آموزش زمان پاسخگویی

[mohamad.nasr]

سلام...
در ماژول cmps 03 زمان پاسخگویی یا جدید شدن اطلاعات در حالت پیش فرض به صورت هر 100 میلی ثانیه یکبار می باشد اما این زمان را میتوان تا 33 میلی ثانیه کاهش و تا 300 میلی ثانیه افزایش داد که بدیهی است در زمان پاسخگویی بیشتر دقت هم متناسب با آن تغییر می کند...
برنامه ی زیر که برای میکرو کنترلرهای AVR هستش با کامپایلر Code vision به صورتی که در این برنامه تونایی دسترسی به هر سه تنظیم زمان پاسخگویی را دارا می باشد.

در این برنامه باید 3 سوئیچ ریستی در ابتدای برنامه با نام های sw0-sw1-sw2 تعریف شوند...(+lcd , پایه های i2c و کتابخانه های مربوطه هم که بدیهی است...)

کد PHP:

void change_delay(void)
{                                       
//change start up delay
                                lcd_clear();
                                lcd_putsf("33ms -100ms -300ms");
                                delay_ms(40);
                                while (1)
                                        {
                                        if (sw0)
                                                {
                                                i2c_start();
                                                i2c_write(0xC0);
                                                i2c_write(12);  
                                                i2c_write(0x55);
                                                i2c_stop();
                                                                                     
                                                delay_ms(20);      
                                                i2c_start();
