Hi,
I am trying to use the DRV8830 with the arduino zero using the sparkfun minimoto lbr but I keep getting the error:
'TWBR' was not declared in this scope
TWBR = 72;
'TWCR' was not declared in this scope
TWCR = START_COND; // Send a start condition
^
as well as some other similar error messages. From what I can understand it seems like its because the lbr is designed for the uno. How can I adjust it to work with the zero?
Thanks,
Aaron

You have not posted your program
You have not told us what "lbr" you are using
You have not posted the full error message.
How can we help?
