My Research As the desire to create a digital Oscilloscope, for almost a month I've being do some research, I finally succeeded in creating a tool that has a function for analyze the voltage level with a range from 0 to 5 volt. The tool is designed to be interfaced to the computer via serial port. Voltage level will be displayed in the graph is voltage (mV) against time (ms). With the distance time from one data to another data is 10 ms.
Software and hardware description This software is created with Delphi 7.0,it is to show the voltage level into the graph. The software needs microcontroller that send data to the serial computer (PC / Notebook). Voltage level that can be displayed is a TTL logic-level voltage between 0 to 5 volt. Graphic results of voltage level readings can be stored in the form of image with the extension *. jpg.
Data shown as
realtime data.
