The LED string demonstration
Project description: Developing the software and hardware parts for controller of monochrome LED array (graphic and character). The board based on AVR MCU with implemented SD-Card socket, 1-wire interface for temperature measurement (DS18B20 sensors), SPI interface for static-driven LED's array, photodetector for measure external light's level, RS-232 (RS-485/CL optional) interface for PC/modem connection. The device supports FAT32 file system for storage video scenes and fonts. Role: Team leader Responsibilities and Key Accomplishments: 1.Developed code in C, C++. 2.Created circuit 3.Routed Board 4.Collaborated with a 3-member team. Technologies: GCC, Eclipse, C-Builder, LT-spice, Altium designer, Power Expert, Proteus, AVR microcontrollers, TOP-Switch, PFC-Controllers, LED drivers, HEXFET transistors, DC-DC PWM controllers, Power inductors and transformers.
Ten years experience in HW/SW design of embedded real time systems. Strong knowledge of analog and digital circuits, AVR, ARM, C51 microcontrollers, c and assembler languages. Experience in the PCB layouting and it manufacturing.
