Ah yeah, ofcourse.
Thanks grumpy, I used your first suggestion and it works like a charm. I wanted a proper logic so I set the define ENABLE to 1. Makes more sense from the outside.

Thanks ye...

No, It didn't work. I tried:


#if SET_WD!=ENABLE
#undef SET_WD
#endif

Hi.

I have a Makefile with following definition:


CFLAGS += -DSET_WD=ENABLE

And in my header file, I want to have a macro funtion that determines if the SET_WD is set to ENABLE or DISABLE....

Thanks lads. That clears the mind :-)

Hi, I have a thought that i'd like to clear out.

I allocate memory say;

p = p + 5;

//do stuff

Thanks, it works!

Hi,
I want to divide a 64 bit value. I have a struct as following:

struct T
{
uint32_t high32;
uint32_t low32;
};

And in for example in my main:

I guess I have to hard code it... can't use assert function... thanks though.

Hi,

I need help on calculating sizeof through a macro. I have the folloing layout.

In file "One.h"

typedef uint16_t tTime;

And in file "Two.h" I want to calculate as follwing:

i know about the readability/maintainability. the first reason was to use only arithmetic operation is for faster execution on the target machine which is not a pc. It's an atmel processor with a...

ah yeah ofcourse... i was sitting and trying with % + / *.
thanks mike_g

Hi,
I want to make a programming procedure a bit more compact if possible:

I have the following code:


available = QUEUE_SIZE - sendQ.count;

if(available < length)
copySize = available;

Sorry. The code works. My fault. The error is a call in between... sorry for that.

Hi,

I have a little problem. I have a function as follows:


int getData(char** pStream)
{
char data[LENGTH];
...
// Addming data to the array

Thanks for the code. Looks a lot better. Regarding NesC. You're right, it is possible but only if you create an component. The reason goes in basic implementation of a nesc/tinyos design. Creating a...

Hi again,

I changed the structure to this:


typedef struct
{
word addr;
byte slot;
byte frame;

Thanks for the reply. My mistake, I got lost in the code that I forgot the obvious...

Sorry for the delay, I've been away. I'll try it now

Hi, I'm getting a crash on the routine on a device and i'm not sure why:

I have the following structures:

Hi,

I have a problem concerning time synchronization with two devices. Both devices has the following interrupt routine:



uint16_t time;
uint16_t mark;
INTERVAL = 10;
