|
|
|
|
|
|
### TL;DR
|
|
|
|
#### Add button support
|
|
|
|
1. Edit `/boot/config.txt` file.
|
|
2. Add line ` dtoverlay=gpio-shutdown`.
|
|
|
|
Final result:
|
|
```

# enable raspicam
|
|
start_x=1
|
|
gpu_mem=128
|
|
|
|
# Simple button on/off
|
|
dtoverlay=gpio-shutdown
|
|
```
|
|
|
|
#### Add LED support
|
|
|
|
1. Edit crontab
|
|
```
|
|
#> crontab -e
|
|
```
|
|
|
|
|
|
2. Add the line
|
|
```
|
|
@reboot raspi-gpio set 4 op dh
|
|
```
|
|
|
|
Final result:
|
|
```
|
|
# Edit this file to introduce tasks to be run by cron.
|
|
#
|
|
# Each task to run has to be defined through a single line
|
|
# indicating with different fields when the task will be run
|
|
# and what command to run for the task
|
|
#
|
|
# To define the time you can provide concrete values for
|
|
# minute (m), hour (h), day of month (dom), month (mon),
|
|
# and day of week (dow) or use '*' in these fields (for 'any').
|
|
#
|
|
# Notice that tasks will be started based on the cron's system
|
|
# daemon's notion of time and timezones.
|
|
#
|
|
# Output of the crontab jobs (including errors) is sent through
|
|
# email to the user the crontab file belongs to (unless redirected).
|
|
#
|
|
# For example, you can run a backup of all your user accounts
|
|
# at 5 a.m every week with:
|
|
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
|
|
#
|
|
# For more information see the manual pages of crontab(5) and cron(8)

|
# m h dom mon dow command

@reboot raspi-gpio set 4 op dh
