STM32 HAL flash interrupts

I'm working with the STM32L152. I'm finding that after my code runs for some time, during a write attempt to the EEPROM, the flash controller status register shows the WRPERR and SIZERR bits set, which causes the write to be aborted. This is happenin...

UART Interrupt based program without HAL

I have a weight cell connected to NUCLEO-F401RE over UART. I send specific frames and cell responds acording to these ones. I am able to send and receive fixed length frames successfully using HAL_UART_Transmit and HAL_UART_Receive.The problem is tha...

when my mcu go to the standby mode then if i want to trigger extern interrupt after wakeup it is going to isr how its poosible to go isr and why i want when i give the external trigger during standby mode then it will start from the intial not a isr

how to read and write to internal flash in STM32f303CB .

HI, i am doing project on fan controller , i need to measure power factor between my voltage waveform and current waveform which is generated on my CRO. i need to write code to display the powerfactor value. should i use input capture method .

or else do i need to set two GPIO pins as EXTI with rising edge interrupt.i am already generating two waveforms with some dealy . But should i use Input capture method to capture the values at rising edge at each pulse and need to count the number o...

STM32F746 Discovery QSPI Memory mapped mode issue

Hello, I want to use external QSPI flash memory micron n25q128 in Memory mapped mode  STM32F746 Discovery. I used below code to make external flash in memory mapped mode but I can see incorrect data at external flash. I am not sure whats wrong in m...

I have a NUCLEO-F030R8 card and I want to try to communicate with an SD card. Does ST.com have any libraries for this?

And, is there some tutorials somewhere for this kind of things?I am a newbie, and I don't know where to navigate for these kind of things...
