STM32F767 SPI SLAVE DUMMY CYCLES AND FREQUENCY RELATION

Hi,

I am using a STM32F767zi nucleo board as  SPI full duplex slave. The dummy cycles of the slave device is varies in accordance with the master frequency change. How can I handle the dummy cycles independent of master frequency? What is the solution for making fixed dummy cycles for various master frequencies?

Thanks and regards, 

Arjun

you set: SPI full duplex slave , so all clock/cycles coming from master, you cannot change any clock on slave side.

you need to change at master.

I don't need to change the frequency from the slave side, I have to make the dummy cycles needed for the slave  independent of input master frequency.
