• 51单片机用IIc控制OLED显示数组内容

    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。

    1. #include"oled.h"
    2. #define uc unsigned char
    3. 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
    4.  
    5. int main()
    6. {	
    7. 	uc *p = str;     //用unsigned char类型的指针接收数组的地址
    8. 	OLED_Init();			//初始化OLED  
    9. 	
    10. 	OLED_Clear(); 		//清屏函数
    11. 	
    12. 	while(1)
    13. 	{
    14. 		// 显示数组的值
    15. 		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
    16. 	}	
    17. }

    oled.c文件，关于oled中所需要的函数尽数在这里：

    2. #include "oledfont.h"  	//取模的中文库

    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！

    1. //这个函数显示中文
    2. 		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
    3. 		OLED_ShowCHinese(18,0,1);//思
