Resistors have power limits. If a 50R resistor is 1/8W, then the maximum voltage applied to its two ends cannot exceed 2.5V. At this time, the current flowing through it is 0.05A, that is, 50mA. Then ...
Chip MSP430F47197
SD16_A performs 7-channel sampling, 32768 crystal oscillator, OSR256, sampling frequency fs=32768*32/256=4096/s
The sampling frequency of the AC voltage is 50HZ. My understanding is ...
