| + | ====Code with Pins==== | ||
| + | Below examples follow the same pin number in the example, gpio415. | ||
| + | ===View pin status=== | ||
| + | * $cat / | ||
| + | A status has to be assigned to a pin for it to have this view, see below about setting pins | ||
| + | |||
| + | ===Setting In - Listen to pins=== | ||
| + | * $sh -c 'echo 415 > / | ||
| + | * This line says to use the file export in that directory, and assgn it to the 415 pin, or XIO-P7. -c has to do with reading the command. Note: export is a high level file you can not read normally | ||
| + | |||
| + | ===Read value=== | ||
| + | * $cat / | ||
| + | You will notice that some of these commands do not necisarily have files associated with them. That is ok. | ||

| + | ===Cleanup=== | ||
| + | When you are done you should cleanup your pins so they are not in or out | ||
