Trouble use ComPort to read Parallax Servo Controller - USB
Julian800
Posts: 31
Hi
I need some Help.
·I am writing program in Delphi with ComPort Library to communicate with Parallax Servo Controller – USB. I can connect and write to Comport, but no reading back. Is that· I open Comport with wrong setting?· OR something I need setup for Comport properties? ··Thansk!
·Baud Rate:9600, Data Bits:8, StopBits:1 Part: None Flow Control: None
TABLE WAS SUPPOSED TO GO HERE

I also look CrustCrawler’s “Open Source Servo Control Software for the PSC”. It seems they also use Comport.
