Masato YAMANISHI / Mbed 2 deprecated Nucleo_AQM1248A_GT20L16J1Y

AQM1248A LCD + GT20L16J1Y Japanese font ROM with Nucleo

Dependencies:   GT20L16J1Y_font aqm1248a_lcd mbed

Fork of Nucleo_AQM1248A by Masato YAMANISHI

/media/uploads/masato/gt20l16j1y.jpg

STM32 Nucleo L152RE/mbed と Freescale FRDM-KL05Z で秋月 AQM1248A グラフィック LCD をドライブに日本語フォントROM、GT20L16J1Y_font を追加。雪だるまの人のGT20L16J1Y_font ライブラリとUTF-8によるサンプルを流用。

フォントROMのほうはLCDとは別系統のSPIを使用。SPI 信号線にはプルアップ抵抗を付けている(裏面にチップ抵抗)。LCDドライバに組み込んで同じSPIを使うのもありかも。

STM32 Nucleo ボードの電源のページにも書いた通り、Nucleo ボードで USB で電源だけを供給する場合には SB1 をショートします。
