1  Using Arduino / Networking, Protocols, and Devices / fetchin own firmware on: April 05, 2013, 08:22:34 am
im busy going through the process of desingning an ethernet device( uno + eth sield)that might have to periodicaly be re programmed with new firmware. is there a library that allows me to download a file from the internet and save it to an sd card( the eth shield has an sd card built-in) and then reprogram my atmel with the file from the sd card.the project im working on might need changes from time-to-time, and i would like to make these updates as painless to my users as possible

dont bother messing with the pin assignments of  the spi pins..  on of the pins on that shield should be chip select or slave select from the cpp file i guess its the motor enable line.. move that one to another pin and adjust the code as required.

the slave select pin was added to spi to allow multiple slave devices to sit on the spi bus  do a youtube search for according to pete  and spi and watch the resulting video clip
