16f84 circuit

I having problem, actually have no idea in connecting a rf circuit to a controller circuit.. anyone please help me...
 

16f84+circuit

You can use RF transceiver connected to PIC16F84. For example you can use Nordic Semiconductor (www.nvlsi.com) or Chipcon (www.chipcon.com) transceivers. On manufacturer pages you can find a lot of application with this transceivers.

What do you mean by:
connecting a rf circuit to a controller circuit

Does RF circuit have digital inputs/outputs?
 

string for 16f84

for this rf circuit it will receive data from other transmiter, and the receiving data will be used by the micro c circuit to excute the program that are burn in it. Actually i have almost zero knowledge about rf. Based on my lecture rough explaination, he said that we must have an interface circuit in order to connect rf circuit and micro c circuit. Do u have any opinion or idea about it?
 

16f84 circuit

Hello i´m from brazil
You can use mc145026 with mc145027 or mc145028 .....
4 bits encoder, decoder
Ok?!
 
transceiver with pic 16f84

U mean by using this chip i can encode or decode the data from rf circuit into micro c circuit. Thanks man for your help. I will try to look at it
 

connecting rf to pic

yes
that it´s what i mean.
it´s very good, but only 4 bits....if you want more you have do find ...may be on google
 
pic16f84a rf

if its just recieving a data pulse train via fm then you need only a diode 1n4148 and a switching transistor bc557 {or 2sc1815 etc low power silicon}

try this link in the pages the guy describes how to connect it all up but using a pic to tune then connecting the tuner to the computer

it is exactly the same process to connect a pic to the tuner instead of the computer

take a look at his project as an example here is the search string i used to find examples https://www.google.co.uk/search?hl=en&q=fm++radio++pic16f84&meta=

you could add some words like diy ++ project ++ schematic --

also try looking for packet radio links and on the amature radio retworks
and schematic ftps

Hi
Could you tell us what is the output of your RF circuit that you need to connect to the PIC. You should tell us about the interface specification to be able to help u.

For example
Interface type : serial or paralle
Data rate ??
voltage levels ??
any other data that you think it is useful

Thanks
Haytham
 

16f84 train

Interface type : serial port
Data rate and and volatge level are determined yet coz it still under research. I also have less knowledge about this.
For this part the rf circuit will operates as a receiver to receive data and will sending these data to the micro c circuit to control the home appliance. Is there anything else that U need to know?
 

Hi
If you mean that your RF circuit has a serial interface, then it is wuld be easy to interface it to any MC.
Also, data rate if you mean by serial port the UART protocol, thenit would be also has its max. data rate defined by the UART standard.

Voltage levels if you want to intrface to MC should be digtal levels.

I think that you should work more to define precisly your interface spcifications

Thanks
