Hi All,

I would like to know how to set up GPIO and Its Interrupt for following purpose;

GPIO is used for light emission detection.

GPIO inputs some signal through ADC or directly.

GPIO triggers an interrupt which interrupt service routine works some duration time calculation.

I might understand entirely how to setting up, but I do not understand how to write such the code in detail.

Please tell me the coding with step-by-step like explanation.

Best Regards,

Takano

Hi Takano-san,

You can refer example code based on GPIO configured as external interrupt. You can find the same here:

Regards,
Gautam

Takano-san,
The example code pointed out by Gautam has all the code you need. You could use that example as a starting point and easily modify it.
