Design an autoranging voltmeter. The three ranges are 0 to 2 V, 0 to 0.2 V, and 0 to 0.02 V. The hardware/software system automatically adjusts the range providing the best possible measurement resolution. Display both the numerical and graphical results on an LCD display. The HD44780 LCD allows you to define up to 8 new character images (ASCII codes 0 to 7). By dynamically setting these 8 by 5-bit characters, you can create an 8-bit high by 40-bit wide graphical image. Write a graphical device driver for the LCD and use it to graph the time-varying voltage in real time. Experimentally determine the measurement resolution for each range and compare it to the expected theoretical resolution. Analyze the various sources of measurement error in your system.
