單片機顯示圖形程序

❶ 51單片機顯示時間的流程圖怎麼畫

51單片機顯示時間的流程圖畫步驟。
1、首先畫出51單片機流程圖框架。
2、其次添加流程圖細節，完善框架。最後寫上文字標題即可畫出單片機顯示時間的流程圖。51單片機是對所有兼容Intel8031指令系統的單片機的統稱。

❸ 單片機的課程設計——在8*8點陣顯示圖形

這個問題不是很難！
我的理解是樓主可能只用單片機和點陣模塊來實現，這需要單片現來做動態掃描。
首先需要你把點陣上要顯示圖形的代碼寫出來，即每種圖形每行顯示的數據，每個圖形有8行數據，即佔8個位元組的空間！
如果樓主用51單片機來實現的話，可以使用P0口輸出行數據，P1口作為點陣的行掃描控制。
其次要用按鍵控制，只需你把每種圖形以不同的表存起來，再做一個按鍵掃描程序，當檢測到有鍵按下時，把動態掃描的表頭地址更換即可！

❹ 單片機，寫了一個12864lcd（帶字型檔）的圖片顯示程序，但是實現不了，求幫助

你要顯示的是圖片的話，就要用到擴充指令，lcd_init是基本指令，
write_cmd(0x36);
write_cmd(0x3E);
write_cmd(0x01);
還有你display_bmp（）程序中下半屏的循環顯示碼錯字了
for(i=0;i<0;i++)應該是
for(i=0;i<32;i++)
