Posted on October 11, 2011 at 12:34 Hi,I am using STM32F10xxx DSP library (not the CMSIS DSP) algorithm for calculating FFT of an input sequence.I want to know the order in which the input samples is expected by this algorithm and the order in which...
Posted on October 08, 2013 at 10:42Hi all,I�m starting to deal with STM32F30 discovery.I need confirmation about my assertion on default clock configuration for the stm32f3discovery_fw.In file system_stm32f30x.c the define PLL_SOURCE_HSE_BYPASS is u...
Posted on October 09, 2013 at 10:43Hi.I am designing a test board using STM32F0 series MCU.On the datasheet, it states I have to attach 3 bypass capacitors(2 x 0.1uF, 1 x 4.7 uF) per each VDD. Is it absolutely necessary?, What is the point of using...
Posted on October 08, 2013 at 23:35what is difference between two ''Partial Alternate Function mapping'' and ''Full Alternate Function mapping'' for @param in GPIO_PinRemapConfig() on stm32f10x_gpio.c driver?thank you #partial
Posted on October 07, 2013 at 08:59hello forum. I am new at arm so first I want to use the GPIO. I use stm3210c-eval. and this development board use stm32f107VC. I write code like this.#include ''stm32f10x.h''#include ''stm32_eval.h''#include <stdio...
Posted on October 08, 2013 at 18:29 Hi all, I use RTC_IT_ALR of STM32F102 to wake up from stop mode. In my IRQ Handler, I do this : RTC_SetAlarm(RTC_GetCounter()+ 10); and in main : while(1){ PWR_EnterSTOPMode(PWR_Regu...
Posted on September 16, 2013 at 22:20Hi all!I am wondering if anyone has tried jumping from flash code to an entire project in internal SRAM without resetting (so no memory remap / boot0/boot1 config is required). I am working on the STM32F417, and ...
Posted on May 13, 2013 at 19:46I'm using the STM32F407 in a new design and due to a conflict of peripheral pin assignments (Why isnt there more clk pin assignment flexibility?) I cannot use the JTDO pin of the device for JTAG. I think my only option...
Posted on October 05, 2013 at 16:11 Hello everybody, I try to use USART2 with DMA, but I have two problems. Now the code just sends back the received word. The memory is word based so I use the DMA controller packing/unpacking feature. My firs...
Posted on October 07, 2013 at 18:11 Hi I'm trying to write to the Flash ROM on my STM32F3 board (256k). Erasing a page works fine, but when I try to write a word (or half word), the MCU crashes. I'm doing what the standard peripheral l...
