Kip, / Eric
Was just wondering how he might deal with many sources of PWM from many
processors / sensors.. with limited number of input capture resources?
Certainly one processor could time division multiplex (if that is the
correct term-- or serialize) PWM stream, but with many processors maybe there would
be a way to request a signal so as not to have redundant data missed by
receiving processor that is using a multiplexer tied to input capture pin.
Interesting a friend uses components designed for an automotive throttle
control that is exactly compatible with RC servo pulse 1.0 to 2.0 ms. (If I did
not mention)
Wonder what would be a practical frequency upper-limit for Eric's
application?
One thing that does scare me about using more complex forms of communication
such as I2C...
is you have to make sure you have carefully covered the bases to avoid
states that might hang up a system whereas with PWM or analog performance might
suffer if implementation is not perfect (free from noise...), but at least
typically you won't experience a crash. Just me talking.
