How can I generate variable phase-shifting 4 PWM signal reference to one another in STM32H7432ZIT6U

Hello i want to to generate variable phase shifting PWM

STM I2C-3 not generating a clock and data signal on one of the I2Cs.

I am running an STM32L476RG at 1.8V and have noticed that I2C-3 does not generate a clock or data signal. I have tried isolating the MCU from the rest of the circuit and found that there is still no signal at the MCU pins, so i know the circuit is no...

QSPI peripheral state remains busy when using DMA

Hi,I'm trying to use QSPI to interface with a flash memory chip (GD25Q16). I can read and write to memory and status registers using blocking code, but I'd like to use DMA to decrease the CPU load. However, the QSPI handle's State gets stuck in HAL_Q...

Resolved! B-L475E-IOT01A Virtual Com Port (VCP) USART1 Not Working Using Mac OS X 10.13 and USB-C

I'm using STM32CubeIDE/MX to program and debug a simple demonstration of UART on the B-L475E-IOT01A development board (with integrated STM32L475VG). The code is straightforward (and autogenerated, apart from the hello world message).Probing the pins ...

STM32L011 + systick + WFI problem

Hello, my STM32L011's core is running at 32 MHz. I use systick for 1 ms interrupt. However, if i try to use the WFI inside my while loop in my delay function, the timebase changes from 1 ms to 6.28 ms. Any help is appreciated!#include "user_systick.h...

[Coverting Arduini Code -> CubeIDE Code (c) ] HAL_SPI-Transmit function

Hey Guys, iam trying to convert Arduino Code to my C Project in CubeIDE..I have some troubles(=warnings and iam unsure) with the SPI Trasmit functions.Could you tell me if my code does the same as the Arduino Code?ARDUINO : ******************* void ...

Resolved! In STM32F7508-DK board , If all flash of 64 KB is occupied, Can we use QSPI Flash ? If yes then what is exact procedure ? Is there any drawback ?

We are Planning to Use STM32F7508-DK board for our Application. As I go through Datasheet of it. It is mention that 64 KB for internal flash. But I am very sure that my application required more than 64 KB. Question : Can we use QSPI Flash in case ...

i have ported the Emulated UART Code for STM32L431CC from the STM32F401RE.

peripheral settings done properly.STM32F401RE -- has settings DMA2 & GPIOA (PIN_10 & PIN_11).STM32L431CC -- But i have configured -- DMA1 & GPIOB(PIN_10, PIN_11).Data Transmission & Reception not happening. any suggestions .

STM32H7A3 - problems with SDcard

I'm trying to use a SDcard on a STM32H7A3ZI and hitting a roadblock. Everything in the initialisation wotks until the SD_SendSDStatus function in stm32h7xx_hal_sd.c. This fails as it never sees __HAL_SD_GET_FLAG(hsd, SDMMC_FLAG_RXFIFOHF) and always ...
