为了能够看到51单片机接收到的串口数据，我选择了用oled显示收到的数据，特此花重金买了一块oled屏128X64的屏幕大概10来块钱吧！首先要达成的小目标就是能够显示数组的内容，建立一个字符数组，用来接收串口收到的数据，今天就研究怎么把数组的内容显示出来。
下面就是程序了，先来个截图，防止有些小伙伴搞不明白，我是这么走过来的，知道有朋友找到我的文章后需要的是什么？我看到的文章都不是很全，差点东西就要搞半天，我来个一次性的解决问题！
下面就是这四个文件的原码了，可以复制粘贴后直接使用！
串口_OLED.C文件，也是需要你自己来完成的文件。当然复制我的也可以实验。
cs#include"oled.h" #define uc unsigned char char str[]={0x41,0x42,0x43,0x44}; // 定义一个char类型的数组，里面放的是ABCD的十六进制数 int main() { uc *p = str; //用unsigned char类型的指针接收数组的地址 OLED_Init(); //初始化OLED OLED_Clear(); //清屏函数 while(1) { // 显示数组的值 OLED_ShowString(1,2,p,16);//第一个形参表示第六行，第二个形参表示排，第三个表示写入的字符，第四个表示字体大小 } }

好了，到此4个文件齐全了，就可以显示主函数中定义的数组char str[]={0x41,0x42,0x43,0x44};
这个数组正好是ABCD4个字符，也是我屏幕上显示的字符。
下面写怎么更改中文的数组：用字模提取软件，自己去搜索吧，不想搜索的可以关注我评论中要，给你下载链接。
最后是怎么显示中文和数字的函数使用方法，绝的帮助到你了给个免费的爱心在走吧！
cs//这个函数显示中文 OLED_ShowCHinese(0,0,0);//尚 //第一个形参是列，第二个是行，第三个是显示哪个中文，这里一个字占16宽 OLED_ShowCHinese(18,0,1);//思 OLED_ShowCHinese(36,0,2);//洁 OLED_ShowCHinese(54,0,3);//和 OLED_ShowCHinese(72,0,4);//尚 OLED_ShowCHinese(90,0,5);//思 OLED_ShowCHinese(108,0,6);//宇 //这个函数显示字符 OLED_ShowString(6,3,"shangjiulong520",16);//第一个形参表示第六行，第二个形参表示排，第三个表示写入的字符，第四个表示字体大小 OLED_ShowString(0,6,"SJL",16); OLED_ShowString(63,6,"CODE",18); //显示数字变量 OLED_ShowNum(83,6,t,1,16); //第一个参数表示列，第二个参数表示行，第三个参数表示变量数字
明天就用这堆东西来测试串口收发数据了，之前老是看不到单片机里面的数组到底是个什么样子，这下就有了参考了。
