Embedded system based wireless communication application

In this study, using 8-bit PIC16F877 microcontroller with RISC architecture, a short-range wireless communication application with RF data communications is carried out. For RF data transmission by the firm UDEA produced and making ASK modulation which ATX-34 wireless transmitter and ARX-34 wireless receiver modules are used. This application can be used in situations where short-range communications system design is difficult or costly using cable. The data read from the 6×4 keypad which is located in the transmitter section has been succesfully sent. After testing accuracy of the data received are displayed on the LCD. By the developed algorithm for wireless data transmission of data sent corruption is checked for the performance of the system. According to the experimental results, the system can be succesfully used within 30 metres.
