now the code is like this
| Code: | //---------------------------------------------------------
void Scroll(unsigned char row,const char *Message)
{
char Temps[30];
unsigned int MHead=0;
unsigned int Done=0;
unsigned int count;
if(row >1) row=1;
row=row*40;
while(Done==0)
{
for(count=0;count<20;count++)
{
Temps[count]=Message[MHead+count];
if(Message[MHead+count+1]==0) Done=1;
}
MHead++;
lcd_gotoxy(1,row);
lcd_putc(Temps);
Delay_ms(200);
}
}
//----------------------------------------------------- |

See my last post, I edited it.
The problem is the const keyword.
You can use
or
Both are the same but *Message is the right way to do it. |

First of all comment out the scroll(1, message); line and put
| Code: | lcd_gotoxy(0, 0);
lcd_putc('A'); |
Does it work ?
Try
| Code: | lcd_gotoxy(0, 0);
lcd_putc("Hello"); |
Does this work ?
you may need to be using
| Code: | lcd_outtext(Temps);
instead of the
lcd_putc(Temps); |
as the putc version doesn't allow for non const strings! |

Now, it is working, I have a question. How do I use this function for multiple strings? I want to have something like
| Code: |
scroll(1, text 1);
scroll (1, text 2);
scroll(1, text n); |

If they are fixed strings you just
| Code: | strcpy(message, "Message 1..................");
Scroll(1, message);
strcpy(message, "Message 2..................");
Scroll(1, message);
strcpy(message, "Message 3..................");
Scroll(1, message);
strcpy(message, "Message 4..................");
Scroll(1, message); |

Just a little bit of Googling finds it. It's here:
http://www.mydarc.de/dl3hrt/AS509-Dateien/MLX90614.C
You could translate it to CCS by substituting the lcd_gotoxy() function
for his switch-case code. You could substitute for the while() statement
with a printf() with the "%s" and 'text' as the parameters. Also,
re-direct the printf() to lcd_putc(). Also, remove the 'const' from his
function definition. It has a different meaning in CCS and isn't needed
for this function. |
