So, I need to communicate wirelessly between a micro-controller and my computer. I'm building a radio receiver circuit, and a radio transmitter circuit that works on FM transmission. However, I had an idea.
I'm just transmitting binary. The receiver will go into the micro-controller's UART lane. If I'm transmitting serial data, wouldn't it be easier to simply transmit a specific un-modulated frequency that represents a one, then design the circuit to accept no radio transmission as a zero?
Then the micro-controller program could simply seek out combinations of one's and zeros that it recognized as bytes?
Is there a downside to this that I'm not thinking about? Is there already a name for this kind of rf data transmission?
