I read a lot about it for other STM32 MCUs but can't find any confirmation that it’s not possible to use PA4 and PA5 as GPIO output and DAC1 channel 1 and channel 2 internally for STM32F303CBT6. There's a hint in the errata of another STM32F303* usin...

Hi,I'm using the combined pwm mode using STM32L431 TIM2 and noticed this information in the reference manual RM0394, page 845."When a given channel is used as combined PWM channel, its secondary channel must be configured in the opposite PWM mode (fo...

Hi,I'm looking for an example schematic of a USB PD charger interface using STM32G071G8U. Current questions are:Is the available singe CC pad (PA8) all you need from the hardware point of view? Is there any option to connect D+ and D- to allow 5V loa...

Hi together, I’m trying to start a new project using STM32G031. The final decision of the MCU isn’t made yet and therefore I’m currently testing the possibilities with the Nucleo STM32G031K8 board. I’m using the onboards USB debug interface. I start ...

It's confusing, because the name of the errata describes that it's for STM32F303x6/x8 only. There is another one for STM32F303xB/C named ES0204 Rev 11 and there is no information that PA4 and PA5 are not working as specified. But I'm afraid that I c...

Right, but there are others that said that GPIO functionality is still given.

Hi TDK, Thanks, but PA4 don't work as well, do it?

Hi II,Thanks for your response. To make sure what I like to do. I use the DACs only as internal comparator input so not necessary to map to a pin. The GPIO PA4 is necessary to switch external hardware.

Thanks for your quick response. It's an OR I use and therefore it can make sense, at least for me. Think of a pwm output that get's the CC value from an external source but the timer shall limit the minimum duty cycle to a defined value. If channel 1...
