"So, SMS is signicantly slower because it uses ASCII conversion ? Interesting. Even at high baud rates ?"
SMS is aimed at ease of use and precision. Although I am surprised to ear about SMS's and Pduino's speed problems. I made an installation with an SSC-32 servo controller controlling 24 servos connected to PD. The SSC-32 is based on the SAME chip as the Arduino and uses a communication protocol VERY similar to SMS and I never experienced any problems. Maybe you are not keeping your messages simple enough? Or maybe the big difference was that I was using a hardware serial port and not a USB>Serial chip/converter. Tom On 6/21/07, Alexandre Quessy <[EMAIL PROTECTED]> wrote:
