Title: RP2040 and INA219, 3.2-inch GUI for DC Voltage, Current, and Power
Post by: hesam.moshiri on December 24, 2024, 12:35:37 pm
This project involves designing and implementing a voltage, current, and power meter circuit, leveraging the powerful RP2040 Zero microcontroller, the precision INA219 sensor, and a 3.2-inch ILI9341 SPI 320x240 TFT display. The RP2040 Zero, featuring a dual-core Arm Cortex-M0+ processor running at up to 133 MHz, provides ample computational power and I/O flexibility for real-time data acquisition and processing. The INA219 sensor, known for its high accuracy and wide measurement range, offers shunt-based current sensing and voltage measurement capabilities, with a resolution of 12 bits and a maximum voltage range of 26V.

The 3.2-inch 320x240 TFT display, with its vibrant color rendering and responsive interface, provides a user-friendly graphical interface for displaying voltage, current, and power values.
