Resolved! STM32L4xx board has GPIO pin 5 on two different ports (GPIOA and GPIOB) that need to interrupt at different phases of processing. How to initialize PA5 to interrupt initially and the switch to PB5 until done and switch back?

EE designed the board with both pins in use and both needing to wake up from STOP2. At start PA5 must be used to awake. Once awake, switch interrupt to PB5 for normal processing. When normal processing is done, switch back to PA5 and enter STOP2. ...

Faulty pins?

Hey, I made some simple code for my STM32L053C8 Discovery kit to toggle GPIO pins which are connected to LEDs. I used PA0 PA1 and PA2 pins and only PA0 pin responded. Then I turned all GPIO pins high and using LED found some more pins which didn't tu...

Is it possible to run a dual bank flash memory and a SW Watchodg at the same time on stm32F767VI

I am implementing a flash driver on a stm32F767VI. So far the driver works fine until the running with the software watchdog. Of course, the MCU resets on a flash erase to a certain sector.Thanks to the AN4826, I found that I could use the dual bank ...

stm32f407 mem to mem DMA with different Sizes

My data has zeros every 2 bytes.it's like this: 0x55 0x55 00 00 0xaa 0xaa 00 00 0x33 0x33 00 00 ......I want to remove these zeros with address increment feature of DMA.I wrote a configuration for stm32f107 DMA and removed these zeros without problem...

How to calibrate STM32L412 ADC

I have a STM32L412, I am using a 3V external reference but my ADC is not very accurate - it never reaches its full value, even though the voltage present is the same as the external voltage. I want to calibrate the ADC to see if it improves the perfo...
