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。

#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！

//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。
