STM32L4 ADC Oversampling period
I am planning to use STM32L4 hardware oversampling by a factor of 2. With the current setup (without oversampling), I am triggering ADC capture and conversion using Timer update event. The timer update event is generated at 10kHz and so the ADC is s...
Resolved! STM32L432 Nucleo-32 External Power
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...
How do prevent RTC time from resetting when jumping to application? with IAP (In Application Programming)
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...
Problematic 'L071 TIM3_OR3 bitfield description
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...
Resolved! Cycle Counter vs SLEEP - code correct?
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...
STM32 DFSDM, cannot get the right resolution
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...

Resolved! Value of register VTOR at reset on STM32H753
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...
Flash erase is not working properly on STM32L4A6RGT6
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...
