Can someone help me in creating this code for zilog.??
I have an Arduino codes for this project but I can't understand how to modify this codes for using ZDS II.
Please help me... This is the code for arduino..


Ultrasonic sensor - Distance Measurement with arduino

# Define echoPin 2

# Define digit_4 12
# Define digit_3 11
# Define digit_2 10
# Define digit_1 9

for (i = 5; i <12: i + +)

}

}

void segment_write ( int digit, int value) {

if (digit == digit_1)
{

digitalWrite (digit_2, LOW );

digitalWrite (seven_segment_A, ((value & 0x01))? HIGH : LOW );

}

digitalWrite (seven_segment_D, ( (value & 0x08))? HIGH : LOW );

digitalWrite (digit_4, HIGH );

digitalWrite (digit_4, LOW );
}
}

This looks like generic code for another purpose.

I have a distance module I haven't looked at yet. I think to start something like this, a schematic and datasheets are needed for the modules involved. Knowing where and how things are connected is required to control them.

Zilog makes processors and Arduino is a project board with one of a few different processors. ZDSII from zilog is available for many of their different processors.

Thanks for the advice mr..
my zilog is z8f042ahjsg

I want to use it as a distance measurement using an Ultra sonic sensor.. and will be display the distance in the 4 7 segments..
Thats as what I want to display...

I just don't know how to start my zilog codes...
I already have the ZDS II software..

Look here for some sample application notes and source code "www.zilog.com/index.php?option=com_doc&Itemid=99"

Be sure to select Encore! / Encore! XP at the left to narrow the results for your processor. I thought AN0191-SC01 looked like it might be easy to study.

*Dear mr:

I think he's going to use Davantech SRF04 sensor or Parallax PING))) sensor or for his measurement, that are used here and here respectively.


*Dear graceshin00:

Does your trouble mainly concerning to a measurement part, a display part or both?

The sensors above are intelligent modules. They begin measurement by asserting a start pulse and they return a result pulse which width indicates the measured distance. The pulseIn() function of Arduino returns measured width of a pulse.

You can measure the duration of the result pulse if you can handle a timer thoughtfully. Especially in Z8, a Gated Mode of a timer module is more useful for you to measure the duration.

If the timer module is unfamiliar to you, I weakly recommend you to use a software loop as the easiest way.



The function returns a value which is directly proportional to the pulse duration.

If you want your Z8 to run another task like a robot control, I strongly recommend you to use Gated Mode of the timer.


*Attn: everyone

Hi!

Does anyone know ultrasonic-based range sensor that outputs analog voltage related to the measured distance? As mr insisted, I also think it is the most easiest way to apply AN0191 if he want his Z8 to run another task while the measurement. I found I²C-based range sensors, but I couldn't find an I²C in Z8F042A.


*Attn: Zilog

I think there's no updated I²C application note which is applicable to Encore XP series (premium peripheral set) -- e.g. ACK has been moved to I2CSTATE. I recently saw the question related to new I²C here.

Thanks for the help mr..

Thanks Tomohiro..
But I'm just new in programming
i just dont know how to use codes in zilog..

I really need a codes for my project to develop.
