Hi,
I have experience for 15+ years in electronics/embedded development. You can check my linkedin profile here: [login to view URL]
I have several years of advanced AVR/arduino development, including library development from scratch. Also developed several projects in tools from Atmel like AVR Studio and Atmel Studio. Practically all Arduino boards used, like: 2009, 2010, UNO, MEGA, NANO, MICRO, MINI and others like DigiSpark (attiny85), DUE and Maple (ARM Cortex-M3). Several shields used like Ethernet (W5100, ENC28J60, etc.) with various IP protocols implementation, various graphical TFTs with and without touchscreen and various BUS types (parallel, SPI, I2C, etc.), all kinds of sensors and buses, serial and parallel memories, etc.
I also already have ported libraries from AVR arduinos (like UNO) to ARM arduinos (like DUE and Maple - Cortex-M3) and do the same for the new Arduino Zero (ATSAMD21 Cortex-M0). I am currently waiting for an "Arduino M0" board to arrive in mail, that should be arriving in the middle/end of next week, so I could start working on this on that time. Here's the board link: [login to view URL]
If you are interested in my bid, please let me know some more details about your project and I'll be able to answer you back telling if I'm up to the task or not.
Best regards,
Carlos.
