19264液晶屏與單片機(jī)驅(qū)動(dòng)

首先說下19264屏

1926屏是由3個(gè)64*64 組成 64行 192列 其中192列 是64+64+64 =192

它們分別有CS1 CS2 CS3 控制 讓那個(gè)屏顯示 所以 每個(gè)屏最多只能顯示64行64列 切結(jié)8行 等于1頁(yè)。

每頁(yè)只能最多寫8行 64列，8*64 =512位 512/8 =64字節(jié)最多寫64字節(jié) 。。以上就是19264液晶屏的基本原理，雖然各個(gè)廠商硬件有所差異但原理基本相同。

以下給之前項(xiàng)目中使用的AT-C19264的驅(qū)動(dòng)部分代碼僅供參考！
