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...
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...
I am trying to get the CAN Loopback up and running on my STM32L431KCU (CAN1), I have tried to follow the: Guide to CAN (bxCAN/CAN2.0) configuration in Loop back mode on STM32 MCUs. But I am getting stuck in the "HAL_CAN_Start()" function where its wa...
Hello,here the exit of my (extended)initialization prodecure for ADC of STM32U535 running at 3.3v and 160 Mhz. Before setting ADC_CR_ADSTART, without the small delay or with the delay in line 14 and the limit for i smaller "6" like here "5" in the ...
