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...

HiDoes ST offer a microcontroller capable of directly measuring 4-20 mA DC current?
Hello,I am working with:NUCLEO-H745ZI-Q => STM32H745ZI-QZIT6U => 144-LQFPRM0399 Rev 4DS12923 Rev 2AN 5354 (Getting started with the STM32H7 Series MCU 16-bit ADC) According to DS12923 Rev Table 96 note 3 is that Table 96 values:"These values are vali...
When I use the UART_Printf example to output an array of size 1024 (or larger) via printf, the program seems to freeze and doesn't output any information after being downloaded to the STM32WB55 Nucleo board. However, when I reduce the array size to 6...
I try to build a code example where I can execute directly from external OctalSPI flash.I use HAL project "XSPI_NOR_MemoryMapped_DTR" as reference and starting point:It works fine: I can write (flash) and read back external QSPI memory. I can also ex...
Hello,I have a problem with STM32N6. When trying to access any TCM (ITCM/DTCM) the CPU immediately crashes to the Hard_Fault. Do the TCM memories need to be explicitly enabled or something? From my experience from STM32H7, it was never needed. I've l...
Hey, I'm having some issues with setting up clocks for my STM32F411CEU custom board with HAL.Using PLLCLK from HSI ends up with Hardfault, around where RCC is being configured.The only way I don't get hardfaults is:1) if I set System Clock Mux to HSI...
