PSoC4 with UltraSonic Sensor HC-SR04

[ShVy_264716]

Hi All

   

I need to interface and utilize four Ultrasonic Sensor Modules HC-SR04 with the PSoC 4 Prototyping kit CY8CKIT-049 42xx. I want to do it using pin interrupts. Can somebody please suggest a method for this? Thank you in advance.

There is a single interrupt for a port on which several pins can be enabled to generate the interrupt. You will have to read the pins/port to decide which one did fire the int.

   

See attached for configuration.

Hi Bob

   

Thank you for reply. I have checked the project shared by you. I need help in programming the entire functionality. I mean I need help in defining the Timer/Counter and Pin interrupts for four Ultrasonic Sensor Modules. Even if given for only one module, it will help me a lot. Thanks in advance.
