Hi all,
I'm a bit confused - hope someone can help. I want to use SPI for output only. Do I need to connect the 'hspi sdi' pin (which is C.4 on a PICAXE-40X2)? I read that: "Due to the internal operation of the microcontrollers SPI port, a hspiout command will only function when the hspiin ‘input pin’ is in the expected default state".
But - I don't know what the 'expected default state' is. Can I leave hspi sdi unconnected, or should I tie it to ground, or what?
Thanks!
Pops
