How to modify the frequency of the host to a desired value for 52832 SPI,such as 20M.

[shai735]

I am using SPI for communication (52832 as the master and esp323c as the slave). The spi frequency of esp323c is set to 20M, while the spi frequency of 52832 can only be set to 2,4,8,16,32 in the structure. Can I change the spi frequency of 52832 as the master to a specific value, such as 20M.

Please can someone give any suggestions? Thanks.

esp323c as a Slave surely accepts the nRF52 SCK whatever the SCK frequency generated by the nRF52 Master? Master Mode on the esp323c can additionally be set to any of the nRF52 frequencies, not just 20M, in case it has some unusual requirement, unless the esp323c code is not available ..

Suggest just try nRF52 Master to esp323c Slave, it should just work regardless of SCK setting.
