-# rpi-pictureframe-slideshow-config
+# rpi-slideshow-config
+My crappy little config to have an rpi 3b act as a "picture frame"
+
+## What
+
+this is woefully insecure. i don't recommend using it. use at your own risk. etc. etc. i've spent like 5 minutes on this.
+
+these are my notes-to-self as to how i got this rpi working as a picture frame, that would self-update from a gdrive file share
+
+last performed 2019-06-26
+
+rpi 3b
+
+Dell UltraSharp LCD
+
+HDMI -> DVI adapter
+
+## Instructions
+
+0a. set up an account on a web file sharing doohickey like google drive.
+
+0b. create folders "picturesync" and "configsync" and note where in the path you put them.
+
+0c. put all of the files from this repo in the "configsync" folder.
+
+0c. edit wpa_supplicant.conf to ensure that it's correct for you (it's not by default). refer to wpa_supplicant on a real working rpi3b to get a feel for what it should be like. or google it, i'm not your boss, i'm you.
+
+0d. of course you should also review the rest of the files for accuracy because lord only knows what typos there might be
+
+0e. adjust "cron_frequent.sh" so that your preferred times are used for when the display should be put to sleep
+
+1. download noobs
+
+2. follow the instructions on the rpi official website to get noobs running
+
+3.
+```bash
+sudo nano /etc/lightdm/lightdm.conf
+```
+
+Now in here add the following line anywhere beneath the [SeatsDefaults] line.
+
+```
+xserver-command=X -s 0
+```
+
+4.
+```bash
+sudo nano /etc/rc.local
+```
+
+Add just before exit 0:
+```bash
+bash /home/pi/rclocal_startup.sh &
+```
+
+5.
+```bash
+sudo apt-get install feh
+curl https://rclone.org/install.sh | sudo bash
+rclone configure # Use the knowledge you obtained during step 0 to properly configure rclone. in this doc the remote is called "remoteside"
+mkdir /home/pi/picturesync
+mkdir /home/pi/configsync
+rclone sync remoteside:/configsync /home/pi/configsync
+cp /home/pi/configsync/periodic_sync.sh /home/pi/periodic_sync.sh
+chmod +x /home/pi/periodic_sync.sh

+sudo su -
+mkdir /root/.config
+mkdir /root/.config/rclone
+cp /home/pi/.config/rclone/rclone.conf /root/.config/rclone/rclone.conf
+```
+
+6.
+```bash
+crontab -e
+```
+
+Add these lines:
+
+```
+0/15 * * * * sudo /home/pi/periodic_sync.sh
+* * * * * /home/pi/cron_frequent.sh
+```
+
+7.

+reboot
