I've been looking at the Raspberry Pi and I've found that they will also offer an expansion board with more GPIOs. I wonder if there's some option use this board as a 1-wire master or connect some Maxim/Dallas master to it. I see that the creator Gert is active in the comments under this post. http://www.raspberrypi.org/archives/411 Maybe someone more advanced in electronics and 1-wire could ask him about it there? I see and option that there would be an uart port(ds2480b) or i2c for DS2482-800 connected directly to Pi? Or am I getting it all wrong?
I also read in the comments that "This is only the first add-on board we’ll be producing, too; look out for camera expansions and some other goodies next year" And some comments from Gert "That is where the GPIO routing area is for. The Raspberry-Pi has 17 GPIO pins. The I/O extension board can take up to 25 signals. So you have to mix-and-match. All 17 GPIOs from the Raspberry-Pi come out on the long row GP0,GP4,…GP23. You have to connect those pins to whatever you want to use which are the B1..B1 MISO.. etc. pins. Most pins can be connected arbitrarily except the SPI pins. (MISO..CSnB) Also MOTA and MOTB can be connected to arbitrary GPIO pins to give you on/off. For speed control you have to connect them to the PWM pins." He also wrote that the board will be available for purchase but the assembly/soldering and buying IC will have to to be done by the user. However anyone could start selling the as kits. -- p4trykx ------------------------------------------------------------------------------ Ridiculously easy VDI.
