Pololu serial 8 servo controlled using Labview

Hi,
Thanks for the help, is there a proper way to cycle through the baud rate? I remember you mentioning something earlier about power cycling the servo controller? Does that mean I just have turn off the controller each time I want to change the baud rate?

thanks

To change the baud rate, you must reset the controller. There are three ways to reset it:

  1. power cycle
  2. bring RST low for a brief time
  3. use the DTR/RTS reset feature described in the user’s guide

Thanks, will try that, do you have a suggested baud rate to try or should I just guess different ones?

thanks

I’m not sure I understand your question. The servo controller can handle baud rates from 1200-38400. I am not sure what will be the best baud rate for your system. In the general case, the lower the baud rate, the easier it is to generate.

If you’re still having trouble, I found that in LabView the default serial setup appends a newline character to the end of each string. You need to disable that in the VISA/Serial port configuration by setting the “append newline” to false.
