The robostix I/0 page says that the gumstix GPIO lines 34 and 39 are brought out through the HiRose to the robostix. In experimenting with them, it seems that 34 is *only* a recieve pin and 39 is only a transmit pin. I can't reconfigure them through /proc/gpio/GPIO34 and 39. It seems that there is no way to configure them as general GPIO pins.=20 This doesn't work for GPIO39. echo GPIO in >/proc/gpio/GPIO34 echo GPIO in >/proc/gpio/GPIO39 Is this the case? I need two GPIO input ports on the gumstix/robostix combination. Chris |
