Hey everyone, Is there a particular pin header out there somewhere that will fit into the LCD holes in the breakout-vx? They are not at .1" like all the rest of the holes in the board, they appear to instead be spaced at 2mm apart and the two rows are offset. I've found some 2mm pin headers at mouser.com and can buy single row headers and solder in two of those, but I thought that maybe the board was designed with the offset holes like that with a certain pin header in mind already or something. Also, as for the signals along the back side of the board (opposite the usb mini-b connector), how many of those are safe to use for GPIO's? I've found a couple of references in the wiki and mailing list that makes me think that for example the MOSI, MISO, FRAME, CLOCK, PWM0, PWM1 BITCLK IN0, IN1 signals have GPIO numbers associated with them. Since MOSI and MISO are associated with SPI, I didn't know if that might somehow tie into the cpu and do nasty things if I tried to use them as normal GPIO lines. The signals behind that are of course for UARTs so those are no-brainers. I guess the bottom-line question is, aside from the LCD signals on the breakout which I know are safe to use for GPIO, which of the other signals on the breakout may also be safely used for GPIO? Thanks! --Pat |
