Hello. I have problem. I'm using v4.103 for PIC24fj64ga002. And my problem:
| Code: |
float result;
printf(lcd_putc, "%f",result);
|
It's some part of my code. When my program come to line
| Code: |
printf(lcd_putc, "%f",result);
|
and try do it then PIC is RESET. What I don't do right ? I use this function for PIC16f877A and don't have any problem. Please help me.
You will excuse me for the rough language. I am from the Ukraine. |

I can imagine at least two possible problems:
- any issues with your implemenation of lcd_putc(), e.g. involving access to non-existent memory. Does lcd_putc() work with other data types?
-a stack overflow, as dicussed in the forum before. Try to increase the stack by
| Code: | | #build(stack = 256) |

| Could also be WDT. Show your fuses and init code. |

| Seems like CCS developers will be the last to realize, that PCD default stack allocation is insufficient. |
