Communications via the Programming Port
Anticipating more autonomous stuff next year, I thought now would be a good time to develop the basics for an off-board processor.
In 2003 we used the PWM out and Analog inputs to communicate between the processor and the basic stamp. Decoding the PWM values to get an ~8 bit value and setting a hardware PWM to perform and DAC function to send ~8 bits back.
This year I would like to use the Programming port for two way communications. The question: Has anyone done that? And how/what was your algorithm? What processor did you use, etc.
Thanks.
