Posted on July 11, 2012 at 14:52hi alli need to know that is DMA uses the SRAM as the DMA buffer??????if yes then my MCUstm32F407 got 112Kb and 16Kb of SRAM.and DMA max buffer size is 64kb, in the case DMA is using half of my SRAM,is there a possibi...
Posted on July 11, 2012 at 13:55Hello ,I am new to STM32. I am reading data from USART using DMA. I dont know how to directly access data from DMA memory after transfer complete interrupt.
Posted on July 11, 2012 at 16:59Hello, in the Document RM0008 (datasheet of the STM32F10xx Family) on Page 510 is the FSMC access described with the external WAIT Signal. It works well for my application now, but i have some problems by understandi...
Posted on July 11, 2012 at 16:36Hi all, I have a simple routine called in TIMER_IRQ event that set GPIO and than set a DAC on SPI BUS. This routine must be quick as possible. Regarding the GPIO setting there is no particular problem, while SPI has s...
Posted on July 11, 2012 at 15:30Hello, I am using an STM32F100RB and want to use the clock output MCO on GPIO PA8, so i have to set the GPIO to 'alternate function push-pull'. But I also want to use USART1 with TX on GPIO PA9 and RX on GPIO PA10. So...
Posted on July 10, 2012 at 20:12Hello, I my application, I need to control multiple ( >3) half bridges and measure current(s) synchronously as well. Question 1: Is it possible to synchronize the counters of Timer 1 and Timer 8 (and others?) so that ...

Posted on July 09, 2012 at 21:06I have a problem. I connected to spi stm32f103 and stm32f405. The data is transmitted, but only 8 bits. Initialization codes below. What is the problem?Code for master (stm32f103):SPI_InitStructure.SPI_Direction = SPI...
Posted on June 10, 2012 at 16:47There is a missing table in RM0090 para: 14.4.3 TIMx slave mode control register (TIMx_SMCR), Table 60: TIMx internal trigger connection on page 395 I am trying to use TIM1 timer as a prescaler to TIM2 and TIM5 tim...
Posted on June 14, 2012 at 15:17Hi,I'm using the STM discovery board and IAR (IAR-STM32F407ZG-SK) board to write the preliminary FW routine for my project. (the IDE is IAR)The problem start when I try to use the DSP library function in my programs.T...
