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...
