Hello,I am working with:NUCLEO-H745ZI-Q => STM32H745ZI-QZIT6U => 144-LQFPRM0399 Rev 4DS12923 Rev 2AN 5354 (Getting started with the STM32H7 Series MCU 16-bit ADC) According to DS12923 Rev Table 96 note 3 is that Table 96 values:"These values are vali...
I am working on a project that needs to integrate a 240x240-round display. The display uses a GC9A01A driver, and the host communicates with the driver through an 8-bit 8080 parallel interface. The display vendor provided this interface for communica...
When I use the UART_Printf example to output an array of size 1024 (or larger) via printf, the program seems to freeze and doesn't output any information after being downloaded to the STM32WB55 Nucleo board. However, when I reduce the array size to 6...
I try to build a code example where I can execute directly from external OctalSPI flash.I use HAL project "XSPI_NOR_MemoryMapped_DTR" as reference and starting point:It works fine: I can write (flash) and read back external QSPI memory. I can also ex...
Hello,I have a problem with STM32N6. When trying to access any TCM (ITCM/DTCM) the CPU immediately crashes to the Hard_Fault. Do the TCM memories need to be explicitly enabled or something? From my experience from STM32H7, it was never needed. I've l...
Hi everyone,I’ve been working in IT for a while, focusing mainly on cloud computing and Linux environments. However, I’ve recently become really interested in embedded systems and the potential for integrating hardware and software solutions.I came a...
I have to read a 20-bit SSI signal. I connected it to a SPI interface as a “Receive Only Slave”.It appears that the SPI interface is limited to 16-bits.We could live with the first 16-bits of a 20-bit word. Can the SPI receiver do that?
Hey, I'm having some issues with setting up clocks for my STM32F411CEU custom board with HAL.Using PLLCLK from HSI ends up with Hardfault, around where RCC is being configured.The only way I don't get hardfaults is:1) if I set System Clock Mux to HSI...

Hello, I am trying to send a message using SPI DMA. I also enabled UART DMA. When both of them are executing, SPI DMA does not work. I implemented SEmaphore Mutex as well. Below are my code and SPI and UART drivers. Can anyone help me --------------...
