Compiler error using AVR Atmel Studio library config files

#ifndef UART_UART_CFG_H
#define UART_UART_CFG_H

#define UART_BaudRate     1200   //9600UL
#define CLK               16
#define UART_Parity       NONE
#define UART_TX           EN_TX
#define UART_RX           EN_RX
#define UART_STARTBITS      1
#define UART_STOPBITS       1
#define UART_DATABITS   EightBits

#endif //UART_UART_CFG_H

This is the error "called object is not a function or pointer" and this my private file that have all word's addresses inside the config file. The first file:

#define DIS         0  // Disable
#define EN          1  // Enable

#define UART_9600   9600UL
#endif //UART_UART_PRIV_H

Private file that have some addresses for my Microcontroller ATmega16. Moreover, my config file is reference to private file; which have keys that defined in private. For example, in UART_Partit I wrote NONE and NONE address defined in private but it shows error

Answer 1

You need to include your file with declarations.

#ifndef UART_UART_CFG_H
#define UART_UART_CFG_H

#include "uart_priv.h"

#define UART_BaudRate     1200   //9600UL
#define CLK               16
#define UART_Parity       NONE
#define UART_TX           EN_TX
#define UART_RX           EN_RX
#define UART_STARTBITS      1
#define UART_STOPBITS       1
#define UART_DATABITS   EightBits

#endif //UART_UART_CFG_H

and there are no EN_TX or EN_RX defines for these constants in your second file.
