Thank you for your response, neilgl!
After running your code I received what looks like a table with a 27 in the 7 column/02 row.
My MCP23017 does not have any of the address jumpers jumped, is that why I'm seeing a 27?
My output pin is connected to PB7, the last pin in the 1st row of pins, I assume that's why the 27 is in column 7?
So, is this confirming my hardware exists and my bus is enabled?
I'd LOVE to make this work without the adafruit stuff. My game is all buttons and LEDs, my needs are very simple.
Can you please suggest code that will turn on my LED?
(NOTE: I have a large pile of code written utilizing most all my native GPIO. I just don't know how to setup and read/toggle the MCP23017 GPIO)
THANK YOU THANK YOU THANK YOU!!
