It looks CYW20706 has GPIO input hysteresis feature.

    ----------

    wiced_hal_gpio_configure_pin()

    ----------

    // Input Hysteresis

    // GPIO configuration bit 13, hysteresis control

    GPIO_HYSTERESIS_MASK         = 0x2000,       

    GPIO_HYSTERESIS_ON           = 0x2000,

    GPIO_HYSTERESIS_OFF          = 0x0000,

    ----------

Is it able to set for each GPIO pin separately or for group of several pins ?

Here’s the info we have:

20719 –

20706 – below is hysteresis table

For 706 also you may go with he spec value 200mv

Thanks,

Hello,

The API wiced_hal_gpio_configure_pin() supports setting the bit 13 for hysteresisAPI allows you to set configuration per pin.

Hello Anjana,

Thank you for replying.

Could you let me know the threshold voltage of High/Low with hysteresis ?

And how about CYW20719 ?

Best regards,

Mizuno
