Resolved! In what document can I find a table as to what peripherals are directed to which I/O pins? Am am currently working on the STM32446RE but have not found it for other chips either.

For instance What pins can UART1_TX come out on? Or what peripherals are attached to PA5?I would think there was a table somewhere. I have looked in the RM0390 Reference manual but they say Alternate Function 0 - 15 but do not say what the alternate ...

Detecting current ADC channel in Analog Watchdog Callback

Hi there, this is a question referring to one old post, as I do not know if any solution was found for it or if anything changed after these years:https://community.st.com/s/question/0D50X00009XkY1mSAF/detecting-current-channel-in-adc-interrupt-callb...

STM32H747 dual core read/write to the same SRAM behave strangely

Hi,I am playing with STM32H747 dual core. I used the example code in DISCO. I am able to bring up the two cores and light up the LEDs from both cores without problem. HSEM also works fine.Now I am trying to write data to SRAM (0x10000000) from one co...

How do I cascade the output of TIM1 into HRTIM count?

I need to use the HRTIM for it's 10 phase synced outputs, but at a lower speed than what pre-scale and period can cover.I have TIM1 producing the base waveform I want, and now I need HRTIM counts to be based on that, instead of the CPU clock. I found...

STM32F7 QSPI wrong read data

Hello!I am going to use stm32f722vc MCU and QSPI in my design. Before designing PCB I research QSPI on available hardware: board with stm32f722vc MCU installed and all GPIOs available on headers. I am trying to execute indirect read mode to fetch GPI...

Generation of an event at 40 Mhz

Hello, I would like to generate an event at 40 Mhz or every 25 ns. I have an algorithm that generates a very particular square wave shape. That's why I can't use PWM or DMA transfer. I use a STM32F769. Thank you for your answers.
