Dear team,I am using a STM32G474 in my application. I've generated a PWM in the HRTIM TIMER E that is active low (necessary for the requirements of the modulation). I want to insert a dead band between this signal and its complementary (Output 2). Th...
Hello, ST community, I am having trouble installing a Batch file from the STSW-LINK009 Software ZIP file. I am on a Macbook Pro M2, running Parallels Windows 11. When I try to download the "stlink_winusb_install" batch file I get a pop-up saying that...
Hi,I am working with stm32g491re.I am communicating with TCA9537(Ioexpander) from stm32 through I2C. It will control a realy. For my product EFT(Electrical Fast Transient) testing, After starting EFT teat relay getting turned off and not recovering....
Hello, I'm working on STM32H743BIT6, It is in production phase. During flashing the software, it is failed to configure LSE crystal with internal RTC enabled. out of 50 boards 2 board got failed.During debug it is observed that the RTC clock configur...
@Erwan SZYMANSKI I am trying to establish SPI communication between two STM boards: the Nucleo G431RB as the master and the STM32MP157F-DK2 as the slave. I followed the instructions provided in the Getting Started with SPI guide and configured the se...
Hello everyone! I want to use some MOSFETS to individually power up/down sensors on a PCB. Here's the schematics : The MOSFET is a DMG1012T-7 (N-Channel) and here's it's datasheet : https://www.lcsc.com/datasheet/lcsc_datasheet_1809050424_Diodes-Inc...
I'm working on a project using the STM32H563RIT6 microcontroller where I need to receive data over UART using DMA with idle line detection. The data is sent from a Python script using 'pyserial'. My setup is as follows: typedef enum{ IDLE, SE...
I am trying to use ADC with DMA on STM32H743XI. I set up ADC1 IN7~IN9 and use three uint16_t to store their converted values. I use DMA2 Stream 0 to transfer data. CPU ICache and DCache as well as MPU are disabled. ADC Clock Mux is set to PLL2P 50MHz...
Dear, I am trying to run the CAN Communication in STM32F407 discovery board, In CAN_INIT I have made controller state to Ready after that I have changed the controller state from ready to LISTENING in CAN_START function, but when I am trying to exe...
Hello,I tried to set a capture/compare register to a value beyond that of the auto-reload register, and the timer I used (TIM8) behaved as if the value had not been written. Reading back gives the expected value though. I haven't dug more but I'm cur...
