Conversion of ADC1 and first channel of ADC2 will finish theoretically at the same time.

Thank you!

I want to start from 0 phase shift to 180 phase shift.

Sorry, that is what I should do:The problem is that the MOSFET gate is connected only at CH1, CH1N, CH2, CH2N. When I projected the system I didn't known that I need soft-start for H bridge.

Thank you for response, but that doesn't help me...Another idea is to generate a pwm signal in edge aligned mode with the HIGH period set by some CCRx registers and other pwm signal to stay at the same limits. Is it possible?

Hello! I want to trigger with timer the ADC to convert with interrupt or DMA but my program stops at the adress 0xfff4ea. I did all the settings and I introduced the callback function in main. I think it's a problem with this callback. What is wrong?

Hello! What is the difference between output compare and output compare no output in Cube IDE? Can I use output compare no output to trigger ADC?

Hi! I m using uC STM32G491 and I have 2 ADC triggered by TIM1 CCR3. First ADC1 converts 1 channel and ADC2 converts 2 channels in scan mode. How can I know in which JDRy registers it will be stored each conversion result?

Hello! I m using uC STM32G491 and I want to use CH1 and CH2 from TIM1 for asymmetric PWM to command a H bridge. In RM says that I must use CH1 and CH3 (oc1refc and oc3refc) and nothing about CH1 and CH2. Can I use them?

Hi! I m using the uC STM32G431 to drive a H-bridge. I saw that the reset value of GPIOx_PUPDR for PWM pins is 0 which means they are in state "no pull-up, pull-down", so they are floating. I m afraid that they could activate the driver of MOS. What to do?
