Detailed Description

System wide Definitions for FREMO Clock.

System wide Definitions to get all those things to one place, which are suspect to change very often; e.g. Baudrate, Frequency of Oscillator, MCU-Type or Board.

Target:

• any AVR device with output compare on timer0

Software

• AVR-GCC with WinAVR

#define DEBUG_TIMER_ON

Do not know what this is used for.

Definition at line 87 of file sysdef.h.

#define F_CPU   16000000

Processor frequency.

This may also be predefined in Makefile of by eclipse avr plugin.16 MHz

Definition at line 67 of file sysdef.h.

MCU is defined in the makefile (or eclipse avr plugin) and passed to compiler by -mmcu switch. It can be accessed by code like:

#if defined (__AVR_ATmega168__)

Definition at line 56 of file sysdef.h.

#define SYSTEM_TIMER_ON

Definition at line 89 of file sysdef.h.

#define VERSION   "1.3A01"

Version String of software package.

Something like "1.2A01".
