Arduino Code for MCP3903 Energy Measurement IC (SPI Communication)
Budget: €100 – €250 EUR
I am looking for an embedded systems developer to write Arduino code to communicate with the MCP3903 energy measurement IC from Microchip using the SPI interface.
The goal of the project is to read voltage measurements from three channels of the chip and output the values through the Arduino serial monitor.
Hardware:
Arduino board (Arduino Uno or compatible)
MCP3903 analog front-end IC
SPI communication
Requirements:
The code should:
Initialize SPI communication between Arduino and the MCP3903.
Configure the MCP3903 registers correctly for basic operation.
Read measurement data from the following channels:
CH0
CH1
CH2
Convert the raw ADC data into readable voltage values (or at least raw measurement values).
Print the measured values continuously to the Arduino Serial Monitor.
Example serial output:
CH0 Voltage: X.XXX V
CH1 Voltage: X.XXX V
CH2 Voltage: X.XXX V
Deliverables:
Complete Arduino .ino source code
Clear comments in the code explaining each step
Instructions on wiring Arduino to MCP3903 (SPI pins and control pins)
Any required configuration constants or register settings
Additional Notes:
No Arduino library exists for this chip, so the code will likely need to communicate directly using SPI.h.
The implementation should follow the MCP3903 datasheet register map.
The code should be stable and easy to modify later.
