delayed PWM with variable delay, variable period and variable pulse width

Hi,

I just started to work with the NUCLEO-F767ZI. I'm not familiar with embedded programming.

For a new project I want to use the development board STM NUCLEO-F767ZI. An input signal will be used as a trigger signal. A certain delay (100us ... 200us) after the rising edge of the trigger signal a PWM signal with a puls width of 250ns...400ns and a period of 50us...10ms must be generated at an output pin. The delay time, pulse width and PWM period should be adjustable at the start-up of the test.

In a second stage the output pulses (250ns...350ns) should be modulated (50% duty cycle, 40ns period). So instead of a pulse of 250ns...400ns, 6...10 pulses of 20ns on - 20ns off

Can this be done with the STM32F767? Can someone help me with this?

Thanks!
