Posted on June 08, 2012 at 17:42Hi,I am having some difficulty receiving SPI data correctly and I am hoping someone could help.I currently have two STM32L-Discovery boards connected via SPI with one acting as master and one as slave. My SPI transmis...
Posted on June 08, 2012 at 09:13Hello, I have a question about STM32F207 : Is it possible to connect an external SRAM + an external NAND flash on the same microcontroller through the FSMC controller ? What is the effect in this case in term of perfo...
Posted on June 08, 2012 at 11:03Hello, I'm having a strange issue ... when I upgrade from firmware X to firmware Y, the MCU is consumming more amps (board consumption from 50mA to 80mA), and generates more heat (from 42°C to 50°C). I checked a hun...
Posted on June 08, 2012 at 09:25Hello, I need some help about the ''spirious interrupts'' : I have a project with STM32F207 + external SRAM. Sometimes when I debug my software, a ''spurious interrupt'' occurs. What does it mean exactly ? I read on A...
Posted on April 03, 2012 at 19:57Hi all,I don't see this mentioned anywhere on the forum, but a new version of the STM32 USB library was released recently and it adds the long-awaited support for the STM32F4 family. I've tried it with the STM32F4-Di...
Posted on June 06, 2012 at 18:13Newbie here...I'd like to use one timer as a prescaler for another. Both these timers (combined) will act like a single 48-bit ''uptime'' value, used for timestamping events. The master timer will be driven off APBx.I...
Posted on June 05, 2012 at 16:28Hello All,I have been trying to write into the flash(certain user data), but when i debug it i see the values being written elsewhere in other locations and sometimes in the location i have specified.The function i ha...
Posted on June 03, 2012 at 18:14Hello, When I Enable DMA for Audio Transfer mode I never see any DMA events being triggered and demo does not work,as anyone have used this demo ?? Thanks gafsos
Posted on June 06, 2012 at 19:56hello forum , if I stop the timer --> TIM_Cmd(TIM5, DISABLE); do some job and restart the timer --> TIM_Cmd(TIM5, ENABLE); 1)does the PWM output change in between ? 2)does the counter start from zero or from the c...
Posted on June 04, 2012 at 18:02Hello, I select the ''BOR'' Level 2 with these lines after init: FLASH->OPTKEYR = 0x08192A3B; FLASH->OPTKEYR = 0x4C5D6E7F; while(FLASH->SR & FLASH_SR_BSY); FLASH->OPTCR = 0x0FFFAAE4; FLASH->OPTCR = 0x0FFFAAE6; ...
