be used for setup and basic communications. This is a list of the DOS utilities supplied:
C Library/Programs
Procedure or
File Name
Subroutine Name
Brief Functional Description
i2c.h
setup
Sets user defined initial conditions.
getstatus
Reads status register.
sendaddress

sendstop
Sends stop signal.
writebyte
Writes a byte of data to a previously specified address.
readbyte
Reads a byte of data from a previously specified address.
