手工办这个表，复制粘贴花了好大个老劲。贡献出来！
一个字节的点阵数，就查表得到8个16位的色彩，这里0x0000是字符背景色，0X07E0是汉字颜色，绿色。不喜欢可以改这个256*8数组。
位操作是很耗时的，这就快多了。大概时间是原来的1/8吧。

显示汉字函数在原来的基础上修改。
void LCD_DisplayChinese(uint16_t x, uint16_t y, char *pText)
{
      uint16_t  i=0,index = 0, counter = 0;       // 计数变量
  uint16_t  HZnm;       // 汉字区位码
      uint8_t disChar;       //字模的值
      uint16_t  Xaddress = x; //水平坐标

显示汉字效果与原来一样，快多了以空间换时间！

取模软件大部分是8BIT字节的，有16BIT，就好了。

没看出会快很多，反而不方便。if (disChar & 0x01)不就是剩下了一个判断和移位么。多种颜色岂不是非常麻烦了。如果要在图片上显示好像你这样就不行。

有道理，大家看看有什么更好的办法？

第一层for循环里每次循环都只从flash读一个字节，如果先把整个字形的字模读到一个缓冲区内再进for循环，应该还能更快
或者更极端点，字模的绘制操作也搞成往一个缓冲区绘制，LCD写函数放到for循环完成之后，绘制完以后只调用一次LCD写函数写入整个缓冲区，甚至还能直接DMA传过去

SPI_W25Qxx_ReadBuffer(W25Qxx_ReadBuffer,W25Qxx_TestAddr,32);
从flash一次读出32字节（一个汉字）
我考虑过先写一个汉字的缓冲区，我这个显示区也在内存中，想想就不必要了
谢谢大家关注，讨论

我先前是每行处理显示，这样与接收冲突，现在改成本次接收到的所有行一起显示，就不会与接收冲突了。

      case 0x0A:    //回车换行结尾，说明要显示字符
   if((USART_RX_BUF[usart_zz-2]==0X0D) & (USART_RX_BUF[0] != 0XFF))
   {
   if(USART_RX_BUF[0]>=0xf0)
      {HZ_XSFS=(USART_RX_BUF[0] &0x0f)+0x30;
      LCD_DisplayText(760,586,(char *)&HZ_XSFS);
      HZ_XSFS=USART_RX_BUF[0];       ////汉字显示方式设置 F0=黑底 F1=反与
}

USART_RX_TIME = HAL_GetTick(); // //字符接收停止时间=获取 systick 当前时间，单位ms
   接收中断中，有回车换行就取一个当前时间

if(((UART_HZ_Time- USART_RX_TIME) >=100)&(UART_HZ_Time>= USART_RX_TIME)) // //字符接收停止时间=获取 systick 当前时间，单位ms
   {
   LCD_DisplayNumber( 650, 586, (UART_HZ_Time- USART_RX_TIME),8); // 显示整数
   USART_RX_BUF[usart_zz] =0x00;
   usart_zz=0;
   USART_RX_TIME=0x7FFFFFFF; //设置成大数字，避免重复显示。
   LCD_DisplayTextHZ(0,0,(char *)USART_RX_BUF);//显示字符串
   LED1_OFF;
   }
主程序中判断超时，就显示处理。

你是想上位机发什么, 然后显示什么吗? 建一个缓冲区，接收和读取分开。
