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…
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…
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…
Hi everyone!!! i'm new to STM32f4. i was wondering if this microcontroller can amplify an input analog signal through audio jack i.e an audio signal and produce amplified voltage at any gpio pin...
Hello,
I am trying to implement a 60kHz bandpass filter in a STM32F407 microcontroller with the help of the CMSIS DSP Library, and unfortunately I am having a bit of trouble... I am wondering if someone here might know what I might be doing wrong. I've…
Greetings Community !
Im currently working on my custom real time kernel project (STM32F7). It was really in mature stage of developement, when i figured that its not compleately ISR safe, gets stucked sometimes, corrupts some data etc. Im rebuilding…
Hi I'm learning cortex m4 debug feature,
I'm using stm32f407 discovery with openocd in ubuntu
I'm trying to understad breakpoint feature,
I can set breakpoint address in openocd and chip will stop when pc run to that address
like main function…
Hello everyone. I write FFT, it's ran! But it run very slow speed, I try on STM32F103C8T6 72MHz and used timer to measure time, the result about 360ms and I can't run another program. Somebody help me please! Thank all!
My code here: the DFT http…
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…
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?

Hi Friends ,
I need to fix this problem and I've read something about gcc but I didnt understand how can I do it.
[cc] C:\Users\Emrah\Desktop\imu_STM32F407\imu\Src/main.c:39: undefined reference to `atan2'
[cc] collect2.exe: error: ld returned…
I have bought this Cortex M3 board. Now I want to program it through jtag.
So I bought this wire. By using the USB to serial interface of my linux machine, I want to program the board.
I went to read the data sheet of board here[1]. In section 2.3.29…
Hello everyone!
I want to buy STM32F103C8T6 and my os is Ubuntu and I don't want to use IDEs. I already found the developer's tools - GNU Arm Embedded Toolchain, but have the question - there is a suitable linux software to program ARM devices…
