Esp 32 using HC-SR04 PROBLEM

[Viktor74]

Hello, everyone! Could you please tell me what I'm doing wrong? The compiler gives an error. In the simulator it works fine.

Hello.
Thank you for the bug spot, it looks like there is a sharing violation of timer 0 when there should not be.
To get your project to work you have two options.
1. change timer interrupt from 0 to Timer 2 for example.
Or
2. Change properties of HC-SRO4 to Use Timer Interrupt = Yes.
Change the timer interrupt from 0 to 1 or 2 for example, then change Use Timer Interrupt back to No

I will look into fixing this component .

Thank you Martin! Yes, it really works great on Timer2.

Thanks Viktor.
I fing using the timer interrupt for HC-SR04, the results are more accurate.
I'm glad your project is know working.
Thanks for letting us know.
