Hey guys, I have a question regarding the STM32H745 (Nucleo-144 board). I wanna output data on the DAC using the DMA, but it is not working. Iam using the Cortex-M7 core, the DAC is triggered by Timer 8 trigger out event. Any hints? Greets

during the initilaztion code , my port pins are misbehaving. how to over these problem?

EMMC64G-W525-X01U is not working with STM32F429ZI.

I am reading Data from 8 ADC- ADS8688 and writing to EMMC64G-W525-X01U with Queue of 100 and Block 512 at 1000 sample/sec. I use below function for data writing and API file is attached below.HAL_StatusTypeDef HAL_MMC_WriteBlocks(MMC_HandleTypeDef *h...

Enable a UART loopback connection on the development board STM32L476, to send "hello world" from UART 1 peripheral to UART 2 peripheral of the same microcontroller. I can not configure 2nd UART in Async mode. Can anyone guide me on it?

STM32F417___WRITING DATA THROUGH I2C3 CAUSE EXTI9_5_IRQHandler TRIGGER

1) I have configured PG8 gpio as external interrupt mode.2) When i am writing data using I2C3 , EXTI9_5_IRQ Handler is getting trigger,but their is no activity in PG8 pin. What is the reason for this problem.I2C3 GPIOs. PC9 -> SDA PA8 -> SCL
