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 03, 2012 at 16:47Hi, I need to force a reset on the stm32L32152 after the stvp programming session. On the st site,there is the stvp source code and api example. I saw the list of exported functions that may be called in EPRCORExx.DLL...
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...
Posted on July 11, 2012 at 09:14Hello everybody, I'm using the STM3210E Eval board with STM32103ZGT6 �C. I'm currently doing any tests in order to determine the quickest way of data transfer between external SRAM/NAND or external SRAM/SD Card. I wan...
Posted on July 11, 2012 at 09:25Hi, I trried to understand how to calculate pwm output from example that comes with Stm32f4-Discovery-FW1.1.0. The file is in Project > Peripheral_Examples > TIM_PWM_Output > main.cThis is the most confusing part in...
