Hi. I'm want to auto-switch between a gpio LCD and HDMI-Out on a Raspberry Pi 3.
I found this guide that I'm trying to follow: https://www.reddit.com/r/raspberry_pi/comments/6lq09q/autoswitch_between_lcd_and_hdmiout/
So I made two different config files, config_lcd.txt and config_hdmi.txt
And now I'm trying to run this script in "/recalbox/share/system/custom.sh", but it doesn't work correctly.
It just says: "device_name=RTK-32V3H-H6A" when I have the both the LCD and HDMI connected. But it never reboots and change the output to the HDMI.
What have I done wrong?
#!/bin/bash
#HDMI connection?
rm -f hdmi.name
tvservice -n 2>hdmi.name
HDMI_NAME=$(cat hdmi.name)
#echo $HDMI_NAME
if [ "$HDMI_NAME" == "[E] No device present" ]; then
LCD_ON=$(grep "hdmi_drive=2" /boot/config.txt)
# echo $LCD_ON
# echo "LCD On"
if [ "$LCD_ON" == "hdmi_drive=2" ]; then
# echo "reboot to LCD"
sudo rm -f /boot/config.txt
sudo cp /boot/config_lcd.txt /boot/config.txt
sudo reboot -n
fi
else
HDMI_ON=$(grep "lcd_rotate=2" /boot/config.txt)
# echo $HDMI_ON
# echo "HDMI ON"
if [ "$HDMI_ON" == "lcd_rotate=2" ]; then
# echo "reboot to HDMI"
sudo rm -f /boot/config.txt
sudo cp /boot/config_hdmi.txt /boot/config.txt
sudo reboot -n
fi
fi
