Interface a HD44780 Character LCD with a PIC Microcontroller

Interface a HD44780 Character LCD with a PIC Microcontroller

Introduction An HD44780 Character LCD is a liquid crystal display (LCD) display device designed for interfacing with embedded systems. These screens come in a variety of configurations including 8×1, which is one row of eight characters, 16×2, and 20×4. The most commonly manufactured configuration is 40×4 characters, which requires two individually addressable HD44780 controllers with …

Spectrum analyzer based PIC18F4550

The project demonstrates the implementation of the sound spectrum analyzer for 8-bit microcontroller PIC18F4550 manufactured by Microchip . Spectrum analysis is performed using an optimized fast Fourier transform algorithm (Fast Fourier Transformation, FFT), written entirely in C language. Data Visualization (spectrum) is carried out in real time on a graphical LCD display with a resolution …

The IDE Project

4 prototype boards arrived today. After going over them carefully, I found 4 lines that crossed each other. After some quick surgery with a knife and some solder and wire, the IDE project is now semi portable. The power supply is still out of a PC, so it’s tied to an AC outlet. I’d like …

Our final sign language learner.

Sign Language Learner

Introduction We designed a device that can aid in learning the alphabet in American Sign Language. We built a glove with various sensors to identify the hand position of the user closely and use that to give feedback on what they are doing right or wrong through the LCD display for each letter in the …
