# De2-115 Peripherals Lab Report

The DE2-115 peripherals lab results were quite interesting, both numerically and visually. In part one of the lab, the results pertained to the largest number a bus could hold. For example, it was calculated that a bus of [17:0] could hold any number up to the limit of 262143 using the equation (1). Also, when the value of X in Figure 5 was changed a certain number of lights would begin to blink on the LEDs above the switches. As the value of X increased the number of the switch that would correspond to the LED that was blinking decreased, as it can be seen in Table 1. The information found from increasing the value of X allowed a value to be determined that would allow the LED marked zero to blink. The value calculated was determined to be a bus of [19:0] which yielded the value of 1048575.
The results that corresponded to part two of the lab were visual results on one of the seven segment displays. Numbers as well as letters that were within the hexadecimal range of 0 - F were displayed on the seven-segment display
