STM32 timer sets CC interrupt flags on overflow

Posted on January 06, 2012 at 23:59I found that when output compare registers are loaded with a value that is more than ARR, then on overflow the timer automatically sets compare match interrupt flags.  Has anyone seen it? #stm32-timer-inerrupt

STM32F4: TIM Triggered SPI Transmit

Posted on May 13, 2013 at 23:27 Hi, I am trying to interface the STM32F4Discovery board with an external A/D-converter. The A/D generates a GPIO interrupt as soon as the data is sampled and ready to be retrieved. After that 3 * 8 bytes h...

Starting two timers synchronous

Posted on January 12, 2012 at 21:59Hello everybody! In my program I have to start two timers exactly at the same time. In my current code I start them behind one another (just one line of code each) but unfortunately the error with this method is to...

Not desidered auto-reload TIM2

Posted on June 06, 2013 at 00:02Hi,i'm angry with this simple code.I need that the timer2 goes from TIM2_ARR to zero and stay zero until a Update EVent is manually generated (with UG from TIM2_EGR of course).But unfortunately TIM2 seems to reset at ...
