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 04:24I was interested in trying Espruino software on an STM32F4 and downloaded ST-Link.Unfortunately, when I try to run STM32 ST-Link Utility.exe I get a dialog''This application was unable to start correctly ()xc000007...
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 October 28, 2013 at 03:58Why synchronize TIM15 with TIM16? CPU: STM32F100C8T6 From datasheet (Doc ID 16455 Rev 3) ''TIM15 can be synchronized with TIM16 and TIM17.'' From STM32F10xxx Reference manual: ''14.5.3 TIM15 slave mode control regi...
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 14:31Hello everyone ,In Discovery board , by default 2 DAC channel activated . I want to activate only one .Is there anyway to configure this ? I am trying to modify DAC_Init ()..but :( ..... #dac-stm32f4-discovery-b...
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...
