2448cf1d77b0a30a5e62ddab806a85/libraries/SPI/src/SPI.h#L53 こちら]にあるようにHSPIが利用されます。
+各SPIモジュールのピンアサインは以下の通りです。
