Introduction This project demonstrates an Adafruit Trellis Shield latching keyboard test using the ATmega328P controller in a Proteus simulation environment. It is a simple but useful microcontroller project for learning how a keypad-style LED button matrix works with an Arduino-compatible AVR controller. The system reads button presses from the Trellis keypad and toggles the matching […]

Arduino TFT LCD displays bitmap from SD card

Bitmap Drawing on TFT LCD using ATmega328P with Proteus Simulation

AVR ATmega Projects, Circuits, Development Board - Kits Projects, How To - DIY - Projects, Memory - Storage Projects / Ibrar Ayyub

Introduction This microcontroller project demonstrates how to draw bitmap images on a TFT LCD using an ATmega328P-based Arduino AVR setup. The image file is stored on an SD card and loaded directly onto the display through the SPI interface. It is a useful Proteus simulation for learning how SD card storage, TFT LCD control, and
