Hello All I am trying to software implement a I2C Master in my 16C62. I have included some code from AN554 (i2c_high.inc and i2c.h) in my main program. This should make me able to call various macro«s and subroutine«s which handle all the I2C stuff. I have followed the test examples from Microchip, but my program does not work out the way I want it to. Does any of you have a program where you use the AN554 code or some other I2C mester software ? I you have, I would like to take a look at it. I am stucked so I am desperate for some new inspiration With kind regards GDK-SSJ - Steen Schelle Jensen Dept.: 1545 Internet e-mail: ssjensen@grundfos.com
