Hello Brian and All, Thanks Brian for the additional information. When I use "NXTCommand.setVerify(true)", the ultrasonic sensor seems to work fine on a Mac. I managed to port my localization lab to icommand yesterday and everything seemed to work. (You can see the RCX-LeJOS version at http://www.mcs.alma.edu/LMICSE/LabMaterials/AI/MonteCarloLoc/MonteCarlo.htm - NXT version still to come.) So thanks again.
However, the getDistance command doesn't work without "NXTCommand.setVerify(true)". I did try to the for loop idea, and all I get are error messages and returned values of zero. So obviously there are some Mac-related issues there. But with "setVerify" I am all good for now... ...Myles > Date: Fri, 10 Nov 2006 17:38:19 -0600 > From: "Brian Bagnall" <[EMAIL PROTECTED]> > Subject: Re: [Lejos-discussion] Ultrasonic on the Mac > To: "leJOS Discussion List" <[email protected]> > Message-ID: <[EMAIL PROTECTED]> > Content-Type: text/plain; format=flowed; charset="iso-8859-1"; > reply-type=original > > Hi Myles, > > Sorry if my short answer sounded abrupt.
