Hi,
I am currently doing a project that is using IR.And I am at the transmitter part.
From what I read,there's a lot of protocol that can be used out there but we can also make our own protocol.So i decided to make my own.
One question that I would like to ask is how do you make the modulated carrier frequency to 38kHz using the microcontroller?
u can generate 38kHz freq either by using delay routines or by using timer interrupts.
if u are using RC5 protocol, then u need to embed the data bits into this 38kHz freq
