accessing bitwise data in a data buffer

"Undoubtedly, some timing requirements must be added..."

Indeed, and/or some clock signalling requirements.

Hi ALL,

You can make use of mask to send bitwise onto a port.
Take a look at this:
sending LSB to MSB

temp = 0x01;
for(i=0;i<8;i++)
{
if(temp == (temp & byteTObeSent))
{
DATAPIN = 1;
}
else
DATAPIN = 0;
temp <<=1;
}

Think logically and code logically.

The earlier post has function code to send 1 byte.
Now include a for loop for number of bytes and send each byte to this function.

Yes, indeed it requires timing.

hi all,

thanks for the overwhelming response that i received for my question. i have written the code for sending bit by bit data on a single pin of port 0 with reference to a clock.
i thank one and all for the response
cheers,

Seems over-complicated to me:
Why not just shift the 32-bit number, mask the LSB, and send it direct?

for( i=0; i<32; i++ )
{
   DATAPIN = wordToSend & 1;
   wordToSend >>= 1;
}

HI,
ofcourse that works for 32 bits and will occupy less instructions.
I was considering a generic function which can send a byte. Depending on his size he may call this function accordingly.

"I was considering a generic function which can send a byte."

Even more reason to keep it simple:

for( i=0; i<8; i++ )
{
   DATAPIN = byteToSend & 1;
   byteToSend >>= 1;
}
