【Abstract】 In this paper, a single chip computer based test system for NC4213 - motorcycle ignition chip is introduced. By using analog switches and high precision resistances, an auto-test procedure under the control of the computer is achieved, in which the value of RX1 and RX2 - the two important resistances are figured out with great convenience and precision.更多还原
