this project was made for fun and maybe some advertising but the code drives an 128x48 pixel-led dot matrix assembly controlled by max7291 constant curent led matrix driver.

• -using ATMEGA 1284P MICROCONTROLLER and 2088AS led matrix
• -code is written in assmebly language , compiled with microchip studio
• -it uses simple comunication through UART with an HC-05 bluetooth serial interface for changing text and various settings
• -reads time and date from NEO-6M GPS Module
• -reads temperature with DS18-B
• -using different fonts
