Question

stm32H7 with DAC904 speed limit

Hello to the STM32 Community,

 

I am trying to connect a fast TI DAC904 to a Nucleo board with H743. I am using it as a single M7 core. I have built a project with CubeMX where:

Timer1 -> DMA -> FMC -> DAC904

Short sine buffer in RAM-D1 and DMA as circular buffer

It works but I am getting maximum speed of 12.6 MSps.

I have tried to modify the timer frequency but I am getting a limit at that speed

Is there a way to make if faster?

Thank you

 

Benny
