Hi, My project is to implement a real time signal plot on a VGA display, a kind of oscilloscope output(but not exactly). I use the adc on LogicStart Megawing to get the data (a sound signal from mic- attached to a stethoscope to obtain heart sounds) and just want to get its amplitude waveform displayed on a VGA display in real time. I am afraid, but I have not written any code to show you. I am unable to understand a method (logic/program) for accomplishing the task. Hope you will help me to overcome this difficulty. Regards, Tom
