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...
"Upgrade error, please try again" with ST-Link

Resolved! stm32g0 freezes in bootloader
Hello,We have a device that runs an stm32g0. I have a bootloader at the beginning of the flash and then 2 pages for config and the rest of the flash for the firmware. The bootloader basically checks if the two config pages are OK and then starts the ...
How to configure DFSDM data resolution and how does right bit shift affect?
Hello,I'm currently working in a project with the Nucleo-L476RG board. Basically, I have a MEMS microphone (AN-000048) connected to the board. The microphone (I pretend to work in stereo mode) sends PDM data and I use the DFSDM module get the microp...
Resolved! STM32H7 Custom Project prototype , power issues
Hi there,this is my first post here. So be gentle with me ;)I been working on a project with STM32H757XIH6 for some time now, but without any success. This is already my 2nd prototype and costed me quite some $$ since it had to be a 8 layer PCB. The ...
