The article sounds interesting, but I am using sonars that have
predefined firmware that can't be changed by myself at the
present time.
Maybe later.
Thanks. It is an interesting paper.

Please log in for more thread options Well, thank U everybody, the question now is :
I'm using a 68HC11 MCU, how can I get the sonars output using the ICx
input ??
Do I need to use one "pin-per-sonar" or there's a way to get the data
without losing the direction (that is, the sonar !!) ??

You are using SRF04's, which don't have I2C output. This makes them
more difficult to use, but you can use them with the techniques
presented earlier in the thread.

All this method does it determine the order and timing of when a range is
started, which would be when you send the i2c range command to the SRF08. It
shouldn't require any firmware changes. You'll know when it started, and
you'll know when it ended by the value returned.
