Posted on October 25, 2013 at 10:54Hi, I am working with STM32F401 discovery board. I set up the system_stm32f4xx.c file so that the system clock becomes 84MHz(I used Excel based stm32 clock generator tool to get PLL values). void Delay(uint32_t dl...
Posted on July 29, 2013 at 23:52What limitations are there within the PDM filter library? I'd like to be able to record with FS at 8KHz...the original project files show 32KHz spi configuration but FS at 16KHz and the low cutoff at 8KHz; if I want t...
Posted on October 27, 2013 at 15:00Hello,I am compiling with the ARM GNU toolchain for the STM32F103 family, and want to adopt CMSIS as I believe that is will ease programming after I climb its learning curve.It appears that the STM32_USB-FS-Device_...
Posted on October 26, 2013 at 10:33Hi,Dear all, I am new to this series. Specially I am unable to find examples on it for this version and I have a limited time to implement input capture to measure frequency between 210KHz-510KHz.I am using Timer 1...
Posted on October 25, 2013 at 18:34Hi, I am working on the DFU recently.1. I modified a STM32L Discovery board with STM32L152RBT6 to have USB capaility. http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/PF2509902. Then I loaded the ''Device_Fir...
Posted on August 27, 2011 at 08:10I have been reading and learning on this forum for awhile as i worked through my first decent size project with the STM32. I thought it was about time i posted up here and contributed some code :) I have just got a ...
Posted on October 23, 2013 at 17:22Hi all I've a little problem. I use the USB driver from st to communicate with my STM32F4-Discovery. This works realy good. But I've would make a streaming protocol with a camera sensor. For this I have to use the ...
Posted on October 25, 2013 at 16:06Hello, i'm trying to use the SPI Communication. I have followed the instruction from the reference manual. But there is still a problem to write the tx data. When i use the debug mode the SPI1->DR will not be writt...
Posted on October 01, 2013 at 09:58Hello, I am trying to read data from USART using DMA. Receive buffer (DMA_BufferSize) in my code is 4 bytes, but even when 1 byte of data received, MCU is interrupted with Transfer Complete flag (DMA_IT_TCIF1). Giv...
Posted on October 24, 2013 at 21:18Hello, I am new to developing on an STM32L. I'm using IAR Workbench to compile for it using FreeRTOS. I don't seem to be able to be able to get it running using any of the C/C++ functions. I can build a simple task...
