Only now I realize that you've initialized the PC87366 to use its internal pull up resistors. Effectively this is equal external resistors of course. The PC87366 datasheet describes the internal resistors as "weak pull up". This rather vague statement suggests to me that the pnp setup may work with the internal resistors configured, but you may have to experiment. Personally I would choose to initialize the PC87366 not to use the internal pull ups with the pnp circuitry. regards again, Jan Hoevers _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
