Dear Sir or Madam:

We often read such code like

#define THREADSTACKSIZE 1024 or #define TASKSTACKSIZE 768.

My question is : how to get a right value for THREADSTACKSIZE or TASKSTACKSIZE ?

Thanks a lot!

Hi,

What do you mean by "right" value for stack size?

How big a stack your task needs depends on the task and what variables are defined in the task. One way of profiling the task stack size is to start with a big stack, letting the program run for a while, then looking at the peak stack size in ROV.

Is there a method to calculate or predict the task stack size ?

Hi,

There is no foolproof way of calculating this.

You can use the following method: Set a high task stack value, then run your program for a while. Look at the peak stack size (you can find this in the task view of ROV). You can use the peak stack size plus a buffer value as your stack size.
