lcd does not show the first char of the converted string
PostPosted: Sun Jan 03, 2010 10:13 am     Reply with quote
Here is my codes. I get the string from serial channel and show it on 1st line of the LCD. It is ok. But when I try to convert it by using atol() then the first char is not shown. Could you help me?
Code:

char gv[10]=""; 
char gv2[10]="";
 
#int_RDA
RDA_isr()
{
disable_interrupts(int_rda);
gets(gv);

z=atol(gv);
lcd_gotoxy(1,2);
printf(lcd_putc,"gveri:%s",gv);
lcd_gotoxy(1,1);
printf(lcd_putc,"%lu",z);
}



//////////////the summary is below
023
gveri:123

any comment?

See this thread for more comments about what code should be put in
an #int_rda routine (and what code you should not put in it):
