Micro-controller wioth RF module:

[karan123]

Hi,

I want to interface Simple RF ASK Module with Micro controller at both Receiver and transmitter side for sending Data.

Can any body guide me, Data in and Data out connected to which pin of micro controller?

I don't want to chose HT12D/HT12E decoder.

Here is a page which can give you a idea

Thanks for link

But I don't want to chose HT12D/HT12E decoder.

You need to send serial data to the Tx and the same will be delivered out of the module RX. Thaz it. In your case just replace the HT12 with micro and program the same to do the task. Cheers

It is advised to use manchester encoding to get proper results. If you dont want to use ht chips, you can do it in the micro itself

Hi,

how to implement that?

I don't have any idea about manchester encoding ?

Any Example Code?

Hi,

I can you 8051 with Keil or

PIC18F4520 with MPLAB C18

You will never find sample source code. These cheap modules (specifically the receiver module) don't work when connected directly to an 89C51. (read the spec sheets for the MCU and the receiver) I chose to do it with an avr instead.

Read my post in the above link. It may give you some ideas on how to accomplish this task.

Good Luck

Use the serial port of the microcontroller with the TX/RX module, but make sure the baud rate is below 500.
Baud rate with 300 works fine for me. Check out this project https://www.8051projects.info/proj.asp?ID=49
