The 8051 Friendly board is specifically designed to help students to master the required skills in the area of embedded systems. The kit is designed in such way that all the possible features of the microcontroller will be easily used by the students. The kit supports in system programming (ISP) which is done through serial port.
NXP’s 8051 (AT89V51RD2), 8051 Friendly Kit is proposed to smooth the progress of developing and debugging of various designs encompassing of speed 8-bit Microcontrollers.
Radio Frequency, any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation.
RF433.92MHz transmitter Module conneted with 4-bit encoder, user can evaluated RF interface in two ways (Standalone without MCU, user can give inputs through 4-way DIP switchSW35) while making switch SW35 to ON positions inputs low goes to the encoder. Data will transmit through the module. Also provided to configure address lines of the encoder.
RF433.92MHz Receiver Module connected with 4-bit decoder, user can evaluated RF signal with the help of LED indications. Whenever receives data through transmitter VT LED, indicates for valid transmission.
The Interfacing RF with 8051 program is very simple and straight forward that uses a transmitting and receiving data. In C programs you cannot be sure of delay, because it depends on compiler how it optimizes the loops as soon as you make changes in the options the delay changes.
