Hello, I am using STM32L4R9AI, the MCU VDD is powered at 1.8v and VDDA at 3.3v. in the recommended design by ST, there is ferite bead between MCU VDD and VDDA, ferite bead is basically inductor which acts as short circuit for DC current, so how can I...
Hi,I'm using a dual core H7 and I'd like to use the only the M4 in some situation, having the D1 domain in Stand-by.It seems that there is no example for such configuration and I'm struggling to make it work by myself.I'm wondering what shall be the ...
This MCU has 1MB Flash which can be configured with the DB1M Bit in the OPTCR Regs of Flash Controller. Default is DB1M=0, which layouts the flash in single bank mode in 12 Sectors.DB1M=1 layouts the flash in dual bank mode with 2x 8 Sectors.When DB1...
Hi,I'm using DWT library to generate us_delay.#include "stm32f7xx_hal.h" // change to whatever MCU you use #include "dwt_delay.h" /** * Initialization routine. * You might need to enable access to DWT registers on Cortex-M7 * DWT->LAR...
Hello everybody,I use the STM32H743 and try to flash it via UART, which usually works quite well.I would like to know whether it is important to de-energize the controller before connecting the programming adapter or the adapter must be connected und...
I'm using STM32F767 Nucleo-144 and am trying to get the SPI 4,5 and 6 working. SPI1-3 work fine. On the Nucleo Board manual I don't find any reference to SPI4-6 at all. So it is possible that those SPI aren't working on the Nucleo Board for some reas...
In the STM32F4 Repo, there are a lot of projects, but I can't find the pre-loaded LED-Blinking example anywhere.
I'm using stm32f105VC. I have enabled the WWDG clock in RCC_APB1. I'm writing to WWDG registers.The problem is that WWDG doesn't start. The printed value is 0x7F - always the same. I've checked also registers by Truestudio - both CFR and CR always ha...
