Hi Team,

How to configure the SPI clock speed SCLK=50000 Hz for a master (clkSpeed parameter in the function wiced_hal_pspi_init()) when the CYW20719 uses a 24 MHz crystal oscillator (XTAL)?

We need SCLK=50 kHz for communication with a specific pressure sensor. In the existing FW (WICED 6.2) is not possible to set the SPI clock less than 187 kHz for a master (limited by FW).

Thanks,

Ruslan

Hi Rulsan,

You are correct , you can't configure the SPI clock for 50kHz. The minimum you can set is 187kHz.

Thanks,

Anjana

Hi Anjana,

What about synchronize the SPI with an internal oscillator. Can we?

Thanks,

Ruslan

Unfortunately, that would not be possible.
