Esp 32 using HC-SR04 PROBLEM

[daddytims_tims]

Hi All

I am currently working on SR04 project that requires an esp32.
It works with the Pic18f1320 and Pic16F648A.

However, I am not getting any readings, when using the esp32 with the Sr04. it ONLY return 9999.
How can this be resolved?

I need some assistance as it regards to this project.

I attached an example file below

Hello.
The properties Use Timer Interrupt, have you tried selecting No instead of yes?

The timer for ESP32 will be investigated.
Thank you for letting us know.

Hi martin
No, I didn't select "No", but I just did, another test with 'NO' and the result were 1 then it jumps back to 9999

AS the distance measured is 5.5cm, I would expect the result to be between 5 & 6
