设置SPI多个片选引脚除了config里面定义的其余引脚是否需要用GPIO虚拟，同时虚拟出来的引脚对传输速率是否有影响 可以使用GPIO模拟，在每次SPI发送之前，对SPI的片选信号也会进行控制，所以SPI的片选信号就是在每次需要发送到某个设备的时候，将CS片选端进行 ...

This is due to the internal 100k pull-up resistors that cannot be disabled within the IO expander. This is why there is a difference between HIGH and LOW inputs. LOW inputs will cause current to flow ...
