I have to connect my STM32H7 board to a network with unkown parameters. Is it possible to use the FDCAN Clock calibration Unit (CCU) to do an automatic baud rate detection of the arbitration phase.
I'm trying to use the frequency measurement with NUCLEO-U575ZI-Q. As per suggested, the max allowed frequency of SYSCLK is 160 MHz which I use. I'm configuring TIM2 Channel 1 in direct input capture mode. I use 0 as the prescaler and the max value fo...
Hello,I need to know what the minimum required current is to drive a pin as input for the STM32G0-series. I've gone through the datasheet but cannot find anything concluding for me. Could someone tell me?The reason is that I use a power switch to mak...
Hi,I would like to measure the times and pulse lengths of an external signal from a GPIO. For this I wanted to use a DMA trigger (which writes the time points from the Tim to the memory).Here are 2 questions:1. where can I find a document that states...
Hello all,I am trying to implement an external loader for my board. Which uses a W25M02GV (QSPI NAND FLASH)I am following the https://github.com/STMicroelectronics/stm32-external-loaderI am trying to configure an STM32L4 to use this memory in mapped-...
Hi there,I have a board with STM32F429BI and DM9000(connected to MCU by FMC).I enabled and config the FMC in cubeMx, after that, the LWIP is still gray(can't enable it).Does that mean only when the ETH is configured then the LWIP is useful?If I want ...
I'm working with an STM32G474 microcontroller and need guidance on how to write 32-bit data to flash memory. Could someone provide me with a proper procedure or example code that demonstrates how to accomplish this task efficiently and correctly? Any...
I have read most of the replies to posts that had the same problem that I am having with HAL_Delay() not working. None of the solutions that I tried worked. It is apparent that the interrupt handler is never getting executed so any attempt to use HA...
The STM32G4 I'm using supports up to 8 hardware USB endpoints. I'd like to it to enumerate as a composite device with 3 CDC-ACM channels (doing so would greatly simplify the host software). Since each CDC-ACM class device requires 3 endpoints one eac...
Hi ,While exploring flashloader macro using IAR IDE to update Option bytes , I programmed FLASH_OPTR register with Readout Protection level 1.Since then I am not able to communicate to device using STLink and following is the errorIs there anyway I ...
