Hi, I am using the STM32U575.In my application, I have to transfer ADC readings to a destination buffer. I have set the DMA source address to the ADC data register (16-bit), and the destination address to a memory buffer start address. The data width...
Hi,I am using STM32H753 in my designCan I short JTAG reset, NRST of MCU and supervisory IC reset ? Will it create any issue while debugging via JTAG interface?
Body:Hello STM32 Community,I’m facing an issue with EXTI interrupts on my Nucleo-G0B1RE board (STM32G0B1RE). The EXTI interrupt doesn’t trigger, even though the configuration appears correct, and I’ve tested both hardware and software triggers. I’ve ...
How does the bootloader in the STM32C071 system memory generate its 12-character USB serial number string descriptor (e.g. "205537C24236")? I notice some similarities between this serial number and the 96-bit unique device ID at address 0x1FFF7550, ...
I'm developing a tool to gang program STM32 products. I'm currently working on the STM32F411 (reference manual RM0383) and the FLASH_CR register SNB field mentions two sectors: user specific sector and user configuration sector. The user configuratio...
Hello, ST experts PB3&PB4&PB5 pins are configured to SPI_SCLK,SPI_MISO,SPI_MOSI in STM32U595VIT6. The code framework is generated according to CubeMX. It works well when communicating with its partner(TI's 32bit ADC), and HAL_SPI_Receive() is called ...
I'm using an STM32H733 running from HSE clock with CSS disabled.In a normal situation, the used GPIO inputs correctly read as HIGH as they are pulled HIGH by an external pull-up / LVTTL (push-pull) drive, verified with the oscilloscope.After exposure...
Hi.. i'm stuck with this problem for days... i'm not able to store basic data in the G030 flash memory...When i tried to erase a flash page using HAL_FLASHEx_Erase(), the FLASH_WaitForLastOperation() returns a HAL_ERROR... I did not found the issue.....
Hello guys, I am building a product, actually am migrating my product from ATmega to STM MCUs, my requirements exactly are as follows,Cortex M0 or better core, >48 MHz2 Channel 5V DACs1 Channel CAN for OBD2 Interface2 Channel ADCs, at least 10 bit re...
Designing custom board based on STM32F746G-DISCO. I am using the TQFP chip, so a few less IO. The DISCO board uses a 4 wide data, but I do not have enough pins so I will only have 1 bit wide data. I only want to use SD card to be able to upload n...
