HCSR04 on BeagleBone doesn't work about diozero HOT 9 CLOSED

Ok, I think I know what the problem is. The library defaults to the sysfs provider; I guess it is just too slow. I will create a new wrapper project around this C library (https://github.com/VegetableAvenger/BBBIOlib/tree/master/BBBio_lib) that uses direct memory writes rather than sysfs. Will let you know once done, won't take long.

Sorry for the delayd response. I'll look into this today / tomorrow. What Java and diozero version are you using?

FYI I'm running:Linux beaglebone 4.4.36-ti-r71 #1 SMP Sun Dec 4 02:56:26 UTC 2016 armv7l GNU/Linux Just committed my changes and pushed a new snapshot build. Note I've not tested it yet, let me know how you get on.

And make sure you include diozero-provider-bbbiolib-0.10-SNAPSHOT.jar on the classpath. Regards, Matt

Excellent, thanks for testing and letting me know. Matt On Wednesday, 15 March 2017, 16:56, Arian Suarez <[email protected]> wrote: Appears to be working, Thanks!— You are receiving this because you commented. Reply to this email directly, view it on GitHub, or mute the thread.
