MSP430F149驅動攝像模組OV7670送2.8TFT顯示（程式碼分享）

實現功能：用MSP430F149驅動OV7670攝像模組獲取圖像並緩存在FIFO中， 再把圖像送到2.8寸 TFT顯示器顯示出來， 只能實現圖像的簡單顯示， 至於白平衡， 閃光燈之類的沒有。

補充說明：●本程式部分參考互聯網。

●OV7670獲取的圖像是橫著的， 也就是320x240， 所以TFT顯示器必須橫屏顯示。

●OV7670獲取的第一幀圖像絕對是亂碼的。

●OV7670用杜邦線連到MSP430F149很容易受到干擾， 有時候動一動杜邦線可以恢復正

常， 有時綠屏了就不能恢復正常。

下進去。

●互聯網上說SIO C和SIO C兩根線需要接上拉電阻， 但是實際不接也行。
