Problems solved by technology

[0007] However, the above requirements often face the problem of insufficient number of general-purpose input and output pins.
Therefore, designers often have to choose the functions expected to be developed, resulting in limited product development, or need to configure additional general-purpose input and output pin expansion components (GPIOexpander) to expand the pins of general-purpose input and output pins, and Increase product cost and complicate design and manufacturing procedures

Embodiment Construction

[0028] figure 2 It is a schematic diagram of a preferred embodiment of the system architecture of the control system of the present invention. As shown in the figure, the control system 2 can be divided into a control body 20 and a peripheral component unit 21 . Wherein, the control subject 20 is the control core of the control system 2 to realize the special functions of the control system 2 . The control body 20 has an arithmetic processing unit 200 , a signal processing device 202 , and a general-purpose input-output (GPIO) interface 201 . The control body 20 may also have a memory (not shown) for storing system programs. The peripheral component unit 21 is a man-machine interface for providing information about the control system 2 to the user and allowing the user to operate the control system 2 . For example, the peripheral component unit 21 has a light emitting component 210, a key and related circuits (not shown). The light emitting component 210 and the button ar...

Abstract

A signal processing method of a general input/output interface is used to carry a data signal with a control signal. Firstly, a replacement digital signal is generated by replacing time sequence of the data signal. Secondly, the replaced data signal is carried with the control signal. According to the invention, two information signals are transmitted by one single pin to implement objective of using the input/output interface sufficiently.

Description

technical field [0001] The invention relates to a signal processing method, in particular to a signal processing method of a general input and output interface. Background technique [0002] In the development process of electronic products, the designer uses programmable technology to edit the program of its control core, coupled with continuous function verification and debugging (testing) programs, in order to achieve the unique performance requirements of the product. The aforementioned programmable control core includes a microcontroller (MCU), a programmable logic (PLD), and a programmable system on a chip (SoPC). These programmable control cores usually include three main structures, namely, computing processing unit, memory, and input and output unit. [0003] The calculation processing unit is the center of calculation, judgment and control, the memory is usually used to store system programs such as firmware, and the input and output unit is used to receive or out...
