GPIO Interrupt using for optocoupler in PORTE PIN2... This port don't have a digital filter in Hardware.... how to apply software (FIR or IIR) filter...
Please Help me....
Advance Thanks
Hi,
I would recommend to download MCUXpresso SDK software package.
The SDK software package includes CMSIS DSP library, which provides FIR example with below path:
..\SDK_2.5.0_FRDM-K66F\CMSIS\DSP_Lib\Examples\ARM
Wish it helps.
Have a great day,
Mike
