Ipod as a gps
A few minutes ago I got to meet a lot information, very interesting…
A person who worked in the late Nemerix (manufacturer of GPS systems) be able to interface with an iPod with a GPS card ad hoc.
For the occasion, was used one of many PCBs that the Nemerix mounted on their dispisitivi, associated with a controller to redirect the data on the iPod.
Thanks to the controller Atmel ATMEGA324, Then, it was enough to understand how “draw” characters on the display of the iPod, and then display the data has been a breeze.

To send video signals to the display of the iPod, it was necessary to make use of the mode AiR, made available from Alpine and BMW to interface with some BMW iPod with preparation, precisely, Alpine.
It has been divided the screen into small squares (Commodore64, do you remember?), and numbers were composed by illuminating different combinations of squares, as a kind of digital display 80s
