i'm trying to use this sensor with an pic18f4550 and ccs compiler.

can anyone help me with this?


Where in China do you live ?

Would there be shipping costs to Shanghai? And what are the payment options?

I bought the Ultrasound kit and I was woundering what the PD7 is for...

 Has anyone got this working on there Bots? i'm a bit confused on how its going to work... The OC2 sends a fixed impulse from the microcontroller and when Q1 receives it  ADC2 will get what kind of signal? Am I supossed to use a ADC on the microcontroller or a timer?

 I'm sorry if its a lame question but I still haven't tested it yet and i'm a bit confused on how the info is treated in the microcontroller.


Funny that this post got bumped by someone else today. I was just reviewing it, with the thought that I can either get this working on the Arduino or the TI LaunchPad, both of which I recently acquired. I've had this kit sitting around for a while, just waiting to be used.

Has anyone code for working it with the Arduino?

I've code for an ATmega8, with some modifications (different registers) it should work on Arduino too. I've been using this sensor on an Asuro robot, here. Need some time to search for the sourcecode.

Cool. If you find your code, can you update your robot page with the code attached? That way everybody gets to see it if they want to.

Code is attached to my blog entry.

I tried to port the code to Arduino with no luck. You can find the sources on my Google code page
