When data size equal to 3 rx buffer last element is true only others are not. I expected all of them is true data. Why it is working like that ? I examine the result on debug modestatic void Init_SPI2(void) { SPI_InitTypeDef SPI_InitStructure; ...
If someone has that information please share, better would be if you can point me to the documentation where I can found the information. We are using the STM32F429ZI nucleo board.
Hello,I’m using STM32L412RB.I'm trying to differentiate between the types of chargersWhen the charger is connected, reboot occurs, and I run HAL_PCDEx_ActivateBCD()/HAL_PCDEx_BCD_VBUSDetect() in MX_USB_DEVICE_Init().After that, in case of abnormalit...
Hi,I am using the STM32L082 and looking for ways to have a watchdog implemented.However during long periods of low power sleeps (e.g. 12 hours) I would like to freeze the IWDG downcounter.Is this possible for the STM32L082? Thanks
Hello dear! I'm developing a new product. I would like use the STM32 F1 series, but I was surprised with this: https://blog.zapb.de/stm32f1-exceptional-failure/The F1 Series don't have RDP Level 2 protection, in this case, what's the most security wa...
I am planning to use ADC with 16 bits achieved using oversampling in STM32U5.But on Datasheet there is no data wrt to ADC oversampling.Can somebody help me with data regarding ENOB, EL,ED when ADC is oversampled. Datasheet : DS13737Datasheet - STM32U...
Hi.I am having some issues trying to use the EXTI module, to implement interruption routines associated to ports.The problem is related to the behavior of STM32 microcontrollers with ports interruptions. In most microcontrollers (i.e. Texas Instrumen...
I need to be able to read an external sensor whose status should be interpreted as received communication. This will either be an analog signal that needs to be processed via an ADC or an external I2C ADC - the result of which needs to be further pro...
I'm looking to use a ITS4200S-ME-P relay to switch a high voltage signal and would like to control that via a UART. Per the datasheet this relay, "can be switched on and off with standard logic ground related logic signal at pin IN."
