Dear all I am making RF based project.if I give pulse in transmitter side then I receive pulse in receiver side.but now I want to transfer data 1 to 99 seriely.can it be possible?here I am using 8051 microcontroller and 433mhz RF transmitter and reciever. Thanks, Tapu
i am making a wireless trigger to trigger studio flash. for this i am using 8051 controller rf module, encoder ht12e ,decoder ht12d. transmitter side: i am using encoder with at89c2051 rf transmitter receiver side: using decoder with 8051 rf receiver now the requirement is the if (...)
i am trying to design a microcontroller based fault detection system where a single receiver will receive any data from multiple transmitters. it is assumed that at a time only one transmitter will send the data. all microcontrollers belong to 8051 family, and have a 11.059MHz crystal. the baud rate is 9600bps. i have used (...)
hello, I am implementing serial half duplex communication between two 8051 micro-controllers. My circuit is like this...... 85147 > I have wrote a "C" Program for master as well as Slave. For master:> #include #include"lcd.h" #define rs P1_0 #define en P1_1 void delay(unsigned int time
hi all i want do a project that micro controller interfaced with RF modules and transmitter transmit frequency and receiver receive it, if there is any change in reviving frequency micro-controller gives signal. i want use any RF pair which is easily available in market and normal 8051 controller(not PIC, AVR) !!!! same project like RFID (...)
hi I have a problem interfacing RF module(433Mhz ask) to 8051(atmel 89C51). I am using two micro controllers First: I have written a simple program to transmit 'A' serially if P1^0 is high in transmitter micro controller(uc1). and at receiver micro controller(uc2) to take serial data and put in on P1 of (uc2
I want to interface a gas sensor to aduino board wirelessly. But it is not possible without RF. So, can I connect the sensor to RF transmitter directly and connect the RF receiver to arduino board OR I have to use a Mc(probably 8051) betn sensor and RF transmitter?? OR is there any other way(good if simpler :-P) to do it
Hello Kindly go thru the presenatition for 2.4 Ghz Rf transmitter and receiver. 8051 zigbee interface if this post is not useful ,kindly let me know the frequency of the transmissitter
i am very new to RS485. I came to know that both RS232 and RS 485 coding is same. Is it correct ! I am going to communicate 4 MCU (8051). but i am confuse with following how to send address and data. what will be H/W diagram how to program for data transfer speed .
Here I am uploading a circuit. Here pin 3,4,5,6 of 8051 are used as data inputs to L293D. But I want to use HT-12D DECODER to give the input to the L293D. Can anyone give me the circuit for it. Though irrelevant I want to tell I am using tws 434a transmitter receiver in my project.
search this forum i have already posted the sample code for 89 series controller... or visit - The Online 8051/8052 Microcontroller Resource - and you get the project there..........
everyone.i am a newcomer in the field of embedded systems.i have bought a kit for practising on 8051,avr,pic,arm,arduino and some other also has led's,7 segment display,lcd,ir receiver,ir transmitter etc.i am practising on 8051. CAN someone tell me how to make use of IR transmitter AND IR (...)
Sorry, I am not a PIC guy. IF you do it with 8051 or avr, (in assembly) I can help you. Search this forum for "Holtek" I am sure you will come up with what you need.
hello can any body tell me what to do to simulate an IR transmitter and receiver circuit with 8051 in proteus...cuz i am unable to find IR in proteus.... i know about generating pattern from another 8051 instead...but if i could use the sensor and receiver in simulation,that would be a great help..... (...)
hi i have an interest in making a robo car work as spyrobo using infrared transmitter & receiver using 8051 microcontroller. is there anyone who guide me for making remote which have 4 button for movement in forward,backward,right,left direction. explain how i modulate the infrared ray. plz........
hi i am using RF transmitter SM TX 01 and receiver SM RX 04 i have connected TXD of 8051 to transmitter module and RXD of 8051 to receiver and my program is On transmitter side -->sending 0x0f to SBUF on receiver side -->i just transfer the (...)
Hi guys, m working on a project called bus schedule indicator. in dis proj i need 2 identify d buses cuming on a particular stop. i hv 2 options for wireless data transfer i.e. bluetooth and infrared. i want 2 interface either bluetooth or infrared receiver wid microcontroller 8051 which in turn will b interfaced wid a gsm modem which ll send a ms
HI There is a fine application note at NXP site for using a microcontroller as IR transmitter & receiver For the LPC9xxx microcontroller (8051 best) The code written in C language and it is a bit easy to convert to any other micro All the best Bobi The microcontroller specialist
I tested my project Remote Data Display which involves sending characters to remote bluetooth UART module interfaced with 8051 followed by display..but failed to achieve desired result.. Now, at the receiver side m using Sparkfun's (Roving Networks) RN-41 UART module which has a default baud rate of 115.2kbps.. At the transmitter side m (...)
Hi David, I would like to apply RF transmitter & Reciver with a 8051 microcontroller as the main system design. My undestanding is you are planning to design Home Automation system.. Am i right..? If so it depends on RF Transceivers you prefer to embed with your controllers. In your case Zigbee is most suited. while choosing Zigb
