HelloTrying to enable SWV for my STM32L431RB (cortex-m4?)But it is greyed out? I have read that it should be supported on cortex-m4.Any suggestions?

MCU STM32F765GZMy Problem:EXTI_LINE_0-4 has separate IRQ handlers but al are occupied.EXTI_LINE_5-9 share the same IRQhandler and also priority. pin 6 is needed with prio 1(brownout mon)EXTI_LINE_10-15 share the same IRQhandler and also priority. pin...

I wonder How Ican change the init value of the spi crc. the only thing I can see that I´m able to configure is SPI_HandleTypeDef *pSpiHandle; pSpiHandle->Init.CRCCalculation = SPI_CRCCALCULATION_ENABLE; pSpiHandle->Init.CRCLength = SPI_C...

HelloIm trying to implement stm32 spi multi-master function on a stm32f765 according to the below presentationI keep getting MODF error when transmitting as a master, that would indicate that the slave sets the masters NSS pin low. Even if I set the ...

"Since EXTI5-9 have a shared interrupt, you can't separate them into their own interrupts. They are hardwired to share the same one and therefore will have the same priority for all pins."Yes I am aware. I trying to work around this by triggering a s...

You mean that I can steal anyone of the IRQn_Type:s and call those functions with it?..its a big application, but I´ll guess I have to see if theres any one free.Just to make sure: Its not possible to add a custom interrupt handler here right?

I had setting Mode= GPIO_MODE_AF_PP | GPIO_MODE_IT_RISING , this meant that when the HAL function HAL_GPIO_Init checked if AF should be used, the result was faulty ->no AF was set.Anyway, now I have scaled back to only using AFGPIOx->MODER = 0xaaa86a...

I updated the answer just before your postI simply had a break point inside the setup function after the pin configIf your referring to the SFR view, that view does not show the GPIO registers:

So i guess we are on different sides of it, I can´t fully interpret the content of those registers:GPIOx->MODER = 0xaaa06aa0 / 10101010101000000110101010100000 AFR = 0x40020020 / 1000000000000100000010000100000 AFR[0] = 0xa666900 / 101...
