How to divide the 24MHz clock into 32kHz based the CYW920719Q40EVB-01 Evaluation Board.

[qzy_4727816]

Hello,

My application is based on the CYW920719Q40EVB-01 Evaluation Board. First, I need to define a GPIO pin, then divide the 24MHz clock into 32kHz, and finally output the 32kHz clock through the defined GPIO pin to external use. The problem is that how to use WICED-Studio-IDE to implement this function? Please provide some references and operation steps.

Thank you very much!

Hi qzy_4727816​,

You will need to configure a GPIO for output to aclk to get the desired frequency. Please look at /20719-B1_Bluetooth/apps/snip/hal/pwm demo example for more details.
