vi /home/pi/.config/lxsession/LXDE-pi/autostart

ces ntxiv kab

@unclutter -display: 0 -nevents -grab

@xset s off @xset -dpms @xset s noblank

Txhawm rau xiam qhov screen blanking nrog lub neej ntawd LXDE, kho cov ntaub ntawv:/etc/xdg/lxsession/LXDE/autostart.

vi/etc/xdg/lxsession/LXDE/autostart

Tawm tswv yim tawm @xscreensaver hais kom ua (ntxiv # ntawm kev thov ntawm kab)

#@xscreensaver -tsis -txaws

Txhawm rau sim xset teeb tsa koj tuaj yeem khiav xset q tom qab rov pib dua koj yuav tsum pom cov zis hauv qab no

nyiam qhov tsis pom kev: tsis pub tso tawm: yestimeout: 0 lub voj voog: 600 DPMS Xiam Oob Qhab

Kauj Ruam 22: Teeb Linux Infrared Remote Control

Peb teeb tsa LIRC hauv Kauj Ruam #18. Cia nws ua haujlwm kom peb Pi tuaj yeem xa IR lub zog rau thiab tawm cov lus txib rau LCD.

sudo vi /boot /config.txt

ntxiv cov hauv qab no rau cov ntaub ntawv config.txt

dtoverlay = lirc-rpi, gpio_out_pin = 22

tom qab ntawv kho cov ntaub ntawv kho vajtse.conf

sudo vi /etc/lirc/hardware.conf

ntxiv cov hauv qab no

LIRCD_ARGS = "-nkag mus"

LOAD_MODULES = qhov tseeb DRIVER = "default" DEVICE = "/dev/lirc0" MODULES = "lirc_rpi" LIRCD_CONF = "" LIRCMD_CONF = ""

Nrhiav koj lub chaw teeb tsa cov ntawv teeb tsa los ntawm cov npe ntawm cov nyob deb hauv LIRC lub vev xaib ntawm https://lirc.sourceforge.net/remotes/ Rub tawm cov ntawv teeb tsa thiab khaws nws li /etc/lirc/lircd.conf. Hauv kuv qhov xwm txheej kuv siv Samsung AA59-00382A teeb tsa cov ntaub ntawv ntawm no

cp AA59-00382A.lircd.conf /etc/lirc/lircd.conf

Tom qab ntawd koj yuav tsum tuaj yeem sim LIRC nrog lub zog no rau/tawm cov lus txib

/usr/bin/irsend SEND_ONCE Samsung_AA59-00382A KEY_POWER

Yog tias koj nyiam koj tuaj yeem teeb tsa lub sijhawm kom qhib thiab kaw koj lub LCD siv cron. Kho kom raug crontab thiab ntxiv lub sijhawm koj xaiv. Hauv kuv qhov piv txwv cov ntaub ntawv xov xwm muaj zog txhua hnub thaum 8:00 teev sawv ntxov, tom qab ntawv kaw thaum 10:00 teev sawv ntxov hnub 1-5 (hnub ua haujlwm hnub), lub zog rov qab los ntawm 3:00 teev tsaus ntuj (15:00) nyob rau hnub 1-5 (hnub ua haujlwm) thiab tom qab ntawv txiav tawm txhua hnub thaum 1:00 teev sawv ntxov.
