How to set the clock source for TIM3 We are trying to use TIM3. We also want to use an external CLK as the clock source for TIM3, but we don't know how to set it. .ioc file - Where should I change the TIM3 clock source settings?

We are developing a device using the STM32H743.We are setting up the GPIO during initialization, but I am wondering about something.What is the GPIO output before initialization? Is it high impedance?Or does it change depending on the circuit connect...

We are developing software that uses GPIO interrupts.We would like to test if the GPIO interrupt handler is working properly, but is it possible to set the pin assigned to the GPIO interrupt High/Low in software?Is this only possible by inputting a s...

We are using HAL_SPI_TransmitReceive to transmit and receive SPI data.We would like to cancel HAL_SPI_TransmitReceive midway through. Is this possible? Also, how should We write it?

We are performing SPI communication using DMA.In this case, we manually set the GPIO to High/Low as SPI_CS, but (obviously) SPI_CS goes High before all of the SPI CLK is sent.How can we manually return SPI_CS to its original state after all of the SP...

That was a very easy-to-understand answer. Thank you.If I select Internal Clock, what will be the accuracy and error of CLK?

The MCU we are using is STM32H743ZIT6.

Thank you for your reply.I understand the specifications now, so I will close this.

Thank you for your answer. I see, analog input!Is it floating as an electric potential?

Thank you for your answer.I see, that's right.Is this the same idea when using HAL_SPI_TransmitReceive_IT, which is not blocking?
