To Program the SpokePov...
is the 25 pin connector required... or can I just use a 9 Pin Serial Connector. (I have tons of Serial connectors from old motherboards, from some com2s that were located on a card slot cover).
I would really like to use one of these connectors

Seems an easier interface than the 25 pin connectors?
anyway...
thanks for reply..

Actually, what I think I'd really like to have would be SD memory chips on the SpokePOV - slip the SD into the `puter, copy files (quick! ), slip it into the SpokePOV, done - no cables (no communication hassles), no python (which won't run on my old computer - Win ME) and my desktop, laptop or PDA could do it. Leave the board on the cycle and I could carry pre-recorded chips so I could change the images anytime.
Of course this would require a complete re-design of the board

I would guess that one would need a beefier microcontroller for this. While SD cards, per the standard, are required to support the older SPI/MMC transfer mode (even in the dumbed-down 4-wire setup), the transfer isn't the same, so it wouldn't be that easy of a hack. It would require implementing some more powerful stream manipulation on the chip; not a one-banana job, but by no means impossible or difficult.foobert wrote:actually, sd cards can be accessed over the same spi interface used for the eeprom and shift registers. if there's a pin available on the tiny2313 for chip select on the sd card you ought to be able knock out a hack pretty quick.
And then there's the issue of writing data to the card...

Issue, what issue? You pop the SD chip into the port (more and more computers are coming with various chip ports) and copy the data. All you'd need would be something to convert from your artwork to the format SpokePOV can understand.jof wrote:And then there's the issue of writing data to the card...
An additional plus, it would be possible to have more frames, so more complex animations & SD chips that small should be inexpensive
