一、下载资料包
下载解压之后打开文件夹中的Demo，然后选择相应的板子Demo，用Keil编译
将程序烧录到开发板并运行
?二、修改程序显示学号和姓名
找到姓名的中文点阵
显示函数
void TEST_MainPage(void)
{
GUI_ShowCHinese(28,20,16,"刘蒙",1);//中文姓名
GUI_ShowString(4,48,"631907060512",16,1);//数字详细
delay_ms(1500);
delay_ms(1500);
}
main函数
int main(void)
{
delay_init(); //延时函数初始化
OLED_Init(); //初始化OLED
OLED_Clear(0); //清屏（全黑）
while(1)
{
TEST_MainPage(); //界面显示
}
}
结果如下
温湿度显示
在之前温湿度代码中添加OLED代码
修改main.c文件
#include "delay.h"
#include "usart.h"
#include "bsp_i2c.h"
#include "sys.h"
#include "oled.h"
#include "gui.h"
#include "test.h"
int main(void)
{
delay_init(); //延时函数初始化
uart_init(115200);
IIC_Init();
NVIC_Configuration(); //设置NVIC中断分组2:2位抢占优先级，2位响应优先级
OLED_Init(); //初始化OLED
OLED_Clear(0);
while(1)
{
//printf("温度湿度显示");
read_AHT20_once();
OLED_Clear(0);
delay_ms(1500);
}
}
修改bsp_i2c.c文件中的read_AHT20函数如下：
void read_AHT20(void)
{
uint8_t i;
for(i=0; i<6; i++)
{
readByte[i]=0;
}
//-------------
I2C_Start();
I2C_WriteByte(0x71);
ack_status = Receive_ACK();
readByte[0]= I2C_ReadByte();
Send_ACK();
readByte[1]= I2C_ReadByte();
Send_ACK();
readByte[2]= I2C_ReadByte();
Send_ACK();
readByte[3]= I2C_ReadByte();
Send_ACK();
readByte[4]= I2C_ReadByte();
Send_ACK();
readByte[5]= I2C_ReadByte();
SendNot_Ack();
//Send_ACK();
I2C_Stop();
//--------------

H1 = (H1*1000)/1024/1024;
T1 = readByte[3];
T1 = T1 & 0x0000000F;
T1 = (T1<<8) | readByte[4];
T1 = (T1<<8) | readByte[5];
T1 = (T1*2000)/1024/1024 - 500;
AHT20_OutData[0] = (H1>>8) & 0x000000FF;
AHT20_OutData[1] = H1 & 0x000000FF;
AHT20_OutData[2] = (T1>>8) & 0x000000FF;
AHT20_OutData[3] = T1 & 0x000000FF;
}
else
{
AHT20_OutData[0] = 0xFF;
AHT20_OutData[1] = 0xFF;
AHT20_OutData[2] = 0xFF;
AHT20_OutData[3] = 0xFF;
printf("lyy");
}
printf("\r\n");
printf("温度:%d%d.%d",T1/100,(T1/10)%10,T1%10);
printf("湿度:%d%d.%d",H1/100,(H1/10)%10,H1%10);

//printf(strTemp);
//printf("/r/n");
