Resolved! STM32L562CET6 won't enter EXTI callback function.

I am quiet new to STM32 programming and can't get the external interrupt to work.I started with the NUCLEO-L011K4 and wrote my programm without any issues. I switched to my own board (pdf included) and weren't able to get extrenal interrupts to work....

ADC

Hi All,I would like to configure my ADC such that it is able to read from 2 channels. And that the conversion of the channels will be stored in the memory through DMA. But most importantly, I want the conversion to be triggered by a TIMer's rising/fa...

STM32H743 out of sequence packet issue

HI,I am using stm32h743 controller and trying to port http webserver application which was working on stm32f7 platform. the application is using socket based apis. here i am generating the code using stm32cubeMX with STM32Cube_FW_H7_V1.9.0 package. A...

When exactly does SPI TXE get set in an F730

I am trying to change from using a Timer PWM controlled outgoing bit stream to an SPI controlled outgoing bit stream. It would be very nice to output a 32-bit word in one shot using the 4-byte FIFO at each TXE interrupt, but the RM seems to indicat...

Resolved! TIM1+DMA Driven GPIO transmit speed limit

I am using STM32F407ZGT6 and configured the TIM1_CH1 to trigger DMA2 to transmit data through GPIO. Since the protocol is using both raising and failing edges, I need to control both data pins and the clock pin. So the TIM1 is just generating PWM sig...

Resolved! How can UART_Tx impact neighboring GPIO pins?

I have a STM32G071 where, among other stuff, an UART interface an a GPIO input are configured. UART is mapped to PA9 - PA12 (Tx, Rx, CTS, RTS). PA8 is configured as GPIO input mode (no pull-up, pull-down). On the net connected to PA8 is a hall sensor...
