Did you find the solution?

Any help??

Hello,

Which result did you get?

Did you try to run the hex file which I sent?
The example works between 450mm-1300mm, so please try to place an object for example on 800mm and try to move it slowly.


Kind regards,
Jovana

Dear Jovana,

i tried also but it doesn't work. It stuck in

Code: Select all

if(distance > _ULTRASONIC2_MIN_RANGE)

And distance is always lover than.
I tried to debug it and seems sensor doesn't answer correctly.

Without a deep reading of the datasheet of the sensor is impossible to understand the issue.

Some question :

I need to power the PIC from 3.3V or 5V? On the click module is written 3.3V
What about enable pin and test pin? Both are pull-up in the click board. I need to set low in some moment?
I tried your .hex but still no correct answer...

Thanks for the answer.

I've tried your code but also for me it is not working.
It stuck in :

Code: Select all

if(distance > _ULTRASONIC2_MIN_RANGE)

Distance is always lower than ultrasonic2 min range. Also if i move my hand in front of it.
I've check and seems no correct distance back from the sensor... Is possible that we need to use TST or EN digital?

Is the board working with 3.3V digital output or 5V ?

I've check also with some logic level reader and sensor answer but wrong reading.



Can you help me?
