Hello,I have a issue with my STM32U5G9. It does not go into standby or shutdown mode. I want to achieve a wake-up by the power button of my device. The powerbutton is connected to PWR_WKUP6 (pin PB5). The button has a 100k pull-up. I verified the vol...
We are facing an intermittent EWGF (Error Warning Flag) issue during CAN communication at 1 Mbps on multiple STM32 MCUs. The same hardware and software setup works reliably at 500 kbps without any CAN warnings.MCUs UsedSTM32L443VCT6STM32L443CCT6STM32...
My original aim was to prove to myself that I was able to measure execution time with cycle accuracy. In order to do that, I have 9 'test_dwt' functions, they all have same code except number of nop between 2 reads of DWT.That gives unexpected result...
I'm using the LCD of the STM32U073K8, but the program failed to initialize the LCD. After checking, I found that the STM32U073K8 doesn't have the VLCD pin. Is the STM32U073K8 not compatible with the LCD peripheral? Or are there other settings?
I work on a pedometer project, which uses built-in accelerometer and an LCD screen (ILI9341). The screen code works fine, but I struggle to get the pedometer part to work. I suspect there might something wrong with how I initialized the accelerometer...
Hello ST Community,I am working on an industrial combo vending machine controller system and would like to request a design review / best-practice feedback for an architecture based on STM32H563ZIT6.System OverviewMCU: STM32H563ZIT6 @ 200 MHzOperatio...
Hello ST Community,I am working on an OTA firmware update implementation on STM32L496, and I am facing an issue related to dual-bank internal flash usage when the firmware size exceeds 512 KB.I would like to explain my setup and the problem in a simp...
Environment: STM32L4 + 32.768K LSEFunction: Wake up and work once every hour, then enter stop2 mode. During the one-hour sleep, wake up every ten minutes to feed the external watchdog.Problem: The device resets directly when waking up every ten minut...
HelloIs there a book about Cortex M7 like Yiu J. The Definitive Guide to ARM Cortex M3 and Cortex M4 Processors ?
the best I achieve so far using DWT as well as PMU is 'few cycles' accuracy. My question is, how I measure execution time such that I get 1 cycle difference when I insert a nop in the measured code ? (assuming interrupts and caches are disabled).Both...
