My name Didi Avram. How to read entire port (Example PORTD) connected to external ASC. I use STM32F401.

The difference between BOOT Loader and DFU mode??

I'm studying about the DFU mode to use this.​So I'm looking for documents, but I'm confused whether the DFU mode and BOOT Loader are different or the same.​I think,​There is ​various ways to communicate with the MCU in Boot Loader state like UART, I2...

stm32F0 CDC out of work after vector-table relocation

Hi,I have an application running on the stm32F072C8U6.It has a 'bootloader' application at 0x08000000, which successfully jumps to the 'real' application, at 0x08004000. after vector remap, GPIO USB Keypad works fine, but when PC send a message by US...

I am having working tcp/ip project using lwip on STM32F7 using which I can send RAW data.Now I want to send text file from SD card to local server.How can I implement this.

FreeRTOS contest switching time from ISR

Hi all,In my project I need to read an ADC at a sample rate of 15KSPS. When new data becomes ready to read, the ADC pull low the DRDY line. I've configured this line as input interrupt and in the ISR a signal is sent to a task waiting for it before t...

How do you write/read from pins Pxx_C ?

For example, when using the HAL drivers to write to a pin you would normally write: HAL_GPIO_WritePin(GPIOA, GPIO_PIN_1, GPIO_PIN_RESET);But, how would you do that using PA1_C, for instance?Thank you.

I am wanting to create a USB audio device using the STM32 MCU. I am specifically wanting to connect multiple audio codecs. This needs to be a high quality audio device. I need some advice.

1) Is the STM32 capable of handling multiple audio codecs for audio transmission over USB?2) If so, what development boards would you recommend for getting familiar with it?3) Are there any tutorials for setup? Thanks!!!
