Posted on June 09, 2016 at 20:36 Hi all, I'm trying to setup a very simple Memory to Memory DMA transfer. DMA status registers report that the transfer completes OK, but the memory contents is not transferred. Can anyone see why...
Posted on June 12, 2016 at 08:51Hi!Im trying to use two EXTI on PE2 and PE3 pins simultaneously. Two push bottons are connected to these two pins with a pull-up resistor and a capacitor filter prohibitting debounce phenomenon. As shown in the code b...
Posted on June 08, 2016 at 05:37By the DM00032020 Reference Manual, when TIM2 is used as slave, it's trigger source can be IRT0 from TIM1, ITR1 from TIM8, ITR2 from TIM3, IRT3 from TIM4. But now, when choose trigger source ITR1 in the 'pinout' card....
