TIM9 doesn't have a repitition counter like TIM1/8 do. The only difference I can see is that PWM generation will stop after a certain number of periods (equal to the number of RCs) when I set the timer in One Pulse Mode. The timer 1 interrupt will interrupt after PulseWidth period. I use an STM32L4R5ZI. For example, one could use DMA in circular mode (or interrupts, if the sampling rate is low enough) to continuously fill a buffer large enough for your needs (double the needed samples?), then when the "interesting" part of the signal arrives, just DMA them out of the buffer in your working memory. It is useful for generating one-time events, such as triggering a specific action or producing a pulse for a fixed period. Each STM32 variant has several built-in timers. This means that both level-sensitive and pulse-sensitive interrupts can be handled. ADC with 4 channels, into DMA mode, for reading some analog input. The timing of the One Pulse is correct, but when the pulse is finished, the output was set to high. SMS). The pulse can start as soon as the input trigger arrives or after a programmable delay.
