Hi,
I am interfacing a 433 MHz transmitter receiver pair with PIC 16F73 using the serial port.
I have connected the transmitter to another PIC.
The transmitter PIC sends data serially, continuously, at baud rate 2400.
I can receive the data with the receiver module. I can see the data stream in a scope, whose output is TTL.
But when I connect it (the RX output) to the RX pin of PIC, the amplitude drops to 2V and an offset of 1V appears on the scope. I cant receive the data serially.
But if I connect the two PICs with wires, the serial port works well and fine.
Is it a problem with my RF receiver or do I have to add something else to the circuit??
Thanks!!
