成果简介	NOVELTY - The device has a main resistive divider that is formed by the second and ninth resistors, forming an initial potential on the signal line, a series chain of identical links with a star-shaped connection of the third to eighth resistor. The first to sixth capacitor and the first to sixth key form a priority voltage divider when the first to sixth keys are closed in any combination. The free end of key of each link is connected to the common communication line which is connected to central point of the main resistive divider. The pull-up resistor is connected between the signal lines. The pulse front that forms the hardware interrupt of the microcontroller is transmitted to it along signal line with an amplitude that does not depend on the pressed key which waits for the end of transient processes on the signal line, and then measures the steady-state voltage on it corresponding to the pressed key. USE - Sensor polling device for low power system. ADVANTAGE - The device obtains maximum reduction in the number of signal communication lines, low power consumption, a simple mechanism for forming a common sensor activity signal, and a clear and unambiguous determination of sensor priorities. The device contains a resistive divider, a sequence of forming links, a capacitor for isolating the pulse front, and a pull-up resistor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the interrupt signals for the microcontroller and output voltage levels.
