Posted on November 30, 2017 at 21:45I have developed a program that runs on the STM32L432 Nucleo-32. When I write the program to the demo board using the USB everything works great. When I remove the USB cable and connect 5V/GND to the board, L2 goe...
I have a project with STM32L432KC, I have printed my custom board.I made the flash memory into 3 partitions: So far I've successfully create and running the code, but I found issue.Bootloader allow to receive new firmware (Application 1), synchronize...
This description is copy/paste from the description for 'L073/'L072 and the only relevant setting value was simply deleted - in the 'L071, there is no HSI48. In this way, this description makes no sense.That deciding to have separate RMs for the thre...
Heyho,I was just trying to check awake vs sleep in my H723 application (no OS), so I wanted to make sure that my code is okay.It's using the cycle counter to measure all the cycles when the CPU is NOT sleeping, then compares the cycle sum to the SysT...
Hello STM32-Community,I'm currently working witha PDM Microphone (SPH0641) and try to get it to work via DFSDM. I'm using the DFSDM tutorial vom STM32 to achieve the resolution required for my system.Currently I'm using:Filter Order : 3Fil...
Hello ST CommunityI encountered many problems when using DFSDM peripherals，Especially the trigger problem of injection modeThe STM32Cube H7 package which providing DFSDM example，Only refer a applicableation About AudioCan the ST official provide t...
The value of register VTOR at reset is "unknown" in the STM32H753 Programming Manual.I assume this is because it depends on the boot configuration of the product (boot pin and boot adress option byte) ?Is it correct to say that in the default boot co...
I'm trying to use flash erase to erase the address 0x08040000, its not erasing. I think I'm giving the values wrong for Bank and Pages.#include "main.h" #include "stdbool.h" typedef enum { NONE, PREPARATION, FLASH_ERASING, FLASH_ERASE_DONE, FLAS...
Using the PLL generated system clock frequency, it is possible to generate the same output frequency with many different pre-divider, Multiplier and post divider constant combinations. How can I determine combination is best for stability or lowest p...
To avoid the best accuracy when using the ADC it is advised to re-calibrate the ADC when environment temperature changes "too much"The ADC calibration can only be done when the ADC is disabled, so to re-calibrate the ADC has to be stopped, disabled, ...
