stm32f103c8t6與ili9325液晶

我想用stm32f103c8t6點亮ili9325液晶 程序如下
但是畫面全白 並沒有變成紅色
想請教各位大大該如何修改? 謝謝
另外算了一下 320*240*2 = 150k
stm32f103c8t6的flash只有64k
所以就算想存一張圖片開機顯示也沒辨法
不知我這樣想對嗎? 謝謝

这个需要看完程序才能下结论啊

感謝回答 後來發現有兩條線接錯現在有畫面了 謝謝

ili9325自带显存 足够显示一副图片，不需要用stm32的flsah，你多虑了。

你好 我不太了解你的意思
因為我只能透過jlink寫程序到mcu
再由mcu寫命令和資料到lcd
就算ili9325有顯存 我要如何一開始就把圖形存在裡面?
謝謝

我理解错了，如果是这样你确实需要一块片外的rom。ili9325显存是ram类型。

你好 感謝解答
