STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I'm using the STM32L152. At certain points in my code I go into STOP mode. It seems to come out immediately. I'm not sure what interrupt or event is causing this. Is there any indication somewhere what event caused the processor to change modes? Than...
Hello ,I have recently bought a Nucleo-144 with an STM32F303ZE . Ive been testing out basic programmes including ADCs and I am new to STM32 and embedded in general .Problem:I need to sample 4 channel input Intermediate Frequency(2MHz signal , and i ...
Hello, I'm trying to wake up from stop 1 with the alarm A, and I was wondering if someone can help me with this. Here is my code (I'm using HAL libraries first, the "easy" way base on the example ST gives: PWR/STOP1_RTC):...int main(void){ GPIO_Ini...
This part is mentioned in several places: AN4938, Rev 3, http://www.openstm32.org/tiki-view_forum_thread.php?forumId=2&threadId=7657&comzone=show#threadId7657 but I can't find specifics on it.
HI, ALL!RTEMS is a RTOS. I want to make it enter stop mode like below codeif(PWR_STOPEntry == PWR_STOPEntry_WFI) { /* Request Wait For Interrupt */ __WFI(); } else { /* Request Wait For Event */ __WFE(); }so i have to call __wfi like under ...
When working with a STM32F030C8T6 board, communicating with another board through serial comms (115200bps), I suddenly started to get erroneous characters once in a while, when the remote board were sending data at the same time.It's a block protocol...
Hello,This question is just to make sure the STM32F4 DISCOVERY extension board is compatible/works with STM32 F411E DISCOVERY board. (We know it is compatible with STM32F4 DISCOVERY board). As per online, the extension board mentioned as applicable f...
I tried to evaluate a Nucleo STM32H743ZI board a few months ago but the serial wire tracing wasn't possible with the HAL drivers.https://community.st.com/s/question/0D50X00009XkhURSAZ/stm32h7-swo-printf-not-workingIs this bug solved by the way? Is an...
