HC-SR04 not working with ""Pic"" Anymore

[medelec35]

Hi Martin

I just tried. It still doesn't work. I copy the file to the folder updated it, try compiled but fail.
I restarted the win 11/ project It still fails.

I am using v10

That still looks like the old version and not the latest?
Can you go to Library updates and select Show up-to-date files and what version does it show for HC_SR04_Ultrasonic.fcpx?

I can compile now but the distance show random numbers.

That could be down to the Timer Settings property,
What about starting at say 1:1 for both, then just increase if still not working?
1:1 is not recommended for really fast clock speeds e.g. esp32

Hi.
That tells me I was correct.
When you add the fixed component to

Code: Select all

%ProgramData%\MatrixTSL\FlowcodeV10\Components

What you should see is:

Since it's not an official library update.
Did you restart Flowcode or reload your project.
Don't click on the Download after adding the unofficial component update.

Hi

Martin, I had click update during earlier part.

Since your last message, I follow on to that Now I got it to work.

Thanks, Alot

I will update you

With arduino.

No matter what I do when I use timer interrupt, the value is fluactuating. But if I "disable " timerinterrupt it work fine.

Thank´s Martin glad it working again.

Thank you, very much.

hi Jorgen.
Sorry it's the other way around.
With the Uno can you try with Timer 0 set to:
Prescaler 1:1024
Postscaler 1:16

Hi again Martin!

Yes, now it is stable, but the distance is max. 92 Cm.
