In the UK RS will sell you all the bits needed, and when you order it lists
a few but I can't remember if it included everything. I ordered an SD Card
with OS installed. I can't remember if I was offered the USB keyboard but I
did order the 4gb card with OS installed.
Right.,..
Having looked on the web a bit more, I've now seen the schemaitc and the
data sheet on most of the main IC ('SoC') o nthe Rpi. And I've read that
a printed user manual is going to be available.
I think the Rpi was released before it was ready. When it first came out
there was no schematic. There was no preloaded SD card avaialable that I
could find. And so on. Things have chenaged, I wil lagree, but IMHO this
should all have been avaiable when the product was anounced. It also
seems to still be the case that demand exceeds supply and that uou can;t
just go and get one. This is a major turn-off for me.
One thign that still seems ot be missing (but it appears people are
workign on it) are routines ot talke to the GPIO fetures. I would have
expected a library with routines to send/receive data to I2C nad SPI
peripherals, etc.
One other quesiton. Is there a linux devief driver for the 'UART'? Can
you acess it as /dev/tty1 or wahtever? Heck, can you ru nthis thing with
a serial termain as a console? :-)
