STM32F4 SPI Circular transfer

[CsZoli]

Dear All,

I'm stuck with the following task:
Would like to send 3 fixed byte value to the SPI bus but ~1000 times sequence (without for loop or large buffer if possible).
Is it possible somehow with circular DMA or any other clever / efficient way?
Please advise.

Many thanks
Zoltan

Hi,

The SPI driver has a circular mode, see the configuration structure, however it is not possible to send an accurate amount of data, it goes until explicitly stopped.
