How It Works

This project establishes a communication pipeline between an NXP LPC2148 32-bit ARM microcontroller development board and a Windows 10 PC running NI LabVIEW. The LPC2148 acts as the core processing and data acquisition unit, executing firmware compiled through Keil uVision4 and transferred onto the flash memory using Flash Magic. Because the microcontroller processes digital and analog signals locally, it needs a way to transmit this data to the host computer for visualization and logging. This is achieved via a serial communication link utilizing USB cables. On the PC side, NI LabVIEW 2020 provides a graphical programming environment to build a customized virtual instrument (VI) front panel. The LabVIEW software reads the incoming serial data stream sent by the microcontroller, parses the information, and displays it in real time. This setup allows engineering students and developers to leverage the heavy-duty numerical and visual capabilities of LabVIEW alongside the low-level hardware control of an ARM7 microcontroller, creating a cohesive PC-based instrumentation system.

Frequently Asked Questions

What is the purpose of Keil uVision4 in this project?

Keil uVision4 is the integrated development environment (IDE) used to write, compile, and debug the C/C++ source code for the LPC2148 microcontroller.

How does the LPC2148 communicate with the PC running LabVIEW?

The microcontroller communicates with the PC via a serial-over-USB connection, transmitting data packets that the LabVIEW software reads and displays on its front panel.

Why is Flash Magic required?

Flash Magic is a utility software used to transfer the compiled hex file from your PC into the flash memory of the LPC2148 development board over a serial interface.
