OK, I'm a total NEWB. basically i know enough to be dangerous, yet not quite enough to be productive, yet.


basically I'm starting small, one ADC channel output to a debug window. but im having some issues with the I2C protocol for this chip.

i have dragged together some data on how to communicate with the device, but all i am getting as a return value is %000000000000, further if a add pull up resistors per I2C spec i get %000011111111

my circuit is setup identical to the MAX127 data sheet

attached is my SPIN and MAX127 data sheet

please tell me how I'm doing this incorrectly. many thanks in advance!!!
