Transmitting Pronto codes

[sanddune008]

Hi All,

I am using an IR transmitter using the Pronto coding scheme....

Details Obtained from following link:

RC: The Pronto's IR Code Format (2)

coming to the problem:
Do I have to sent Preamble.....along with each command if so how?.........

Since there is no burst pair sequence to represent the preamble.......

Thanks in advance......
