C++ (Cpp) write_hardware Examples

Example #1

File: hi_moxa.cpp Project: OlenkaKa/irp6_robot

// do communication cycle
uint64_t HI_moxa::write_read_hardware(long int nsec, int timeouts_to_print) {

  struct timespec start_time, current_time, read_time;
  clock_gettime(CLOCK_MONOTONIC, &start_time);

  uint64_t ret;
  if ((ret = write_hardware()) != 0) {

    clock_gettime(CLOCK_MONOTONIC, &current_time);

    long int current_delay = (current_time.tv_sec - start_time.tv_sec)
        * 1000000000 + (current_time.tv_nsec - start_time.tv_nsec);

    if (current_delay > longest_delay_) {

      longest_delay_ = current_delay;
      //  std::cout << std::dec << "longest_delay_: " << longest_delay_ << std::endl;
    }

    struct timespec delay;
    delay.tv_nsec = nsec;
    delay.tv_sec = 0;

    // clock_nanosleep(CLOCK_MONOTONIC,0, &delay, NULL);

    nanosleep(&delay, NULL);

    // std::cout << std::dec << "longest_delay_: " << longest_delay_ << std::endl;
    /*
     hi_sleep(nsec);
     */

    ret = read_hardware(timeouts_to_print);
    clock_gettime(CLOCK_MONOTONIC, &read_time);

    long int read_delay = (read_time.tv_sec - current_time.tv_sec) * 1000000000
        + (read_time.tv_nsec - current_time.tv_nsec);

    if (read_delay > longest_read_delay_) {
      longest_read_delay_ = read_delay;
      //  std::cout << std::dec << "longest_read_delay_: " << longest_read_delay_    << std::endl;
    }

  }

// std::cout <<"write_read_hardware ret: " << ret << std::endl;
