4、通過改變字符顯示函數(shù)的第二個參數(shù)來改變亮度和暗度(9)如何使顯示的圖形變寬？變窄？變高？變矮？答：通過改變顯示圖形函數(shù) RIT128x96x4ImageDraw(buf, 18, 84, 162, 1)中的第 三個數(shù)，可變寬變窄，最后一個數(shù)，改變高瘦。(10)漢字如何顯示？答：可用顯示圖形的方法進行字符拼接。二、實驗?zāi)康暮托Ч?效果即是否達到實驗?zāi)康?，達到的程度如何)目的：(1)初步學(xué)習(xí)、理解、掌握 OLED字符顯示方法(2)初步學(xué)習(xí)、理解、掌握 OLED圖形顯示方法效果：(1)在OLED屏幕上分行顯示自己的學(xué)號、姓名、項目序號、時間，(2) 在OLED屏幕上顯示一條橫線和豎線。(3)在OLE

5、D屏幕上顯示三個5*7比例的字符圖形(大、中、小各一個)，每位同學(xué)根據(jù)附錄1分配表查找自己應(yīng)該顯示的字符，每個字符顯示效果見附錄2。(4)擴展：在OLED屏幕上畫一個型圖案。(5)擴展：在OLED屏幕上畫出自己的“姓”或“名”圖案。三、實驗內(nèi)容和步驟(重點闡述自己的思路及遇到的問題)(一)建立項目(1)首先新建一個project(2)選擇 CPU 本實驗選 Luminary LM3S 8962(3)加載庫文件(4)項目相關(guān)配置項修改（二）嵌入式C 程序開發(fā)（1）加載必要程序：本次實驗提供了幾個源程序 rit128x96x4.h ， rit128x96x4.c ，startup.s 并且將這幾個

6、文件復(fù)制到項目工作目錄中。（ 2）新建主函數(shù)程序，并加載到項目中（ 3）開發(fā)主函數(shù)，完成基本顯示功能（信息提示與直線）頭文件有以下三個#include #include #include rit128x96x4.h（ 4）開發(fā)主函數(shù)，完成拼接字符顯示功能（ 5）編譯、連接，生成可執(zhí)行程序文件（ 6）反復(fù)（3） -（ 4）步驟，直到完成（三）硬件連接（ 1） 接上電源線， 先關(guān)閉開關(guān)（ 2） 用藍色 USB 線接上仿真器， 仿真器另一JTAG端接 LM3S8962 CPU 板（左下較大子板）， USB 線接電腦（ 3）確認連接無誤后，打開電源開關(guān)（四）聯(lián)調(diào)（ 1）在 Keil uVision4

7、中執(zhí)行下載，（ Flash 菜單 -Download ），即可通過仿真器將（一）步編譯鏈接好的執(zhí)行程序下載到 LM3S8962 芯片內(nèi)的 Flash 中。（2）按下實驗箱上LM3s8962子板屏幕上方的白色按鈕Reset鍵，即可查看程序執(zhí)行效果。若有問題，返回第一步繼續(xù)修改程序，編譯、鏈接、下載，一直到顯示出滿意的效果。實驗代碼： 1）#include #include #include rit128x96x4.hunsigned char buf1 = 0x00,0x00, 0xff,0xff, 0xff,0xff, 0xff,0xff, 0x00,0x00, ;unsigned char
