I just find my HAL_UART_Transmit() function cost 15ms. why does it cost so much time?The UART speed is 19200, and I use GPIO set and reset function to check the time cost.Total data length of send buffer is 29 bytes. and I use a 15ms polling loop to ...
I am using TIMER 14 for counting test durations in my projects however I am lagging off aroumd 5 mins per week.How can i implement the same with RTC counter?
Problem Statement: Amplifying Low-Amplitude Audio Signal on STM32 Nucleo64 BoardHello STM community! I'm new here and seeking some guidance. I'm working on a project using the STM32 Nucleo64 board to create an announcement maker. My setup involves us...
Hi all, I tried to communicate(private) with my I3C slave device by using STM32H503RB board (as a controller). Here's the code from "Introduction to I3C for STM32 MCUs - Application note Chapter 9.8 Private read" uint8_t aTxBuffer[1] = {0x0F}; u...
Hi, I am working with STM32H503RB.I'm currently testing the function of "I3C_Controller_ENTDAA_IT" from the example code.Capture1 is the result of "I3C_RSTDAA_THEN_ENTDAA"The expected behavior of Capture1 should be 7E06 then 7E07.Why would 7E02 occur...
Hello,I've a project with the STM32G030F6 which the application use in 90% of time the low power sleep mode. In the reference manual page 95 is written that can debug:But in the register DBGMCU_CR dosn't exists a flag for the low power sleep mode. On...
I'm using a STM32H753 with external RAM. We were using it for LCD framebuffer. Now we are trying to migrate the stack and heap to the external RAM, when we run the code, getting hardfault on lines where std::array is declared. Any idea on how to debu...
I have an issue when changing the option bit of STM32H742 to change the RDP level to 1.I read out option bit from register FLASH->OPTSR_CUR, change the RDP bits to eg 0xBB, write the result to FLASH->OPTSR_PRG and then set bit FLASH_OPTCR_OPTSTART in...
I have recently upgraded CUBEIDE to v1.15.1I tried to add a example project to my workspace and it states Required Software PackageWhen I click next and finish, I get the errorI have checked for updates etc and tried to download manually using Embedd...
Hi all, I've been working on reducing the power consumption of a project I'm working on using the STM32G431.Stop modes are not an option on this chip since I need to keep some peripherals active, but I've beenable to reduce the needed system clock to...
