hii, i am using stm32 nucleo g0-b1re i am trying to receive data in interrupt mode, but cant figure out what is wrong, i am new to stm32 i2c protocol.i have used master as nucleo-h743zi2 and transmitting data, but it is not showing anything on minico...
Would STM32G4 performance gets effected if runs at lower voltage (1.8V)? Can the core clock run at max 170MHZ or it will run lower speed?
I am trying to configure the LPUART on my board, but appear to be getting nowhere. I've already configured the PLL to run at 110 MHz, and I changed the appropriate registers (`SW`) to use PLL as the system clock. I've tried flashing the board with Ze...
I am using the NUCLEO-L433RC-P development board and in the process of designing my own PCB.I would like to be able to update firmware via USB, but need to make sure my PCB design allows for this.Currently I have VDDUSB connected to 3.3V, but thinkin...
Hey All,I hope you can help me. I'm trying to bring up my new board, which contains a STM32N657IO. Attached are the schematics. You can assume the 5V supply is working(it is after a few bodge wires). My problem is as follows. I'm trying to connect to...
Hello Friends,I am Using STM32F303 MCU for my FULL Speed USB communication board. Used interrupt transfer.Board is going to use in Noisy Industrial environment.So , Planned to use Shielded USB cable with EMI Chokes ( Both Side ).Cable Length is 1.8 ...
Hi,I am trying to use the STM32H5 CRC unit via HAL to calculate a CRC32 (ISO-HDLC) over multiple chunks.This works correctly via:hcrc.Instance = CRC; hcrc.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_ENABLE; hcrc.Init.DefaultInitValueUse = DEFAULT_...
Title shortened from:"With the STM32U545RE, unable to erase the correct Flash Bank, using HAL_FLASHEx_Erase(), when attempting to switch from Bank2 to Bank1".Please keep the title short. Testing is done with the Nulceo-U545RE-Q board having 512KB Fla...
I came across a discrepancy between two ST documents regarding the behavior of an IWDG reset on STM32H5 devices, and I’d like clarification on what exactly is reset when an IWDG event occurs.Document 1: UM3150 Rev 2 – STM32H5 Safety Manual, Table 9 (...
