Pic MikroC error "PC out of scope"
When I try to debug my project in Mikroc it show the error "PC out of scope".
when I comment the following line everything works fine.
error = Soft_UART_Init(&PORTC, 0, 1, 1200, 0);
Deatils:
Mcu : pic 18F4520
Xtal : 11.0592 Mhz
Here is the 8bit lcd library used in the code: View attachment __Lib_Lcd8.zip
Please help me to correct the code.
