• Modification is not required if the compiler does not support the task function for RTOS.
• When changing to the task function for RTOS, modify the program according to the method above.
From this C compiler to another C compiler
If the #pragma rtos_task specification is deleted, the RTOS task function is used as an ordinary function.
To use as RTOS task function, modification is required according to the specification of each compiler.
