将字模代码添加到工程中
user→gui.c→oledfont.h→cfont 16[]
在这里插入图片描述
代码实现
test.c→test.h声明一个新的函数void TEST_name(void)；
在这里插入图片描述
然后在test.c中实现

void TEST_name(void)
{
GUI_ShowString(0,16,“631807060512”,16,1);
GUI_ShowCHinese(0,32,16,“浮空花园”,1);
}

main函数

int main(void)
{
delay_init(); //延时函数初始化
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2); //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); //清屏（全黑）
while(1)
{
TEST_name();
delay_ms(1500);
delay_ms(1300);
}
}

显示效果
在这里插入图片描述
二、左右滚动长字符

代码实现
main函数

int main(void)
{
delay_init(); //延时函数初始化
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2); //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); //清屏（全黑）
while(1)
{
OLED_WR_Byte(0x2E,OLED_CMD); //关闭滚动
OLED_WR_Byte(0x27,OLED_CMD); //水平向左或者右滚动 26/27
OLED_WR_Byte(0x00,OLED_CMD); //虚拟字节
OLED_WR_Byte(0x00,OLED_CMD); //起始页 0
OLED_WR_Byte(0x07,OLED_CMD); //滚动时间间隔
OLED_WR_Byte(0x01,OLED_CMD); //终止页 1
OLED_WR_Byte(0x00,OLED_CMD); //虚拟字节
OLED_WR_Byte(0xFF,OLED_CMD); //虚拟字节
TEST_name();
OLED_WR_Byte(0x2F,OLED_CMD); //开启滚动
delay_ms(1500);
delay_ms(1350);
}
}

TEST_name

void TEST_name(void)
{
GUI_ShowCHinese(0,0,16,“重庆交大”,1);
GUI_ShowString(0,16,“631807060512”,16,1);
GUI_ShowCHinese(0,32,16,“浮空花园”,1);
}

显示效果
