Hi,I am using stm32f779 RTC upto subseconds granularity that is using SSR register value for giving upto milliseconds level of time output .The scenario is such that there is external time source ( network clock) to which I synchronise RTC by updat...
Hello,I have written these codes for transmitting an array to USART.1)The Message[21] Array fills up every 200us. It sets Flag=1 when data is ready.2) If the user makes the PB11 pin low it starts DMA section to transmit the data.(All data will transm...
I can't seem to find this in the datasheet or reference manual. The GPIO OSPEED register is documented as 00: Low speed, 01: Medium speed, 10: High speed, 11: Very high speed. But what are the actual frequencies? I can't seem to locate the informatio...
Hellofor my application I use STM32L0, and I want to retrieve the exact date without changing it every time I turn off the power. Is there a timer that was triggered on the production day of the STM MCU that will allow us to retrieve the date?
Hello everyone,I read many of the posts on the forum and couldn't find an answer to this question: is there any way to start timers in one pulse mode other than through an external stimulus? that is, only through software? How could it be done?I am l...
RM0351 and RM0392 (and maybe others, haven't checked them all) contain this in the System clock (SYSCLK) selection sectionStatus bits in the Internal clock sources calibration register (RCC_ICSCR) indicate which clock(s) is (are) ready and which cloc...
Hi -I have a STM32429I-EVAL board. Before I start mucking about with it, I would like the original firmware file (bin or hex file). I may want to go back to the original demo fw at some point. Here is the system info:Demo Rev: 1.4.5Board: STM324x...
Hi folksI'd like to ask about STM32H750B-DK. This a demo board based on the Value Line STM32H75O with 128kB Flash and 1 MB RAMI saw its demo movie on the YouTube and would like to understand whether it runs from the Flash or RAM? Or in other word...
Hi everyone!I'm pretty new with STM32 microcontroller and STM environment. Now I'm playing with a Nucleo-H745ZI board and developing using STM32CubeIDE. This board is equipped with the st-link V3. It should be able to use both SWO and JTAG interface ...
