I create a two threads and used a global variable to communicate between them but it failed. I want to know that if each thread is a different process or a sub threads in a single process.

Different from PC OS,it's hard to describe the rt-thread's thread is a process or a sub-threads, these points may help you understand it:

  1. different thread in rt-thread share the same memory space, so the global variable and other ram space are accessible between threads
  2. each thread has its own context, so the general registers, local variables, are separated

I fixed the problem myself. After writing the else part the program ran correctly without any error.
