Hi,
I have experience for 15+ years in electronics/embedded development. I have several years of advanced AVR/arduino development, including library development from scratch. Practically all Arduino boards used, like: 2009, 2010, UNO, MEGA, NANO, MICRO, MINI and others like DigiSpark (attiny85) and DUE (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 have never worked with the Dali interface/protocol, but in my full-time job my main task is implementing communication protocols for fuel dispensers, so I think I can provide you with the help you need to get this project working.
There is one minor problem though - I don't have any Dali device, so there's 2 ways we can go on with this: I will get your requirements done through Dali emulation (one arduino as Dali master and several as Dali slaves), or you send me the required hardware that will be returned to you when the project is complete. The shipping charges would be handled by you and out of the scope of this bid.
If you are interested in my bid, feel free to contact me.
Best regards,
Carlos.
