And try also :Manual Loop unrolling (see for example or use if possible CMSIS DSP)Locate DATA in a SRAM and temporary var in DTCMRAMGive a look to FMAC/DMA of STM32U5 if DATA is not 32bits.
Hi, we need to convert one ADC sample HW triggered from random external event (0.1 Hz to 100Khz occurence).So stm32l4 errata workaround is not usuable for us.@Simon V., please can you confirm that stm32u575 with lqfp64 package don't exhibit the same ...
Avoid probing directly hse quartz.Try a very simple sw based on hsi and not hse to only toggle a gpio.Be sure of all powering, try to catch with scope very short undervoltage.Have a look to nrst pin. Try without any capacitor on this pin.What about o...
If you try Schottky diodes approch, GND and GND1 MUST be connected directly. Not through L3.If you try to keep LDO to feed Vdda with separate GND and GND1, you must verify that 24v gnd is GND1 and that vdd supply is referenced to GND. Keeping GND and...
Seems that vdda is not correctly decoupled. IC10 is on GND and not GND1.having a digital ground "separated" from analog ground is a good routing practice to avoid high speed return current from digital altering analog ground. But Agnd and Gnd MUST be...
