Hello All,

Is it possible for the STM7x family to drive PWM outputs - specifically here TIM1 and TIM8 - in Low Power Mode?Thanks,John W. #stmf7-lp-pwm

Hi,

Yes, It is possible to drive PWM outputs.You can refer to the

http://http://www.st.com/content/ccc/resource/technical/document/reference_manual/group0/96/8b/0d/ec/16/22/43/71/DM00224583/files/DM00224583.pdf/jcr:content/translations/en.DM00224583.pdf

for more details and section ''25 Advanced-control timers (TIM1/TIM8)''.Regards

Yes, and, where, specifically, is the discussion about running PWM in low power mode?

I see in chapter 29 - the LPTIM can be run in PWM mode; but what about TIM1/TIM8?Hence the original question.  Thanks,John W.

Specify ''low power mode'' first.

As long as there is power and clock supplied to timers, they work. There is nothing ''low-power-specific'' in the PWM modes of Timer. Review Table 12. Low-power mode summary in RM0385 rev.2. Note the RCC_APBxLPENR registers in RCC. JW
