If you want to add time log in the code ...

PBSearchingTimeMS = \

(unsigned long)((PBSearchingTimeTickEnd - PBSearchingTimeTickStart) / 32.768);

* change clock (frequency) to time: 32.768 (Crystal Clock)

Custom Token Macro in Source Insight

We suppose,

When you use the "Source Insight" as your source code editor,

Source code is as followed

 #define PACKED __packed

 typedef PACKED struct {

  int age;

  int tall;

 } MyStyleType;

Source Insight cannot parsing the variable "MyStyleType".

How can you fix it?

Source Insight support "*.tom" file.

In this case, we can change or add "c.tom"

c.tom file in the MyDocument\Source Insight\C.tom

We can add some key words,

_packed

packed

PACKED

That's all.

How to define "printf(...)" to "DEBUG(...)" in C/C++

When you make a program or programs, you need to check the program running condition.

In this reason, you want to use the debug message into the program.

In the debugging time you use the print put the logging messages and in the release time you don't want to use the logging messages.

When you use the macro "#define" how can you convert printf(char* format, ...) function to macro function?

As following,

// Multiple arguments

#define MSG_ERR(format, ...)    TRACE(ERROR, format, __VA_ARGS__)

#define MSG_WARN(format, ...)   TRACE(WARNING, format, __VA_ARGS__)

#define MSG_HIGH(format, ...)   TRACE(HIGH, format, __VA_ARGS__)

#define MSG_MID(format, ...)    TRACE(MIDDLE, format, __VA_ARGS__)

#define MSG_LOW(format, ...)    TRACE(LOW, format, __VA_ARGS__)

// Single argument

#define MSG_ERR(format)        TRACE(ERROR, format)

#define MSG_WARN(format)       TRACE(WARNING, format)

#define MSG_HIGH(format)       TRACE(HIGH, format)

#define MSG_MID(format)        TRACE(MIDDLE, format)

#define MSG_LOW(format)        TRACE(LOW, format)

Support for variadic macros was introduced in Visual C++ 2005.

About Bit Field in C/C++

In the C/C++, 

usually we use the "Bit Field" to optimize code or communicate with other process.

What is the Bit Filed?

I have attached "Example Code".

Example code

// Test Code, Bit Field

// ----------------------------------

{

 #define u8 unsigned char

 #define FILL_STRUCT1 u8:0; u8:8; u8:0;

 #define FILL_STRUCT2 u8:0; u8:8; u8:8; u8:0;

 #define FILL_STRUCT3 u8:0; u8:8; u8:8; u8:8; u8:0;

 typedef struct tag_SIMCommand {

 u8 Class;

 u8 Instruction;

 u8 P1;

 u8 P2;

 u8 P3;

 FILL_STRUCT3 // Bit Field

 u8 CData[8];

 } SIMCommandType;

 SIMCommandType SIMCommand;

 memset(&SIMCommand, 0xFF, sizeof(SIMCommandType));

 memset(&SIMCommand, 0x00, sizeof(SIMCommandType));

 // SELECT

 SIMCommand.Class = 0xA0;

 SIMCommand.Instruction = 0xA4;

 SIMCommand.P1 = 0x00;

 SIMCommand.P2 = 0x00;

 SIMCommand.P3 = 0x02;

 memset(SIMCommand.CData, 0xFF, sizeof(u8)*8);

Soap opera, TV Drama?

Nowadays I am watching TV series

Grey's Anatomy: Season 1, 2, 3, 4, and 5

 now, I am watching season 2.

Previous time, I watched

LOST: Season 1, 2, 3, 4, and 5

 I already watched season 1, 2, and 3.

HEROES: Season 1, 2, and 3

 I already watched season 1, 2.

Previous time, I have watched 24, Numb3rs, ... 

When I was school student, I have watched many Americana's TV series,

for example MacGyver, Air Wolf, The Wonder Years and so on.

In the future, can I watch these TV series without caption?

Do you have a dream or a plan?

In the computer algorithm, there is "Divide and Conquer" i.e. when you solve the problem divide the problems and solve each of them. 

Today is the first working day of this year 2009.

Now, I am making this year's decision.

1. Increase family member.

2. Read English written books more than 10.

3. Join the on line lessons more than 10.

4. Upload blog more than 10 every month.

And end of this year, I will check them.

Let's start!

January 2nd, 2009.
