akita-arm: raspbianでハイレゾを演奏する（volumio からでないよー）

a)　swapを大きくする編
http://inaba.hatenablog.com/entry/2016/12/13/023251を参考にして

SWAPが少なすぎるし　かつ　マイクロSDメモリでは　これがこわれちゃうので
（マイクロSDメモリには　システムがはいってる）
SWAPを本体から　分離する

cat /etc/rc.local

.
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
fi
swapon /dev/sda2
service dphys-swapfile stop
exit 0

b)ラスビアンで　ハイレゾ編

まず
# aptitude update
# aptitude upgrade
# rpi-update
をします

なので

/boot/config.txt
------------------------------------------
dtoverlay=hifiberry-dacplus
dtparam=audio=on

●あとはi2s-DACを常用にするために

　メニューからPreferences > Audio Device Settingsを選びます。

　デフォルトではSound card の欄にはbcm2835 ALSA(Alsa mixer)しか出ていませんが、HypaerberryなんたらDAC(Alsa mixer)が選べます。

　Hypaerberryなんたら(Alsa mixer)を選び、Select Contorolsをクリックすると、Hypaerberryなんたらの機能が出るので、Analogueにチェックしました。
DSP Proguramをチェックすると、内部のフィルタなどの制御ができます。

　この設定をデフォルトにするため、Make Defaultをクリックします。

　OKを押します。

　これ以降、HDMIではなくi2s-DACボードから音が出ます。

１）日本語環境　

素描だけ

pi　の　パスワードは　raspberry
sudo su で　root権限になれる

aptitude search ipa | grep gothic　ー>fonts-ipafont-gothic

aptitude install fcitx-mozc im-config zenity

dpkg-revonfigure locales

dpkg-revonfigure tzdata

nano /etc/defaults/keyboard

２）wifi access point をつくる

ただ　英語の

https://frillip.com/using-your-raspberry-pi-3-as-a-wifi-access-point-with-hostapd/

のとおり

最終のスクリプトは

./wifi-accessPoint.bat
sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT

domain-needed # Don't forward short names

bogus-priv

dhcp-range=172.24.1.50,172.24.1.55,12h

３）NGINX

nginxの　change ｒｏｏｔは　ー＞　 /var/www/html/
