Calculate ADC DMA Buffer Full Period
I'm trying to calculate the period of DMA ADC interrupt triggered when the destination buffer is completely full. As of my understanding the period is:T_dmaDone = [(T_sample + T_conv) * sampleCount * channelCount] / F_adcIn my case each rank is set t...
edge-blanking with 3-phase center-aligned PWM
Hello,Comparator in STM32G4 is very fast. some glitch which is detected by COMP (during commutation PWM).The overcurrent detection using internal comparator triggers below the theory (40A insteand 100A for example) I'm having trouble implementing the...
Resolved! Wake up vs Alert in RTC
Hi, could someone explain me what is the difference between wake up and alert in RTC?For example the UM1749 provides information about RTC Alarm functions (section 39.2.8) and wake-up functions (section 40.2.2)When should I use the wake-up and when t...

Connecting to STM32 on NUCLEO-G474RE over USB
I'm just getting started with the STM32, only got the NUCLEO-G474RE board yesterday.I need to communicate from a PC to the STM32 over USB. Am I correct in assuming that the CN1 USB connector is only available for ST-LINK, and I need to attach a seco...
STM32L4 STKERR in case custom bootloader and application starting at 0x08010000
Hello,I have created a bootloader application that jumps to main application at 0x08010000.It works fine, except when I run in debug mode. In this case, the first execution runs correctly. If I push stop and restart button the application goes to STK...
