The Optimization Experiments

摘要

Once the project is connected on a breadboard as set out in in Figure 1, the T-Board is initially configured in a similar way to an Arduino Uno. The input voltage should be set at 5 V using the voltage-selection jumper, and a 16 MHz external crystal oscillator connected. As we need to measure the current we'll remove the jumper completely and connect the DMM to the voltage-selection pins (black to the center pin, and red to the 5-V pin). In this configuration the DMM needs to be turned to the Amps setting in order to complete the circuit. Next, the fuses need to be flashed to the values in Table 1. Finally, the "version-1" code (software download at [7]) needs to be loaded into Atmel Studio, compiled and then flashed to the microcontroller. This version uses a simple delay loop (implemented in the _delay_ms() function) to time the delays between readings. The flowchart in Figure 2 gives an overview of the code.
