PIC16F72编译警告求助！请高手帮忙！

只看该作者 · 2015-3-1 18:03

一直用汇编首次用PICC遇到以下问题，望请各路高手帮忙！

个人认为1，C语言基础太弱；2,对CONST不了解，3,不确定是不是FONT存储到程序段是不是要选BANK。

一、《main.c》程序：

int main(void)
{
LCDInit();

putstr(30,5,"RonView");          //这是被警告的15行
  putstr(10,1,"STC12C5A60S2");    //这是被警告的16行
  delay(30000);
cls();
  SHOW_BMP();
delay(30000);
  cls();
  LCD_write_chinese_string(0,7,12,7,0,0);
  LCD_write_chinese_string(0,5,12,7,7,0);
  LCD_write_chinese_string(0,3,12,7,14,0);
  LCD_write_chinese_string(0,1,12,7,21,0);

while(1);
}

二、其他程序片段：

const unsigned char FONT[]=             // ASCII
