/ Logic testing apparatus using breadboard

摘要

The present invention relates to an electrical / electronic experimental apparatus using a bread board, and conventionally, simply configures a logic circuit using only the bread board, and manually connects the points of the logic circuit to the terminal to measure the result in the measuring device.;The present invention is to install the multiplexing relays in a matrix structure by connecting the input and output terminals of the bread board in a matrix structure, and to install a relay unit board in a hierarchical structure to connect and switch the input and output terminals of the bread board multiplely, and switching of the relay unit board. An external I / O bus connector is provided for connecting the control bus for control and the data bus for I / O signals to the outside, and connected to the PC through the connector to graphically display the coordinates of each point of the breadboard in the PC. By selecting the point at the PC and configuring the signal measured at the check point to be analyzed, the path for each check point can be automatically set, and the result can be easily analyzed through the PC.
