Posted on May 15, 2014 at 17:06 Hi, I am using uvision4 with stm32f1xx to meansure frequency counting the time of the falling edge pulse. I need a high precision to meansure frequency from 0Hz to 240Hz. The first thing that I do was to set the pre...
Posted on May 23, 2014 at 20:15 whenever i perform the dma transfer, I always get a transfer error on the write to TIM1->BDTR. If I write to a different peripheral register, such as TIM3->ARR, it succeeds. Any thoughts? TIM_TimeBaseIni...
Posted on May 23, 2014 at 16:07One thing I have not been able to find in the datasheet: if the FSMC is being used to access 16-bit memory, what does A0 do? I'm a bit confused about this. If BCR.MWID is 00 => 8-bit data width, you have to address ind...
Posted on May 05, 2014 at 22:36Hello Everybody, in the process of compiling some of the Examples for the STM32F429DISCO on a linux machine I noticed that Include paths are specified using backslashes instead of slashes. Obviously, backslashes only w...
Posted on May 22, 2014 at 04:27hi, I found there is a problem with the bit mask for the RCC AHBRSTR Register in the stm32f30x.h. * @file stm32f30x.h * @author MCD Application Team * @version V1.0.0 * @date 04-September-2012 #define ...
Posted on May 21, 2014 at 14:09Is below is right way to send STM32F205RBT6 in sleep mode:I have to do some task, then send MCU in sleep mode for 1 sec & then again execute those tasks.main(){ while(1) { // do some task configure_timer_1_sec(); //c...
Posted on April 30, 2014 at 22:12I'm trying to setup my project on STM32Cube just like the BSP provided with the STM32F439 in the firmware examples. Looking at stm324x9i_eval_sdram.c I see that SDRAM is configured on Bank1 with 11 address bits and (...
Posted on May 21, 2014 at 15:46Hi,I use STM32F427 chip. In my application, I am generating a 25.6 kHz signal using an external signal with 9.984 MHz. In order to do so, the calculation for timer period should be as follows; (9.984MHz / 25.6kHz) - 1 ...
