setClockSpeed()

fl::optional< fl::task::Error > fl::spi::Device::setClockSpeed

(

u32

speed_hz

)

Update clock speed.

Parameters

speed_hz

New clock speed in Hz

Returns

Result indicating success or error

Note

Runtime updates not yet supported - new speed takes effect on next begin()

To apply immediately: call end() then begin()
