TimHandle.Instance = TIM1;

TimHandle.Init.Period = 10;

TimHandle.Init.Prescaler = TIM_CLOCKDIVISION_DIV2; // LOOKS VERY ODD

TimHandle.Init.ClockDivision = 0;

TimHandle.Init.CounterMode = TIM_COUNTERMODE_UP;

TimHandle.Init.RepetitionCounter = 0;

What's the trigger 50 MHz / 11? 4.54 MHz?

Hi Chris,

there is no such section in the F7 Reference manual right now (Rev. 2).

Hi Clive,

you are right the timer frequency was much too high.

But setting it correctly does not change anything regarding the interesting effect.

I think I have to go for a workaround and cancel the search for a real solution.
