Problems solved by technology

This method generally relies on the PC platform. When it is inconvenient to carry a computer and requires multiple serial ports for real-time communication, it will inevitably cause some troubles to engineers, especially in extreme or special working environments. Dependency inevitably creates a certain degree of burden on the engineer

Embodiment Construction

[0021] The present invention includes a power supply circuit 1, a multi-channel serial port communication circuit 2, an OLED display interface circuit 3, a key switch interface circuit 4, a rotary encoding switch interface circuit 5, and a main control circuit 6.

[0022] like figure 1 As shown, power supply circuit 1 provides 3.5V power supply for multi-channel serial port communication circuit 2, 4.2V power supply for OLED display interface circuit 3, 3.5V circuit for key switch interface circuit 4, and 3.5V power supply for rotary encoding switch interface circuit 5. The V power supply provides the main control circuit 6 with a 3.5V power supply and a reference power supply. The main control circuit 6 performs serial communication with the device to be debugged through the multi-channel serial communication circuit 2. The key switch interface circuit 4 and the rotary encoding switch interface circuit 5 jointly select the serial port number and the ASCII code sent by analog,...

Abstract

The invention relates to a handheld serial port simulator. A power circuit of the handheld serial port simulator provides 3.5V power for a multi-channel serial communication circuit, 4.2V power for an OLED (organic light emitting diode) display interface circuit, 3.5V power for a key switch interface circuit, 3.5V power for a rotary code switch interface circuit and 3.5V power and reference power for a master control circuit. The master control circuit is in serial communication with to-be-debugged equipment via the multi-channel serial communication circuit, the key switch interface circuit and the rotary code switch interface circuit are used for jointly selecting numbers of a plurality of serial ports and transmitting ASCII (American standard code for information exchange) codes in a simulating manner, and the OLED display interface circuit is responsible for displaying operation. The handheld serial port simulator has the advantages that the multiple serial ports can be efficiently debugged under an offline condition, data acquired by a simulated sensor are transmitted to the tested equipment by a pure hardware system, and accordingly a serial port debugging tool which is simple in operation and is portable and light is provided for engineers.

Description

technical field [0001] The invention belongs to the field of engineering test tools, and in particular relates to a hand-held analog test tool for realizing serial port communication through a hardware circuit. Background technique [0002] Serial communication is quite common in control type applications. Among the ways of connecting various devices and computers at present, serial port communication is the most widely used and relatively simple to operate. Therefore, the serial communication port has always occupied an extremely important position in the category of system control. The wide use of serial port communication makes the debugging of serial port a necessary step frequently encountered by software and hardware engineers in the process of device communication. How to make this step as reliable as possible, strong in stability, and simple and practical in control operation is a must for every A problem that an engineer working on data communications hopes to sol...
