Issue with SPI DMA Transmission Starting from Random Index Instead of Array Start (Circular Mode) (STM32L562VET6)I am working with an STM32L562VET6 and have a 2D array DATA defined as follows: uint8_t DATA[NOS][3] = {}; Here, NOS = 20000, and each ro...

My flash memory is getting erased in stm32 mcu after I power it off and on What could be the reason?I'm using stm32l562vet6 on a custom PCB. Once I upload the program untill the power is on the program executes properly even if I disconnect the st-li...

Hi STM Community,I'm writing to report a critical issue affecting the SPI sampling rate when using the USB device middleware/software package as a Communication device class on an STM32 microcontroller.Detailed Scenario:I'm employing Timer TIM15 conf...

I'm unable to receive the external interrupt from both EXTI1 and EXTI8 interrupt linesThe triggering is set to faling edge detection and the pin is pulled up externally and the push button connected to the pin shorts it with the ground to create fali...

I tired to make it Zero and run againbut it's going back to HIGH state again

No I'm sorry It's not getting erased physically..As you said the program is not starting after the power off and on.And also as I observed now , the program is getting halted even I i press the reset button.Here is the SCB->VTOR value: Where VECT_TAB...

No Sorry, I had not checked with the stm32cube programmer before.Now I did, I compared the memory with the .elf file. It turns out the program is not getting erased but it is just not executing the program.I'm just running the blink LED program to de...

Thanks a lot @SofLit!! ,Changing the callback function from>HAL_GPIO_EXTI_Callback()to >HAL_GPIO_EXTI_Falling_Callback()solved the issue

> So you observe PB8 is changing?I have defined 2 interrupts here i.e,> #define NDRDY_Pin GPIO_PIN_8> #define NDRDY_GPIO_Port GPIOA> #define NDRDY_EXTI_IRQn EXTI8_IRQnand> #define NDRDY_Pin GPIO_PIN_1> #define NDRDY_GPIO_Port GPIOB> #define NDRDY_EXT...
