• HardFault on UART initialize

    Hi all!

    I'm facing a problem with my UART on a STM32F207IG under CMSIS.

    When I try to initialize the UART the processor disappears in the HardFault_Handler.

    I think the problem is somehow related to the clock settings which I left untouched until now…

  • error: Hard Fault Handler

    HI,currently i am working on project based on stm32f407 chip.my development work has been stopped since two days as i have stuck in hard fault handler. Please  guide me how to trace the fault ???i tried every possible way i could.but result in nothing…

  • IP Camera interface via STM32

    Hi all,

    I am looking for developing an IP camera based system based on STMicroelectronics STM32. The way it is supposed to work is:

    STM32F4 will have few IP cameras connected to it. It may have a web server running so it can be accessed from outside…

  • Please, recommend a book to learn coding in assembly

    Dear all,

    I really appreciate if someone recommend a book to learn coding in assembly. The target processor is STM32F0. Anyone there?

    I already checked those of Joseph Yiu. Actually, I need a book with clear examples. 

    Best regards!

    Hi friends ,I encountered a problem with serial terminal and ftdi.Let me explain.

    Stm32f103 is sending data to Ftdi and Ftdi is sending this data to serial terminal and I can see data, but I couldn't manage to send data to Ftdi from serial terminal.If…

  • Conflict, Register offset of GPIOx_BSRR of STM32F0x1/STM32F0x2/STM32F0x8

    Dear friends,

    Register offset of GPIOx_BSRR is shown as 0x18 (which looks to be true) in ST's Reference Manual (p163, en.DM00031936)  while it is shown as 0x1A in "stm32f072xb.h" header file. It seems to be a typo mistake. Any comment?
