Dear Sir/Madam,We used the STM32F072C8T6 processor in a project we carried out for the railway sector, and as stated in the link below, we currently need a SIL certificate to be able to submit it to the auditing firm.Link: https://www.st.com/resource...
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...
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...
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 ...
I want to design a baord with stm32h7b0zbt6 with extranal sdram chip W9825G6KH-6. I get PG15 with FMC_SDNCAS alt func in datasheet as below:But when I looked the PG15 alt func config I get as below info, I could not found an alternate function number...
Hello,Description: I am attempting to generate two simultaneous pulses of different lengths using a single timer (TIM4) and multiple channels.Current Implementation: I am currently using One-Pulse Mode (OPM). In my existing setup, the pulse starts at...
