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, ADC_CR_ADCALLIN is described as "rw" . The procedure given in RM0456: 33.4.8 Extended calibration mode does not explicit recommend to reset ADC_CR_ADCALLIN after the procedure. I think it is helpfull to add in RM0456.
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?
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...
I have a custom PCB with an STM32H563VGT6 microcontroller and an external Winbond W25Q16JVUXIQ NOR flash memory connected to the octoSPI's (XSPI) upper four pins. The problem is I can only write data to the flash memory after an erase, if I reset my ...
