Connecting STM32F7 Disco Board to a WebSockets Server using ESP8266
Previously, I had a Raspberry Pi CM4 connected to an existing WebSockets server developed with Django Channels. The Raspberry Pi CM4 received data from an STM32F4 and forwarded it to the server. It also processed commands from the web server dashboar...

Hi!I'm a new STM32 user. I acquired a Nucleo-144 board today and noticed that there are no pins in CN11 & CN12. Just curious why.Thanks in advance.
HAL_SPI_Transmit does not transfer 8 bits
We want to use HAL_SPI_Transmit to send data (master) in 8-bit units.However, even though we have set SPI_DATASIZE_8BIT, data is sent in 16 bits.Is there anything incorrect in the code below? uint8_t *spi_txdata;spi_txdata = (uint8_t *)malloc(2 * siz...
Resolved! STM32F4 clock configuration using register programming
I am trying to change the system clock on my STM32F410RB using register programming. I have setup an SPI protocol to an external DAC IC which needs a minimum of 100ns (10MHz) clock period. The SPI allows for a maximum of 8MHz (fPCLK/2) at default clo...
UART Interrupt Not working with DMA enabled
Hello ,We are encountering an issue with the USART_DMA interrupt method on the STM32G070CBT6 microcontroller. The problem is that data is only received after performing a hardware reset. We expect the data to be received continuously without needing ...
UART Communication Using UART to USB cable.
I'm trying to get a simple UART hello world program to work. It just transmits a buffer once per second. I've enabled UART2, enabled the interrupt, and configured the baud rate, parity, and word length. But when I open minicom I don't see anything. I...
