5 Years Of Experiences On Embedded System Design
• Independently developed an AC voltage detector utilizing Atmel microcontroller ATTINY25V, this project already generated a marketable product that immediately turning profit of 2,000,000RMB revenue (approximately $323,000) • Self educated in C (programming language), familiar with syntax and embedded design paradigms.• Familiar with MCU peripherals such as Timers, ADC module, PWM, TWI(I2Cbus), and learning more.• Familiar with MCU interfacing to external components, such as LED, speaker, push button, selector switch, rotary encoder, 7-segment display, motor, potentiometer, thermistor, transistor, voltage regulator, crystal oscillator, relay, RTC, and primitive logic chips.• Familiar with development tools, such as compilers, programmers, and hardware for constructing prototypes.• Worked with multiple design constrains, such as multi features competing for processing time, size, weight, temperature, cost, user interface, and battery life requirement.• Independently design and construct the hardware of a prototype or manufacturable product.• Experience working with Atmel AVR (TINY and MEGA) series and Microchip PIC16FX series of chips.• Excellent contribution in senior design project (School), we programmed and testeded a Geneva drive control system using a microcontroller and optical sensors. I was in charge of temperature reading, power supply, and computer GUI (using Visual basic). Developed a data acquisition device using PIC18F4455, record the input waveform, perform Fouriertransformation for frequency analysis, display graphical data on computer screen with GUI made with C#, itoperates in real time. Developed a simple function generator using PIC18F4455, output sinusoidal and square wave with limitedand adjustable frequency, and amplitude. Measurement of the frequency and amplitude of input wave. Good experience in technical report and documentation of embedded system based projects.
