"Randy,
The I2C is a trigger operation only. There is no free run operation. You can click this link to view the datasheet which covers all the timing and I2C part…"

"@Andrew,
That sounds really good. So the sonar is going to be smart enough to only ping when we ask it? I suppose it probably has a continous and on-demand mode. I'd expect the on-demand mode would need a…"
agmatthews commented on Carl Myhre's blog post I2CXL-MaxSonar®-EZ™ Sensor Line Released!"@Randy,
I've now got my I2C sonar code working with the 2.71 code (ie with the new i2c.h library).Using i2C sonar may allow us to get back into collision avoidance - I'm thinking using sequenced sonars to ping in turn (to avoid intra sonar…"

agmatthews: We do not have any distribution at our distributors yet. We are in the process of notification of the distributors. You were the first to know :-)
Randy: The shielded cable is not…"
MaxBotix Inc commented on Carl Myhre's blog post I2CXL-MaxSonar®-EZ™ Sensor Line Released!"Jack,
Thanks for your inquiry. Deadband generally is not a word that can be used when describing a Maxsonar product. For example these I2C sensors detect objects from within 1 mm of the front sensor face, and objects closer than 20 cm are…"
Jack Crossfire commented on Carl Myhre's blog post I2CXL-MaxSonar®-EZ™ Sensor Line Released!"So how did you get the deadband down to 20cm?"

Good to see a quality sonar with i2c interface direct from a manufacturer
I've recently been trying to compile my original i2c sonar code into…"
Michael Pursifull commented on Carl Myhre's blog post I2CXL-MaxSonar®-EZ™ Sensor Line Released!"and if PWM wasn't a blocking call, we might be using it. I use PWM in other applications of these sensors when that is not an issue. I've had success driving several of these sonars from a mini, for example, and connecting the mini to an…"
Andrew Radford commented on Carl Myhre's blog post I2CXL-MaxSonar®-EZ™ Sensor Line Released!"Don't see why shielding is necessary, cap still might be though.
I think the only reason shielding is necessary currently is the numpty use of the analogue voltage signal from the sonar units. There is already a PWM output which would in…"
Michael Pursifull commented on Carl Myhre's blog post I2CXL-MaxSonar®-EZ™ Sensor Line Released!"I will, if I get my hands on one.... I sort of blew my budget already this year on MaxSonar, several hundred dollars in the last round of purchases, but we did get the HRLV added.... and the new PX4 gear didn't help my budget either...…"

"I forgot to mention on the APM2 we have a little I2C port on the back right of the board which could be used although it's a bit of an unusual 4pin connector.."

"Carl,
Very cool.
Do you think this reduces the need for the shielded cable and/or power smoothing cap/resistor pair as shown on this web page?
Anyone feel like taking a stab at writing…"
