I have a chip that does not work with SPI so I have to “bit bang” it.
The OutputPort is so slow I can see the lights update like a chaser pattern instead of the instant update I am looking for. I had the same speed issues in the netduino. In arduino I had to use direct memory access to get the speed needed. I am thinking I may need to do the same here but wanted to see if there are any other alternatives for faster pin updates.
Seem from reading I would setup using OutputPort to the pin for proper setup … but then I could use the Register class to set the pin value quicker than using Write. If this is the only alternative and is correct … I need help with the address for pins d8 and d9.
I realize I am a newbie attempting to use advanced features right off the bat … but I have a very focused goal. Once I see the system can handle running the number of chips needed, then I’ll work on all the fun stuff around it.
