curious to know why manual delays used, and not the SPI hardware peripheral?
Why don't you run down to your Ford dealer, and ask them?
The library was contributed by Adafruit. Ask THEM why.
sure, but i thought somebody with better knowledge of the arduino SPI workings would be able to simply spot if or why the hardware was incompatible.
It’s a read only device, right? So not using the hw spi frees up a pin…
See why you should put comments in your code?
