MikroC timer interrupt problem v 1.1
Hey guys i am having a serious problem.
The following program compiles successfully but when i turn on the system, there wont be be timer (caused) delay ( which can be set via some switches) after looking for long time, i figured that the timer 0 ISR is not being served. Since, I am new to MickroC compiler for 8051. Help me out!!Code:
sbit LCD_RS at P2.B0;
sbit LCD_EN at P2.B1;sbit LCD_D7 at P2.B5;
sbit LCD_D6 at P2.B4;
sbit LCD_D5 at P2.B3;

}
Lcd_Chr(1,11,((time_variable/10)+48));

I could reduce the problem as follows: Writing a subroutine (no matter which return type) with a while(1) loop, which contains an LCD command or write statement, followed by a return statement at any point in the subroutine, will reset the MCU. Removing either the while(1) loop OR the LCD command will avoid crashing the MCU. Because of that, I consider it is a bug. I typed some very simple code, which produces this bug for me on an LV24-33 v6 and PIC24FJ96GA010.
