摘要： A logic state detection system for detecting the state of at least one state changing device includes a scanning circuit and a current detection circuit. The scanning circuit selectively activates at least one output line electrically connected with the at least one state changing device. Current passes through the scanning circuit to the at least one output line that is activated. The current detection circuit determines whether the state changing device is in a conducting or a non-conducting state as a function of the current.
