WebSTM32wb55 HAL_Delay () Function. I have been stuck at a problem. I have been trying to configure HAL_Delay function to work in STM32 BLE_Server example in the STM32WB SDK. However, for some reason, the code gets stuck inside the HAL_Delay () Function. I have searched over the internet and tried the solution to increase Systick interrupt priority. WebUpdate: I found the mistake. The SysTick interrupt priority was set to the lowest (15), so calling HAL_Delay() from an ISR with the same or higher priority caused an infinite loop in the HAL_Delay function. So, take care: If you are using the default HAL settings provided by ST, the priority for SysTick IRQ is set to 15 when calling HAL_Init().

WebSep 28, 2024 · SysTick has indeed a default priority level that is higher than any interrupt, but that's only because at reset, all priorities are set to 0, and in case of a tie, the lower IRQ number wins, in this case, SysTick with -1. On the other hand, it seems to be possible to set up Systick as an interrupt in NVIC as well.
