If I recall correctly, I think the BINH in the sonar software is set high for the entire duration of the ping. This way, ECHO will never trigger. If you tie your BINH to GND, it will enable ONLY the internel blanking. ---...--- ericson mar Master of (...) (28 years ago, 9-Apr-97, to lugnet.robotics.handyboard)

I am going blind reading the archives for the solution to this problem so I will just ask. Ive got a Radio Shack tin can IR reciever plugged into digital(7). An High output IR LED w/ current limiter resistor in series (LED was getting quite warm) (...) (28 years ago, 9-Apr-97, to lugnet.robotics.handyboard)

Please excuse my bitwise ignorance. Could someone explain this statement to me. if (4 & peek(0x1000)) what does peek(0x1000) return? what is the 4 for ? and what does the "&" compare? thanks victor (28 years ago, 9-Apr-97, to lugnet.robotics.handyboard)

(...) Remove the BINH and check the sonar readings...the minimum distance it can read will be about 16-17" (this is with an internal blanking OF 2.38millisec) this time can be modified by adding a resistor to the BINH. Also the ECHO goes into the (...) (28 years ago, 9-Apr-97, to lugnet.robotics.handyboard)
