External interrupt not working. Why?

Hi. I have two sensors connected to an STM32f410r8t6, where they send a high signal whenever new data is ready to be read. Pin connections are as follows: PC9 (GPIO_EXTI9) -> INT_IMU2PC7 (GPIO_EXTI7) -> INT_IMU1I have them setup as follows in the ioc...

SPI - SDO long tail

Hello,I am having problems with STM32C8T6 interfacing with TI ADS8317.Long tail at SDO line (first & second image)The seperation time between each byte is always significantly long (not sure if this is a problem) ( second image)Second image is the en...

STM32H745 Extenal Flash QSPI

We are using STM32h745XI board with external memory. But the DISCO board has two QSPI flash 64MB each and total of 128MB. Where as in our custom board we used only one chip as 64MB.But in the project file there is no flash algorithm file for 64MB onl...

Hi - I cannot find the link to the Workshop

Documentation and IDE for STiH207-IKB

Hello, I need a hardware / programming guide and IDE support for STiH207-IKB. Where can I get those information ? Thanks a lot.

Hi, I use STM32F746 to build a modbus environment which connected to RS485 bus.I use as DE-RE pin is not a specially defined alternative function pin, so I defined it as output pin.However I am having a problem receiving the packages I send.
