I have designed an electronic Watt-Hour Meter with MSP430FE427 for Central Viet Nam market.
I have read the datasheet MSP430Fe42xA and slaa203c.pdf .
Please help me the hardware with schematic for E-meter ( Voltage: 220V - Frequency: 50Hz).
I want to use switching power with low voltage dectected module.
I will appreciate if you tell me how to design this schematic.
