STM32H503 code execution performance issue

Hellofor some specific usage I am evaluating possibilities of using CM33 with HCLK 250MHz for maximum code execution performance. To do so I have crafted procedure in assembler and calculated the cycles using ARM reference manual. The code is doing o...

ULPEN - ST please unify nomenclature

In 'G0B1, 'G071 and 'L412 Datasheets, ULPEN is mentioned several times (namely 3 times).It probably corresponds to PWR_CR3.ENB_ULP in case of 'G0x and PWR_CR3.ENULP in case of 'L412/'L422.I did not check if this propagates to newer STM32, too.ST, can...

Square wave FSK issue using PWM ouput

Hi All,I am trying to impliment a frequency shift keying (FSK) routine to represent a each bit of a byte as FSK.My routine is kind of working (see the IRQ for TIM3 below). My FSK is :Bit 0 & Start : 3600Hz Bit 1 & Stop : 1200HzThis ensures that timin...
