Micro c program rf

We can use any one or both. But it is a good practice to use both for lowering the noise coupling. Also, one thing is not mentioned in the datasheet, the variable inductor or POT at the middle of the module is used for frequency calibration.

This is a RF circuit and we need to tune the transmitter at the perfect transmitted frequency point. Also, same as the transmitter, this module also has an Antenna port; we can solder wire in coiled form for longer reception.

The transmission range is dependable on the voltage supplied to the Transmitter and the length of the antennas in both side. For this specific project we did not used external antenna and used 5V at the transmitter side. We checked with 5 meters distance and it worked perfectly.

RF Modules are very useful for long range distance wireless communication. A basic RF Transmitter and receiver circuit is shown here. We have made many projects using RF Module:. D stands for decoder which will be used in Receiver side and E stands for Encoder which will be used in Transmitter side. This ICs provide 4 channels. Also due to encoding and decoding the noise level is very low. Both ICs are identical. A0 to A7 is used for special encoding.

We can use microcontroller pins to control those pins and set configurations. The same configurations need to be matched on the other side. If both configurations are accurate and matched, we can receive data. These 8 pins can be connected to Gnd or VCC or left open. Whatever configurations we do in the encoder, we need to match the connection on the decoder. In this project we will left open those 8 pins for both encoder and decoder. For this project we did not used it.

As seen, the higher programming languages such as C enable you to solve this problem easily by writing four functions to be executed cyclically and over and over again.
