Hi Expert,

For BIOS system, there have a function that called TSK\_isTSK that know whether the code run from interrupt code or other non-interrupt task code, any API function for FreeRTOS have the same function?

Which FreeRTOS port are you using? Many FreeRTOS ports have the function [xPortIsInsideInterrupt](https://github.com/FreeRTOS/FreeRTOS-Kernel/blob/V10.6.1/portable/GCC/ARM_CM4F/portmacro.h#L179).
