Debugging can be configured with the define'DEBUG_LEVEL'. If this macro is not defined or defined to 0, all debuggingcalls are no-ops. If it is 1, DBG1 logs will appear, but not DBG2. If it is2, DBG1 and DBG2 logs will be printed.A debug log consists of a label ('prefix') to indicate which debug log createdthe output and a memory block to dump in hex ('data' and 'len').*/#ifndef F_CPU#	define	F_CPU	12000000	/* 12 MHz */#endif#ifndef uchar#	define	uchar	unsigned char#endif#if DEBUG_LEVEL > 0 && !defined TXEN	/* no UART in device */#	warning "Debugging disabled because device has no UART"#	undef	DEBUG_LEVEL#endif#ifndef DEBUG_LEVEL#	define	DEBUG_LEVEL	0#endif/* ------------------------------------------------------------------------- */#if DEBUG_LEVEL > 0#	define	DBG1(prefix, data, len)	odDebug(prefix, data, len)#else#	define	DBG1(prefix, data, len)#endif#if DEBUG_LEVEL > 1#	define	DBG2(prefix, data, len)	odDebug(prefix, data, len)#else#	define	DBG2(prefix, data, len)#endif/* ------------------------------------------------------------------------- */#if	DEBUG_LEVEL > 0extern void	odDebug(uchar prefix, uchar *data, uchar len);/* Try to find our control registers; ATMEL likes to rename these */#if defined UBRR#	define	ODDBG_UBRR	UBRR#elif defined UBRRL#	define	ODDBG_UBRR	UBRRL#elif defined UBRR1#	define	ODDBG_UBRR	UBRR1#elif defined UBRR1L#	define	ODDBG_UBRR	UBRR1L#endif#if defined UCR#	define	ODDBG_UCR	UCR#elif defined UCSRB#	define	ODDBG_UCR	UCSRB#elif defined UCSR1B#	define	ODDBG_UCR	UCSR1B#endif#if defined	USR#	define	ODDBG_USR	USR#elif defined UCSRA#	define	ODDBG_USR	UCSRA#elif defined UCSR1A#	define	ODDBG_USR	UCSR1A#endif#if defined UDR#	define	ODDBG_UDR	UDR#elif defined UDR1#	define	ODDBG_UDR	UDR1#endifstatic inline void	odDebugInit(void){	ODDBG_UCR |= (1<<TXEN);	ODDBG_UBRR = F_CPU / (19200 * 16L) - 1;}#else#	define odDebugInit()#endif/* ------------------------------------------------------------------------- */#endif /* __oddebug_h_included__ */
