how to change the range in the SRF08 ultrasonic?

eddiech

hi,

I have a problem with changing the range in SRF08 ultrasonic rangefinder.
Here is my code. I want to reduce the range. Are there any problems in my code?
I use CCS Complier to complie. Thank for any reply.

·· i2c_start();
·· i2c_write(address);
·· i2c_write(0x00);
·· i2c_write(0x51);

·· i2c_start();
·· i2c_write(address);
·· i2c_write(0x01);
·· i2c_write(0x00);

·· i2c_start();
·· i2c_write(address);
·· i2c_write(0x02);
·· i2c_write(0x01);

·· delay_ms(70);

·· i2c_start();
·· i2c_write(address+1);
·· i2c_read(1);
·· rangehigh = i2c_read(1);
·· rangelow· = i2c_read(0);
·· i2c_stop();

Sorry we haven't responded earlier.

1: I haven't used the SRF08 personally.

2: Why would you want to reduce the range?

3: This is a Parallax PBasic forum, not a generic PIC CCS forum. Go ask them.

Actually, one can post anything in "the Sandbox" (that's its purpose) but to your point, one might get better service going to CCS or to Daventech (the makers of the SRF-08, a product that Parallax never carried).

Whoops!· Forgot to mention I move the thread to the sandbox from the Robotics Forum.·

I'm really sorry! I made a mistake. I thought·the SRF08 is Parallax's production. I feel sorry for my carelessness.
I had solved my problem.·Thank you!
