STM32CubeIDE PWM Mode1/2 are missing when the channel is configured in Output compare

[juvann]

I have a board Nucleo WB55 and I'm configuring PWM on channel 1 of TIM2.

I know is possible configure PWM Mode 1 also on channels configured as Output Compare, but CubeIDE not allow set this configuration, I think is an issue.

I changed the init code with TIM_OC_MODE_PWM1 and works.

PWM1 is simply a variant/superset of Compare mode; software-wise it is simply compare mode, it just controls the hardware output differently. You may configure PWM mode and keep the output disabled - then there is no difference between these two modes.
