I2C slave is not working in reading and writing

I am using STM32F7508-DK kit and Using I2C as a slave whereas ESP32 is a master, By using HAL_I2C_Slave_Receive_IT and HAL_I2C_Slave_Transmit_IT API I am able to do one way communication either read or write, but in my application I required read and...

Is there a difference in startup time between STM32F303 and STM32F407? I am experiencing relatively longer start up time for the STM32F407..

I refer to the attachment. I am using a push button to power on a STM32F303. As soon as the push button is pushed a P channel FET is activated supplying voltage to the STM32F303. As soon as the STM32 starts it activates a pin which takes over activat...

Resolved! Real-life UART with DMA using HAL ?

Hello,Is it possible to use uart with dma, so that on idle we also get informed, so that we can read the rx data ?I found no example in hal cube for using UART with DMA in such "real life" scenario, only in simple full buffer fill - which is not prac...

Trying to integrate the waveplayer from stm32137 example in L4+ MCU. However, the loop updating the DMA buffer only enters DMATxComplete on 3 occasions?

Here's the essence of what I have at the moment. I wonder why it does not enter DMATxComplete, I have tried with 128 and 30 buffer sizes...//****** dac.c **********//   DAC_HandleTypeDef hdac1; DMA_HandleTypeDef hdma_dac_ch1; DMA_HandleTypeDef hdma_d...
