Publish your circuit diagram here....i need to see how did you connected the ASK module and the controller... State the voltage in all the points in circuit....
sorry but i haven finished up the circuit diagram
i give you the explanation of it(Sorry)
i am using 16f877a for both transmitting ans recieving,
for the transmitter side
i connect directly to the data of the transmitter ans portc pin 6 of the mcu
ground of transmitter to common ground
vcc to 5vdc (roughly 4.86v)
ant of transmitter to a 30cm long antenna
for the receiving side
i connect directly to the 2 data line of the receiver unit and portc pin 7 of the mcu
the ground line all to common ground
the vcc all to 5vdc (roughly 4.86v)
ant of receiver to 30 cm long anntenna
i am using usb power by laptop 5vdc
by only using serial line, i can transmit and recieve but when come to connecting the module , its never work,
thanks for the help
