Hello, 

I am using NUCLEO F429ZI. I am using TIM9 with 2 channel,  channel 1 use for input pulse counter, and channel 2 is output channel to generate a timer based pulse. I try to set TIM9 as master timer using TRGO. My goal is to use TIM9 to start TIM3 for my task, but TRGO signal on TIM9 will be decided by the number of pulse on TIM 9 CHANNEL 1 (INPUT CHANNEL), and input pulse number can be adjusted according user's setting. I am not sure how to set them.

anybody can help?

Thanks

channel 1 use for input pulse counter, and channel 2 is output channel to generate a timer based pulse.

You can't do this in one timer. There is only one counting element; you either count external pulses or you feed it by internal clock to generate a timer-based pulse.
