If there are no errors, click on upload to load and execute the program. Now, go to the tools menu, click on board, and select Arduino Mega 2560 or Mega ADK, if not already selected. With the program loaded in the IDE, scroll down to view the following code: // Uncomment the next line for Arduino 2009/Uno //UTFT myGLCD(ITDB32S,19,18,17,16) // Remember to change the model parameter to suit your display module! // Uncomment the next line for Arduino Mega UTFT myGLCD(ITDB32S,38,39,40,41) // Remember to change the model parameter to suit your display module! Comment out the command for the UNO, and uncomment the command for the Mega ,as I did. If the UTFT option is in your menu list, select it, then select arduino, and finally, UTFT_Demo_320x240. If the libraries installed properly, you will see the UTFT and the UTouch options when you click on the Files option, and scroll down to examples.

If you haven't done so, download the UTFT and UTouch Libraries, and copy them to the libraries folder where you have the arduino IDE installed.

If you finished putting your kit together, plug it into the USB cable that connects to your PC running the Arduino IDE. The oscilloscope, like my 4 channel DC DVM, will not be as accurate as a commercial unit, but it works pretty good for low voltage and low frequencies. A trigger is used to capture and stabilize the waveform on the screen, or to wait for an event before capturing the data. In most cases you can set the trigger level to a voltage value of your choosing. A trigger signal can be generated when the signal value reaches some particular level - the trigger level.
It is usually measured in volts/centimeter or volts per division. That's the measure of how sensitive the display dot is to voltage applied to the input terminals. Sweep speed is usually measured in units of time per distance, like milliseconds/centimeter or milliseconds per division.This might also be referred to as the horizontal sensitivity. These are functions you can control on most oscilloscopes: Sweep speed. Before we start building and programming, lets review some basic characteristics of an oscilloscope. We will be using the Arduino analog A0 input to sample and capture time varying signals by Writing a program that will also display those signals in a 3.8" TFT LCD touch display, and we will input data to modify the oscilloscope behavior, using the touch capabilities of the screen display. You will learn about the Arduino mega analog to digital converter( ADC). We can use an oscilloscope to observe and study signal characteristics that we could otherwise not see. Any time you have a signal that varies with time( slowly, quickly, and /or periodically ) you can use an oscilloscope to measure it, visualize it, and to find any unexpected features in it. It is mainly used to measue time-varying signals.
