STM32F407 Dual DAC Independent Trigger Sources

Hello,

I have a problem for using both DACs of STM32F407 with independent trigger sources. What I did was directing DAC1 for Timer6 and DAC2 for Timer7 but they are still both triggered by one source (Timer6) and not independent as described. I set TSEL1 and TSEL2 for the sources accordingly (TIM6_TRGO, TIM7_TRGO). I tested both Timer Interrupts to be invoked as working.DMA is not used in my case.Are there any known issues for this topic?Thanks in advance, Sebastian.

If you're not using DMA, why are you triggering the DAC's from timers?  What is it that you're trying to achieve?

Are there any known issues for this topic?

Haven't heard of any, and don't plan to independently verify. If you want someone to review the code for errors/issues, you'll want to post a sufficiently complete example.
