Hi Joel-
Thanks for your response! I think you're answering a slightly different
question than I'm asking, probably because my question was screwy.
To restate my question, whichever numbers we use to refer to the pins, how
do I address those pins via sysfs? These are the pin numbers (using Joel's
numbering scheme) that I've been able to successfully address, and use to light
LEDs:
Top down view of the header showing pin numbers (Joel's numbers):
----------------------------------
2 | 4 | 6 | 8 | 10 | 12 | 14 | 16
----------------------------------
1 | 3 | 5 | 7 | 9 | 11 | 13 | 15
----------------------------------
Format: /sys/class/gpio/gpio# -> Pin #
8:1
9:3
10:5
11: ??
12: ??
13:11
14:13
15:15
So, I know that I can address the bottom row of pins using
/sys/class/gpio/gpio8-15 , except for pins 7 and 9. So how do I address pins 7
and 9? One would think, based on the /sys/class/gpio/gpio# pattern, that it
would be gpio11 and gpio12 ; but those don't work. Any suggestions appreciated.
thank you,
Erik
