Hello nighteagle,
I have looked through the *I2C Bus Standard Routinen* and I must say that I am not very impressed.
The *I2C Bus Standard Routinen* does not support I2C clock stretching and I2C Nack.
This “could” be the reason why you are having problems controlling your servos.
Try the download “SD20 VIA EMULATED I2C BUS b1.0 for CCIMainU1.1 with CCISB.bas” here - > https://www.roboternetz.de/phpBB2/ze...highlight=sd20 and see if this works.
