Hi everybody,

in the datasheet of the STM32L073VB, it says there is no advanced timer with complementary PWM output. Still we need two complementary outputs, very simple without delay function. Is it possible to use another timer, or to do it via an Interrupt, or.. ?

Maybe somebody has an idea?

One timer, two channels, one configured in PWM1 and the other in PWM2 mode?

Hi M. Schmid,

I suggest in this case, you can use to timer synchronized to start together ( interconnected via a TRGO signal which with the master enable the slave to start at the same time). The slave has the same parameters as the slave , except the polarity wich is inverted.
