Is the firmware for SRF04 - Devantech ultrasonic ranger available ?
I have seen the schematic on the Devantech site, but unable to locate the firmware to make it work !
Can the firmware from the PIC on the SRF04 - Devantech ultrasonic ranger be read out ? Or is it code protected ?
Has someone tried making a clone of (...)

can some one please tell me how i can measure beyond 255cm i2c mode with the SRF02 ultrasonic ranger?
I can read the LOW byte but reading the high byte seems confusing....or can i only read upto 255cm? it does not say anywhere on the data sheet
i have observed that when lowbyte goes beyond 255, then the highbyte goes to '1' othe

i have an ultrasonic reciever written on it AND the transmitter .
I couldnt know anything about it because i couldnt get the datasheet .
am going to design an ultrasonic ranger using pic16f877a and some amplifires

Anyone implemented parts fo this excellent project ?
I plan to implement, but I am facing problems in finding ultrasonic sensors in my area.
Do you know good distributors for them in any area?

Can somebody explain to me the sample code here -> link.
Particularly in this line:
for(i = 0 ; i < BUFSIZE ; i++) // for all samples in buffer
cm += buf ; // add to sum
cm /= BUFSIZE ; // average samples

I was looking for how to interface the ultrasonic rangefinder with AVR and from a website i found the following steps
ultrasonic Range Finder Interface.
These modules are designed to be used for microcontroller based applications hence optimized for it. The interface is a single pin called SIG (signal). The MCU is connected to the (...)

Now I'm trying to make my robot and this is my first time...
I have Servo and I'm trying to control the servo with Ping)))... so the robot can stop...
But I met alot of trouble with Ping)))...
Can anyone give an Advice or help me, How to use Ping))) with AT89S52...
if necessary I need the "ASM file" cause I'm using Assembly language...

But is there no way of rather detecting the intensity of the reflected light and using that information to determine distance.
You can use the reflected light intensity only if you always approach the object at the same angle.
IMHO, an ultrasonic ranger is easier to build from scratch than a triangulating IR ranger

I am working on the "ultrasonic range finder".. in this I have to calculate the distance of the obstacle using ultrasonic sensor.
In this case, I am stuck with the problem,
If there are more than one obstacle in path at different distance, how to detect them with one sensor only & how to calculate the distance of each & every obstac

A good suggestion at the wrong place. AD620 has a signal bandwidth of about 10 kHz at G=1000, not particularly suited for ultrasonic, I think. You actually need an amplifier with a higher gain bandwith product to realize G=1000 for e.g. 40 kHz. Using a two stage amplifier is the most simple solution if you depend on easily available standard

Does any have C code for PIC 16F877a with the SRF05 module that has a pulse output proportional in duration to the range distance. I suspect this uses the capture mode.
Here is a fairly good tutorial:

Unlikely that you'll get that much range out of a simple IR set. Ultrasound is probably the better way to go for that distance.
Some options here. I worked on a robot for a class that used #2, the Seeed ranger.
