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#include <avr/io.h> /* make sure we have the UART defines */#ifndef uchar#   define  uchar   unsigned char#endif#if DEBUG_LEVEL > 0 && !(defined TXEN || defined TXEN0) /* 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 UBRR0#   define  ODDBG_UBRR  UBRR0#elif defined UBRR0L#   define  ODDBG_UBRR  UBRR0L#endif#if defined UCR#   define  ODDBG_UCR   UCR#elif defined UCSRB#   define  ODDBG_UCR   UCSRB#elif defined UCSR0B#   define  ODDBG_UCR   UCSR0B#endif#if defined TXEN#   define  ODDBG_TXEN  TXEN#else#   define  ODDBG_TXEN  TXEN0#endif#if defined USR#   define  ODDBG_USR   USR#elif defined UCSRA#   define  ODDBG_USR   UCSRA#elif defined UCSR0A#   define  ODDBG_USR   UCSR0A#endif#if defined UDRE#   define  ODDBG_UDRE  UDRE#else#   define  ODDBG_UDRE  UDRE0#endif#if defined UDR#   define  ODDBG_UDR   UDR#elif defined UDR0#   define  ODDBG_UDR   UDR0#endifstatic inline void  odDebugInit(void){    ODDBG_UCR |= (1<<ODDBG_TXEN);    ODDBG_UBRR = F_CPU / (19200 * 16L) - 1;}#else#   define odDebugInit()#endif/* ------------------------------------------------------------------------- */#endif /* __oddebug_h_included__ */
