Resolved! SYSCLK vs SystemCoreClock

Hello,I want to know difference between SYSCLK and SystemCoreClok.When ı try to configure clock of different peripherals I saw terms SYSCLK and SystemCoreClock. I use MSI for SYSCLK which is configured to 32MHZ and for cpu1 ı divided sysclk by 4 and ...

Resolved! STM32WB55 enable IPCC chage clock and broken usb

I'm generating code with STM32CubeIde 1.11.0 for a STM32WB55, in my test project there is an USB CDC and BLE is enabled.When I enable BLE also IPCC must be enabled, but after HW_IPCC_Init is called usb clock is wrong so my usb device doesn't work any...

Resolved! I have some trouble with my st32cubeMX. I can not enable the EXTI on line 2, why ??

The enable boxed are there, but only for EXTI line 2, it's greyed out.

hi team, i have one question can i use external j-link debugger for remove RDP and write protection and also flash the code into the controller(STM32WLE5JC) LORA-E5 board. and also please provide j-link debugger software to remove protection.

hi team, i have one doubt. what is the use of arduino extension connectors in stm32wle5jc controllers. and what is morpho extension headers and what you mean direct access to all MCU I/O's can you explain clearly what that means.
