Abstract

The invention relates to the technical field of electronic computers. Particularly, the improved USB-to-TTL test device and the method thereof are provided. A USB-to-TTL test device capable of monitoring two TTL levels comprises a USB interface unit, an isolation power supply module, a linear power supply module, a signal conversion module, a signal indication module, a signal isolation module, two receiving shielding modules, a sending interface, a receiving interface 1, a receiving interface 2 and an equipment power supply unit. Two paths of receiving shielding modules are added to a traditional USB-to-TTL conversion module, so that the device not only has a traditional USB-to-TTL conversion transceiving function, but also can realize a two-path TTL signal monitoring function.

Description

technical field [0001] The invention relates to the technical field of electronic computers, in particular to an improved USB-to-TTL test device and a method thereof, which can monitor two TTL levels of the USB-to-TTL test device. Background technique [0002] Various debugging tools are often used in communication testing or communication circuit testing. The USB to TTL testing tool can directly test the communication TTL level signal on the controller pin, and display the communication data on the computer monitoring software. [0003] Since the controller receives and sends two TTL level signals when realizing communication, if a traditional USB-to-TTL test tool is used to monitor these two TTL level signals, two test tools are required and two serial port resources are occupied on the computer. , this test method is neither scientific nor convenient. Contents of the invention [0004] The invention provides an improved USB-to-TTL test device to solve the problem that ...
