Dear all,

I am on the process of switching to GNU GCC for compiling an already working project. Most of the functionality has been tested. There is a failing test though: The USB VCP drivers do not seem to perform good.

The client side (PC-Windows) is…

I am getting data from a current sensor through the adc of stm32f407. I want to export that data to MATLAB at real time or at least at sampling frequency of 10 kHz. I tried STM TrueStudio but its sampling rate is only 1 kHz. So please let me know what…

Hi friends,
I am trying Can Protocol STM32F4 to STM32F4 ,I not sure about that I am doing right it.

If I use STM32F1 ,this device include just CAN master,so I mean if it is possible STM32F1 to STM32F1 because of both device include just master CAN.
STM32F4…

Hi,
I need help on STM32F4 micro controller. I need to interface USB POS printer with micro controller. I have done little bit working in USB HOST FS/HS Host programming. But i dont know how to write stack for USB host class for Barcode scanner and printer…

Hi Everyone @ARM Support Team!

   Working with a Board Support Package for the STM32H753I-EVAL, I found few issues -files nedded in the uVision Project.

   Now the critical file nedded is the RTE_Device.h.

Hi ! 

I'm looking for some documentation about startup file (startup_stm32l072xx.s, for arm cortex M0+), in order to understand how it's work and how can I modify it. 

For the moment I didn't find what I looking for, if somone have what I'm looking…

Hello

I m currently working on keil µvision 5 and a stm32L053R8 i have generate a code with stm32cubemx

Now i would like to change my MCU to program my prototype ( based on a STM32FO51K8T6) Did i have to re tapping my code ? or can i just import…

Hi guys,

I m currently using Keil µvision5 and i would like to know how can i put my headers in my .c ( with the little +)

best regards 

Hi guys,

I would like to know, How can import my code/ project / library ( this code is from a project on a STM32L053R8 ) to make it run on my STM32F051K6T8.

I have try to import my file.c but the header which correspond doesn't get imported

Hi, I am trying to learn programming on an arm micro processor. I have the evaluation boar STM32F303VCT but i am running into one major problem which is the tool chain.

1. Keil gives me an error if a start a new project and i cant even find m device in…

Hello, I am looking for information about programming an ARM M4 firmware to basically broadcast serial information to a bluegiga WF121-A wifi module. My device will receive 2 serial inputs and I want the serial input packets to be sniffed and broadcasted…

I have downloaded Keil 5.24a, and Arm cortex-M legacy support, when I want to create a new project, in micro selection step, in Software Packs there is no STM32F407VG micro, but there is STM32F407VGTx micro instead, and I don't know what is the difference…

Hi!

We're trying to use the CMSIS DSP library to filter a real-time signal using the CMSIS dsp fir function. We are using the STM32746ZG board. 

We've calculated the coefficients in C and they are correct according to MATLAB. We're feeding these into…

Hi friends,
I was trying download my codes on tm32f030 and everything was ok but suddenly Keil start to give "No Target Connected" I tried some ways but no solution.Any idea?

I m using STM HAL library and CubeMX,uVİsion V5.23,ST Link Utulity…

Hello,

I have a Nucleo-L476RG board and I'm trying to make a lowpass filter with the FIR function (using cmsis libraries) to filter the samples I get from the ADC in realtime.
Then I'd like to get the processed signal out through the DAC.
