FRDM-KL25Z and multiple hall sensors

[rajakumar]

Hi All,

Requirement :

Count the pulses generated by hall sensor inside a flow meter.  The hall sensor produces around 330 pulse / second.  There would be around 6-10 flow meters connected to a circuit for calculating the total consumption.

Is frdm-kl25z my best bet to start this project or is there any other better alternative available.  

I am thinking of using the GPIO pins in interrupt mode to count the pulse.  Can multiple interrupts work without data loss parallely. Can the MKL25Z128VLK4 MCU handle this.

Hi, Rejakumar

Yes, You can use MKL25Z128VLK4(TPM function/GPIO function) in your application.

Hope my reply can help you.

Best Regards

Paul

Hi Zhe Tian,

Thanks for help.

Just ordered the FRDM-KL25Z kit.  Will update once I have it working.
