Posted on October 28, 2013 at 14:02Using an STM32F407I am using a timer to capture the time between two TRGI events. It is set to reset every trigger in event. In my current code, the ISR for the TRGI event reads the CNT value to determine this valu...
Posted on October 28, 2013 at 15:54Hi everyone,I have to handle strings in my code and I don't know how to use this type of data. I assume that it comes with the compiler I'm using (gcc arm-none-eabi). I found and declared 'string.h' at the begining...
Posted on October 26, 2013 at 15:11Hi, the STM32L1 have an interesting new feature which is named ''Routing interface''. Has anybody used this already, or is there any application note describing its use in more detail than the Reference Manual?
Posted on October 28, 2013 at 04:14Hi everybody,I'm working with OV2640 and i've problem with brightness. I use TFT LCD to display, use config from STM32F4xx_DSP_StdPeriph_Lib ( dcmi_ov2640.c). DMA and DCMI working fine but the image i receive too d...
Posted on October 28, 2013 at 10:53I work with STM32F103RBT6. In stm32f10x.h i set #define STM32F10X_MD, it leads us to : #define SYSCLK_FREQ_72MHz 72000000 in system_stm32f10x.h. So SystemInit() function should go to SetSysClockTo72(). However on ...
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...
