Hello again, I have a RN-Motor ST. Changing all the “i2c_byte = 255” into “i2c_byte = 0” has no effect. I have not tried pull up resistors until now. I think, if writing is possible there is no reason why reading makes problems. I have searched the net and found a thread on this problem, but it is in german only: http://www.roboternetz.de/phpBB2/viewtopic.php?t=10104 There you can find another solution, but it is written in Basic++ and I have no experience with it... If you can't find it please inform me and I will send you the programm. Greetings Gaston > > Hello, > I’m at a complete loss why the steps can’t be read out. > I have had no problems with any I2C device and my subroutines and it almost seems to me to be a hardware/ software problem of the RN-MOTOR ST but you could first try using different pull up resistors on the scl and sda line to see if this helps. > You could also try changing all the “i2c_byte = 255” into “i2c_byte = 0”. > Could it be that you have a RN-MOTOR GT instead of the ST version?? > Try asking on a forum if anybody has had problems reading out the steps of the motor controller. > Let me know how it works out. > Greetings, > H.J.
