Embodiment Construction

[0008] As shown in Fig. 1, the present invention includes the connection between peripheral circuits such as light touch switch, pressure switch, infrared remote control receiving circuit, infrared induction receiving circuit, solenoid valve circuit and single-chip shared chip I / O input and output ports, flag bits and embedded A collection of software. The I / O input terminals I / O(1) and I / O(2) of the microcontroller are respectively connected to one end of the light touch switch or pressure switch K1, K2, and the other end is connected to the positive pole of the power supply through a resistor, and the common end is grounded . The light touch switch is a 3 liter and 6 liter key switch, and the pressure switch is installed under the toilet seat. In actual use, select a light touch switch or a pressure switch according to the combination of flag bits. The output ends of the infrared remote control receiving circuit and the infrared induction receiving circuit are respectively...

Abstract

It relates to the design of a single chip shared chip interface and peripheral circuit of embedded water saving sanitary equipment. It has marking positions and embedded software, having the ability of differentiating and selecting touch switches, pressure switches, infrared remote control and receiving circuit, infrared sensing and receiving circuit, electromagnetic valve circuit and other peripheral input and output methods to control different functions of the water saving sanitary equipment. It is beneficial for the standardization and systematic production for the embedded software for control chips of the single chip, saving the resources of single chips with lower cost in production.

Description

technical field [0001] The invention relates to the design of the peripheral structure of a single-chip shared chip, in particular to the design of the single-chip shared chip interface and peripheral circuits of an embedded water-saving sanitary ware, and belongs to the application of single-chip technology in the field of water-saving sanitary ware control. Background technique [0002] The control chip of the prior art water-saving sanitary ware before the creation of the present invention adopts a one-to-one control mode, has single function, high manufacturing cost, secondary development of control software, and long production cycle. Simultaneously, the single-mode control chip causes waste of resources of the single-chip microcomputer chip. Contents of the invention [0003] The purpose of the present invention is to provide a design for the single-chip microcomputer of the embedded water-saving sanitary ware to share the chip interface and the peripheral circuit. ...
