**** BEGIN LOGGING AT Sat Nov 09 02:59:57 2019 Nov 09 03:06:18 I understand now. Nov 09 03:06:39 What .h file would I need in a .c file to handle GPIO pins on the BBBW? Nov 09 03:07:12 And when I ask about the GPIO pins, I mean only two GPIO pins on P9. Nov 09 03:07:50 Say P9.11 and P9.12... Nov 09 03:16:04 I looked at gpiolib.c and it is a monster. Nov 09 04:00:28 Monster! Nov 09 05:15:02 set_: why are you programming in C ? :P Nov 09 08:36:50 Just trying to learn stuff... Nov 09 08:49:41 I am reading out of an ARM MCU book and everything is done in .C for now, i.e. for the Cortex-M.

Wired up and wound up! Nov 10 01:02:51 It done work...ed! **** ENDING LOGGING AT Sun Nov 10 02:59:57 2019
