window watchdog can not generate ewi interrupt

I configured window watchdog with ewi interrupt enabled, and enabled isr for WWDG_IRQn too, But it can not generate interrupt before reset the core. And there is no HAL_WWDG_Start_IT() function in stm32h7xx_hal_wwdg.c.

What maximum Baud rate STM32G473 can support?

Actually, i don't get any max value for UART baud rate in datasheet as well as in reference manual.

STM32F103R8 - Random Hard Faults on simple(?) project

Full disclosure. I'm new to STM32 and i'm porting from Arduino based 8 bit code to run on an STM32F103R8T6. This is on a manufactured / assembled PCB with supposedly genuine micro and not a random ebay blue pill board.While debugging I'm getting rand...

Hello, I would like to find the source codes for the STEVAL-IME011V2. I would like to make some modifications in order to test the STHV748 for my application.Cordially

Not understanding PDM 2 PCM

Hello,I am trying to use the PDM 2 PCM library to read in a MEMS microphone and am having some difficulty understanding the code below. If I wanted simply output the converted PCM data over a UART, what would need to be done to do this?My assumption...

Can you please help me what is MDMA, BDMA? What is the difference between DMA and them? Can you suggest me a good explanation document, please?

STM32F413 CAN BUS Problem

Hi, guys!I'm using a board developed in my company that uses a STM32F413VGT3. It has a MCP2551 and I have to use CAN BUS to comunicate.The problem is that we're using PD0 and PD1 as CAN1_RX and CAN1_TX, because PA12 is used to USART1_RTS. I'm able to...

I need to write a multiple (6 at least) cdc devices with hardware flow control within one STM32F403. The data would be processed, then sent modified via one UART. Examples I found are old and hard to follow for new CubeMx generated code.

Is there a way to set timer CH1 pin (PA5) to LOW from code?

I have configured TIM2 to set CH1 to Force Active if x Pulses are reached. That's working fine.Is there are a way to set it to LOW again from code (main loop)?This seems not to work:HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_RESET);
