Hi all, I'm working on a scheme to send data from one module to another. The parts i'm using are a HT12E + TX433, with 1 Mohm resistor for the transmitter and Ht12D + RX433, with 47K resistor. (followed the velleman scheme) I'm using a microcontroller to drive the transmitter. The code is:
te=1
a=1
b=1
c=1
d=1
te=0
waitms 500
te=1
a=0
b=0
c=0
d=0
te=0
nothing wrong with that. I can see the Ht12E transmitting.
on the other side there 'm receiving information on the data in-pin. The VE-pin is changing on the fluctuating signal. This works great. But my dataoutput pins are giving a low outputsignal (10mV). I guessed this would have something to do with noise and uppered the resistor on the HT12D to get a higher frequency, but then I get no output signal. Any suggestions?
