CS5460 power meter chip Python library for Raspberry Pi

This is a library for CS5460 Power meter chip written in Python for Raspberry Pi. It uses SPI communication to read measurements from the power meter. Inspired by and modified from an existing C library for Arduino.

Connecting the power meter to the Pi

CS5460 pin	RPi pin
VD+	5V
VA+	5V
GND	GND
SLK	SCLK (GPIO 11)
SDO	MISO (GPIO 9)
SDI	MOSI (GPIO 10)
CS	Any free GPIO pin
RST	3.3V

Installing dependencies

Install the dependencies using

Sample code

def main():
    # Instantiate the chip 
    power_meter: CS5460 = CS5460(pin=25, voltage_divider_offset=1333, current_shunt_offset=0.055)
     while True:
        # Print the values of each register 
        print(f"Power: {round(power_meter.get_power(), 2)}")
        print(f"Current: {round(power_meter.get_current(), 2)}")
        print(f"Voltage: {round(power_meter.get_voltage(), 2)}")
        print(f"Energy: {round(power_meter.get_energy(), 2)}")
        print(f"RMS Voltage: {round(power_meter.get_rms_voltage(), 2)}")
        print(f"RMS Current: {round(power_meter.get_rms_current(), 2)}")
