If the Data cache is disabled to solve dma data coherency, it reduce performance a lot? I know functions SCB_ClearDCache(), SCB_InvalidateDCache() to solve that issue. But there is a risk that an error message will not occur even if omitted by mista...
Hi,I have the following code: which clears the WXTI9_5 interrupts, enables the EXTI9_5 interrrupts and provides an interrupt handler for these.void clearAll_EXTI9_5_IRQ(void) { __HAL_GPIO_EXTI_CLEAR_IT(GPIO_PIN_5); __HAL_GPIO_EXTI_CLEAR_IT(GPIO_PIN...
Hello,I am working on stm32h745. I have to use 3 spi in interrupt mode, then how I can know which spi is get interrupted?
Hello,Today, I'm using the MX25LM51245GXDI00 external flash memory on the demoboard B-U585I-IOT02A to store some data and to retrieve them using STM32CubeProgrammer. In order to do it, after erasing a sector (4K bytes), I configure OCTOSPI2 (dedicate...
Hello everyone!I'm writing a STM32F446RE-based flight computer for a rocket. I want to use internal flash memory to keep some key data like base pressure or flight time. So if a power failure happens, the system can keep the base data.These are the t...
hey thereI have a stm32f103 blue pill board which I wish to generate MHz frequencies on pinC13.I have used TIM1. it starts and interrupts and on each interrupt I toggle PC13like sovoid HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { if(hti...
Hi, I'm using a base64 library to convert my data to my base64 on STM BluePill. everything works fine, but after 5 minutes i receive an imprecise data access violation hard fault error on a for statement. i'm using main loop to run my code every 1 se...
hey there I have a question: can a micro, say stm32f407 detect low power? for example is there a HAL function to indicate VDD lower that 3.3v?(this way any time that power is going, I can for example save everything before power off)
I want to use the STLink BRIDGE API and setup a C++ project. So far the GPIO worked fine, next I want to use the UART. I found the following Warning in the docu: "UART "bridge" is not supported on the STLink USB bridge interface. This functionality i...
