WebNov 26, 2024 · Here, TIMER_FREQUENCY (1 Hz) is the desired timer update frequency. You can see that this makes sense by thinking about the calculation for a couple of indicative frequencies. For a frequency of 1 Hz, with a 27 MHz input clock and a prescaler value of 27, we have that timer_reload = 1,000,000, i.e. we count up 1,000,000 pulses of … WebOÐcÉb·þV \jƒ ‰ê~ í Ñ‘ Z Ξ\Scƒ ˆl,twZ ½eöeè– '\hgÅk _s‚ ]\q ] Rà_f_ í ³\›l ÜY Nés Ngwm—g _[Ü€:_ Xo‡eïQ ûNÌS ^ ˆl„U‡e ½e ‚ýl ‹[8l \ ‹s`‰Š ‹stQ R 4T¾ öS ^PN öS×_im _~ ‡[ _è–tf hT)Yim ^ ZípÔkäS=N·íp T¦žÐc ‹„sO#k †š )YLˆ ÜYÇR NgÅ~í‹ Ng€sO ÌQ V š Xo f m_ z Y[_l Z Y[_[ïg Y[‹s° ¢ P[Ò[ _‡eeh Ñ ïQËe ...
STM32 DMAMUX: the DMA request router - Application note
WebDirect memory access (DMA) is used in order to provide high-speed data transfer between peripherals and memory as well as memory to memory. Data can be quickly moved by DMA without any CPU actions. This keeps CPU resources free for other operations. The two DMA controllers have 12 channels in total (7 for DMA1 and 5 for DMA2), each dedicated to ...
