1. A method of driving a counter system with zero accumulated error comprising:
setting a counter frequency of a counter transmitter;
setting an original time count string according to the counter frequency;
setting a first time count string of the counter greater than the original time count string;
setting a second time count string of the counter smaller than the original time count string; and
accumulating at least one first time count string and at least one second time count string over N cycles for generating a transmitter time count string;
wherein N is greater than two, a real time string generated by the original time count string over the N cycles is equal to the transmitter time count string.
