Hi I have recently started learning PIC programing. So far made 2-3 programs, playing with LEDs. Before proceeding further for astable multivibrators, I have a question: For a high frequency (say 1KHz) astable vibrator, is there any specific keyword to have the required output or we have to manually set the ON period+OFF period to define one cycle and then repeat it? If there is some specific keyword, please let me know. Thanks. p.'s. I am using PIC Basic.
