pio nixie NTP Client v2

pio nixie NTP Client v2

概要

以下のnixieクロックにＮＴＰクライアントの機能を追加する(V2)

Wio nixie tube clock

本記事は「 nixieクロックにＮＴＰクライアントの機能を追加する 」の第２版にあたる。 これは、wio-terminalのWiFiファームウェアのアップグレードに対する対応になる。(wio-terminalのファームウェア・アップデートについて(v2)(linux版))　　　

NTPクライアントの機能を追加しているので、RTCのハードを追加する必要はない。 (ホストPCとしてはubuntuを想定している)

プロジェクト wiot-nixie-NTP のディレクトリを作成する

mkdir wiot-nixie-NTP
cd wiot-nixie-NTP
# 以下を実行して必要なファイルを作成する
pio init --board seeed_wio_terminal

# platformをupdateする
pio platform update

nano platformio.ini
