example_dsp.cpp

This example reads both DSPs to get voltage, current, power and grid data.

put 1 Current: 3.67 A
Input 1 Power: 976.95 W

Input 2 Voltage: 269.17 V
Input 2 Current: 3.71 A
Input 2 Power: 996.11 W

Grid Voltage Reading: 236.19 V
Grid Current Reading: 8.14 A
Grid Power Reading: 1909.63 W
Frequency Reading: 50.00 Hz

DC/AC Conversion Efficiency: 96.79 %
Inverter Temperature: 48.75 °C
Booster Temperature: 45.75 °C

The output is equivalent to "aurora -a 2 -d 0 /dev/ttyUSB0"
