Hi everybody!
I've been running both the Polaroid sonar sensor and Vector 2x digital
compass on the HB without the expansion board. I'm using Kent
Farnsworth's older sonar driver code that is designed for the motor driver
output ports (U11). The digital compass is connected to the SPI port
using Tom Brusehaver's code. (Great work guys!)
Now, with the expansion board, I can do the same and have both sensors
work, but the wiring is messy and I can't take advantage of the
Polaroid header on the expansion board, not to mention I'm out 2 motor
driver ports. Has anyone tried to interface both sensors on the expansion
board through a different method? Perhaps some way of using the SPI port
for both sensors?
I'd appreciate any comments or suggestions. Thanks in advance.

BTW, this list is great!

| (...) I have started working on an expansion board version of the compass code. I won't have it done before fall probably (unless is snows or something really bad). I am involved in another huge project right now. My thoughts are to have the compass (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

| You misunderstood my point, or maybe I was not clear enough. I know the smooth PWM algorithm are available for I3.2. What I require is all the source code that's running on my handy board to be available. It's not the case for IC3.2, so I'm not (...) (25 years ago, 15-Apr-99, to lugnet.robotics.handyboard)
