使用RP2040-Zero和GC9A01的演示項(xiàng)目來(lái)向每個(gè)屏幕發(fā)送不同的圖像
RP2040-2x GC9A01顯示在共享SPI顯示位圖眼睛和繪制眼睛繪制儀表使用多語(yǔ)言和符號(hào)字體
這個(gè)使用RP2040-Zero和兩個(gè)GC9A01顯示器的演示項(xiàng)目側(cè)重于向每個(gè)屏幕發(fā)送不同的圖像。通過(guò)利用SPI端口的共享使用，兩個(gè)顯示器都連接到RP2040-Zero，允許有效的通信。建立連接后，使用適當(dāng)?shù)拇a將不同的數(shù)據(jù)發(fā)送到每個(gè)屏幕。這允許您在一個(gè)屏幕上顯示時(shí)間和日期信息，同時(shí)在另一個(gè)屏幕上顯示彩色圖形或動(dòng)畫(huà)。這個(gè)項(xiàng)目是一個(gè)令人印象深刻的例子，突出了RP2040-Zero的靈活性和功能，以及使用共享SPI端口的效率。
使用Ardunio_GFX_Library繪制眼部圖形
繪制Gauge樣本(Ms CoPilot幫助完成)
下一步嘗試顯示空格字符，天氣符號(hào)和土耳其字符。
