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…
Hi. I have an INVPC exception that I am trying to debug on a Cortex M4 STM32. The stack contains the following values:

The PC and LR both point…
Hi everyone!
i'm trying to add CMSIS-RTX5 in my project.
Without RTX5 the code run correctly.
Adding RTX5 the following error appears:
.\stm32_base.axf: Error: L6200E: Symbol PendSV_Handler multiply defined (by irq_cm4f.o and stm32l4xx_it.o).
.\stm32_base…
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…
I just downloaded the SVD files for ST and after parsing them into our debugger I find there are a couple of errors. I have snipped the three entries that appear incorrect.
If we assume we need two rows of data, one for STM32F0x2 and one for STM32F0x8…
Hello
Sorry if my question is repetitive and boring but I'm here after 4 hours searching!!
I have an STM32f4-discovery board and liked to programming it with CMSIS library! but there are many tutorials on web in text and video that they are ambiguous…
I use CMSIS/DSP library in an audio application. I have issues with the conversions 16 bits PCM (=>) Q15 => float => Q15 (=>) 16 bits PCM (in fact no
real conversion between 16 bits PCM and Q15, as I understand that it is the same thing)
I use…
Dear All,
I am using STM32 device with MDK Keil 5.06 version.
My project was developed in Coocox environment.
Right at the moment, coocox is inactive in Forum.
I have make a new project on MDK Keil and start to adding all the related HAL driver and other…
Hi All;
I have some questions about correct use of the CMSIS DSP library call arm_fir_32. First, I'll provide some background about what I am doing and what the setup is.
I have a STM32F4 Discovery board, using IAR EWARM for programming. Just for…
Hi, experts.
I'm recently working on CMSIS RTOS with MDK-ARM V5.1, on STM32F103 MCU.
I'd like to know about using IRQ of DMA on RTE(Run Time Environment).
My application uses following functions.
- UART with "UART API" on RTE(Run Time Environment…
