OVERVIEW
MAIN LOOP
This section discusses the dsPIC firmware structure, peripheral resources, important
program flows, and explanations of project files included in the firmware zip files
included with the system. See Appendix D. “50/60 Hz Meter Operation” for
converting to 60 Hz code.
• Calculate all electrical parameters in frequency domain
• MCP3909 device communication
• Detect voltage/current phase order, and determine missing phases
• Generation imp/kWh power pulse
• UART communication
The main loop of the entire dsPIC33F program is shown in Figure 3-1.
