Undeclared functions and variables

[itr1718]

• Hello

I am working on kds with MKL27Z256 MCU. I want to print real time and wrote some functions and variables such as clock_gettime, CLOCK_MONOTONIC and struct tm. But I got errors about them. Errors said they are undeclared. Of course, I set also time.h.

Why is there the problem and how can I solve this?

Happy new year!

Hi irt:

The ANSI library provides several functions to get the current time. In an embedded systems environment, implementations for these functions can not  be provided because different targets may use different ways to count the time.

I would suggest you write your own functions with the real time clock component on your board.
