Abstract
PURPOSE:To inspect an analog input signal in a short time, by making a self-diagnostic program run by a signal of a test switch which has been provided on the outside of a device equipped with a microcomputer muCM incorporating A/D converter. CONSTITUTION:When an electric power source 100V is connected to a controller 1 which is provided with a muCM5 incorporating an A/D converter 7, voltage Vcc develops, and the muCM5 starts its operation. When a test switch SW9 is turned on, the voltage Vcc is supplied to an input terminal I0 of the muCM5, the muCM5 decides the SW9 two times through the terminal I0, and enters a self-diagnostic program PG only in case when the SW9 is turned on both two times. The self-diagnostic PG permits a timer interruption, and after that, A/D-converts an analog input, decides whether a bit ''0'' of a conversion value is ''0'' or ''1'', turns on an output terminal O1 of a corresponding muPC6 and turns on a LED LE1 in case of ''1'', and turns off the LE1 in case of ''0''. Subsequently, all the bits are decided in the same way. Accordingly, whether an LED executes a decided binary display or not is adjusted by a resistance VR, seeing the LED.
