What can I help with first? well... perhaps... something simple like.. a simple program that tests GPIO, assuming that say 4 hard-wires are connected between 8 GPIOs in pairs, turning one into an input and the other an output, then setting 0 and 1 and seeing if it's read correctly... then inverting each pair (out becomes in, in becomes out) and re-running the test. something in either c or python that uses the sunxi-3.4 gpio driver: https://github.com/linux-sunxi/linux-sunxi/blob/stage/sunxi-3.4/drivers/gpio/gpio-sunxi.c that _should_ be exposed as /dev/gpio which should in turn appear in either /sys or /proc... it should be a standard interface, with a standard way to set which banks are activated... you might have to do some digging. l. _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
