Hello,I need to connect more than 2 MCUs with SPI connection(1 Master, 2Slaves). Here is my Hardware connections :MISO1->MOSI2 && MOSI3MOSI1->MISO2 && MISO3SCK1->SCK2 && SCK3NSS1->NSS2 && NSS3But I don't know how I can select each slave with master (...
Hello everyone !I've recently hit a snag in a motor FOC project of mine: the CORDIC unit on a STM32G431xB doesn't give out similar q1.15 results when the input are 32 and 16 bits.In the current setup, both sine an cosine coefficient are pre-stored as...
Hi,I try build loaders for STM32H533RE using its nucleo board but it fails to read any thing using the cube programmer. i tried with nucleo H753 and it worked. i see that u already did loader for the H5 so would u please explain how or maybe update y...
Hi,I am starting a new post for visibility, hopefully someone can point me towards the right direction.The setup:MCU: STM32H725HyperRAM: W957A8MFYA5I, /CK is groundedOCTOSPI1 is used, its reference clock is 200MHz, so with the Clock Prescaler I am us...
Hello all, I am working with a NUCLEO-STM32H7S3L8 board, but I am unable to connect to it using STM32CubeProgrammer or flash firmware using STM32CubeIDE. However, I am still able to update the board’s firmware successfully.Possible Cause:I suspect th...
I am developing a device that implements the USB device class.According to application note AN4879 "Introduction to USB Hardware and PCB Design Considerations Using STM32 Microcontrollers" it is written as follows:Based on the USB specification, a US...
Hi,I am working with the STM32H7S78-DK board and trying to implement Flash read/write functionality in my project (Touchgfx). Below is my code for handling Flash read and write operations: #define FLASH_USER_START_ADDR ((uint32_t)0x08000000) typed...
Hi all, I have created a new project for the STM32U575RIT6 microcontroller using the attached .ioc file. On top of the auto-generated code, I have made the following modifications:In main.c: while (1) { uint32_t bits = 0; uint16_t adc_value =...
I am currently integrating the AR0144 sensor with STM32 using the DCMI interface with DMA for image capture. The image data is being received, but the issue is that the data is incomplete, and zeros are padded at the end of the buffer.Hardware and Se...
Hello,I have an STM32H743 on a custom application PCB and I need to use the IWDG as well as the standby mode to save precious battery current.I have noticed the following strange behavior:1 - I mass erase the STM32H743 using STM32CubeProgrammer2 - I ...
