Is it possible to use pb8 (boot0) as I2C1 SCL pin, it seems STM32CubeIDE let's me configure it that way. But how can I prevent issues with the boot function after reset? Since I2C is pull-up level, right?
Hi All,I want to design USB schematic for STM32F105VCT6. I read Introduction to USB hardware and PCB guidelines using STM32 MCUs(AN4879) and it said that STM32F105/STM32F107 has Pull-up resistor on USB_DP line.Question 1Can I design USB schematic wit...
I want a stable version sys_arch.c and sys_arch.h based on µC/OS-III, LwIP only provide example for FreeRTOS.I found follow example, please help to optimize it, thanks #define SYS_ARCH_GLOBALS /* lwIP includes. */ #include "lwip/debug.h" #include "...
Suggest the the product STM32F407VET6 is Fake or Not .. How to find fake products . The lables are not as per in Manual .
How do you call an interrupt hanlder as a result of an interrupt (like systick) in the STM32F4xx library? Do you have to change the value in the vector table to point to the handler manually or how is this handled?
I am trying to use the backup SRAM but get a hard fault when writing to the memory. I have unlocked the backup domain, enabled the backup regulator, and enabled the clock. What other step am I missing? // unlock backup domain HAL_PWR_EnableBkUpAcce...
Hi,I'm currently using the STM32G474RET6 controller for my application which makes use of the CORDIC coprocessor. I'd like to perform logical operations (say comparison checks) on the results from the CORDIC coprocessor using an external peripheral, ...

I have a Nucleo 144-pin F746ZG and I want to configure the user button (PC13, pulled to ground according to MB1137 schematic) to toggle an onboard LED on a falling edge via EXTI interrupt.I am using this sequence to initialize the interrupt handling:...
AN2606 Figure 115." Bootloader V9.x selection for STM32U595xx/99xx/A5xx/A9xx" show that the Bootloader USB detection aborts DFU startup to a system reset when no quarz is found. Does this abort also happen if an external HSE oscillator is used?
