Hey I was just wondering if this is what you meant. This is what I tried but the same thing is happening. It prints the first line and then it constantky flashes printing the next word on top of the first word.

sbit busy = 0x087; //busy bit = db7

void chkbusy(void)
{
data unsigned temp;
do{
LCD_EN = 1; // CLOCKS E HIGH
temp = LCD_DATA;
LCD_EN = 0; // CLOCKS E LOW
} while (temp & 0x80);
}
