Graphing Calculator

A Graphing Calculator I made only using logic gates. Plots a graph in about 4 min! Can plot cubic and squared terms. Features a 31 x 31 pixel screen to plot from (-15, -15) to (15, 15). All logic is 16 Bit so can handle fairly large numbers. Inputted numbers can only be 255 max. --> (Ver 1.1) Completely rebuilt screen to use far less logic blocks, can now be spawned on lift! -- TO USE -- Enter your equation on the left input panel and hit the green button on the numpad to begin. To clear the current equation press the red button on the numpad. To change whether negative or positive values are plotted use the > < button on the right. Enjoy Graphing! :D
