RaspberryPi? †

↑

設定 †

基本的には/boot/config.txtで設定可能。

↑

画面設定 †

ディスプレイからの情報が取れてるか

/opt/vc/bin/tvservice -m CEA
/opt/vc/bin/tvservice -m DMT

現在の設定確認

/opt/vc/bin/tvservice -s

手動で指定する場合は /boot/config で以下のように設定

hdmi_group=1
hdmi_mode=16

上のリストに存在しない解像度 †

1024x600の場合以下のような設定にする

/boot/config.txtに
hdmi_group=2
hdmi_mode=87
hdmi_cvt=1024 600 60 3 0 0 0
hdmi_drive=2
↑

画面回転 †

lcd_rotate=1 (display_loteteはobsolate) どちらもPi4では効かない
0=0度 1=90度 2=180度 3=270度
↑

固定IP †

/etc/dhcpcd.conf

interface wlan0
static ip_address=192.168.13.23/24
static routers=192.168.13.254
static domain_name_servers=192.168.13.254

failed to open vchiq instance †

ffpmegなどで表示される場合 /dev/vchiqのアクセス権がない場合に出る。videoグループに追加すれば良い。

sudo gpasswd -a [username] video

OctoPrint? †

3Dプリンタ監視用ソフト
https://octoprint.org/

↑

インストール †

イメージをDLしてSDに書き込む
https://octopi.octoprint.org/latest

設定 †

/boot/octopi-wpa-supplicant.txt にWiFi?の設定が有るので書き込む。
IPは上の固定IPの設定で固定しておく
