Post Multiple Ultrasonic Readings
I've been trying to read the other 7 ultrasonic readings that are available in the I2C mode of the Lego Ultrasonic Sensor.
The program works like a charm when reading the "first" value at 0x42. However I always receive a zero when I try any of the other addresses which supposedly have the other values, like 0x43, 0x44, etc...
Has anyone managed to do this successfully on RobotC?
(I'm using version 1.05, and it's associated firmware, because 1.10 is too buggy for other things I need to do.)

-Kit.

Yes. I've had it working.

It's very possible.BUt you have to write your own driver and set the sensor type to "I2Custom".

And the setup for the sensor is different. I think you have to send it a different mode byte to set the sensor into this type of mode. I can't recall whether you have to set it in "single shot" mode or can set it up for continuous polling. But thie is all covered in LEGO's SDK.
