If we're talking about add-in boards, perhaps multiple rows of pins some distance apart (for physical support)? I know some fairly old graphics cards used a setup like that for add-in memory (although the boards were quite small).
Do we need to standardize what signals go over the pine? They are general purpose. Perhaps a half standard / half not aproach? Or perhaps a range of pins with set purposes (40 low/high binary pins, 40 analog pins 0 - 3v, 20 somwthing else)? Setup like that you may be able to just present an interface through the driver for userspace control of the gpio pins which would make writing a driver for whatever hardware you've added much easier. --tim On 10/21/05, dsp Mind <[EMAIL PROTECTED]> wrote: > Hi All, > > Two days before I requested to Tim for details regarding > the planned i/o PINs for OGD.
