Remote 8051

Hi! I'm not sure I have completely understood what you mean by "i have success in detecting pulses but counting and changes with respect to numbers." But let's have this straight: First of all, you may know that IR protocol frequency may vary from 38 to 42 KHz. The IR protocol varies slightly with every manufacturer, but tends to be like the jap

Hi Im Trying To Build An NEC Decoder. I Connected A TSOP1738 To Interrupt 0 Pin (P3.2) Of 8051. To Make The Port as An Input I Made it High TSOP1738 Too Is In High Normally And Goes Low When It Receives IR Pulse. Any How The P3.2 Remains Always High. How Can I Detect Incoming Of Pulse. Bit Confusing To Me Can Anybody Help. (Hope Am Clear A

Hi good evening everybody... I have circuit and i want to change some connection in this circuit....... My recomedation is as follows When the Dispaly is 0, only the LED 1 ON When the Dispaly is 1, the LED 1 and 2 ON When the Dispaly is 2, the LED 1,2 and 3 ON When the Dispaly is 3, the LED 1,2,3 and 4 ON When the Dispaly is 4, the LED 1

Dear All Expert, I need a ultra low power microcontroller to be used in a alkaline AAA 3V battery operated wireless remote controller. I need it to shut down at all time until a certain pushbutton is pressed. I also need it to had a inbuild wireless transmitter that is Zigbee compliance, as I need to send AT

hello friends. im trying to make a ir remote controle for some operations. i just want to enable and disable port pins while pressing the button in remote. im using rc5 protocol. it is transmitting 14 bits. i dont know how to decode that in 8051. pls help me out with this. should i have to give the received bits in timer interupt or in (...)

actually i want to control a stepper motor with infrared remote. im using HT6221 Multi-Purpose Encoders IC... from this IC for each button press its transmitting 7 bit of binary values through infrared. my doubt is in receiver section that means in microcontroller where i have to connect the receiver IR and how to program it?? can i connect that IR

Hi! I'm making a project with microcontroller 8051 connecting to ISD4002 chipcorder. the project including remote control using NEC protocol, ISD4002 chip with speaker and microphone, all connected and manage by the 8051. (nxp p89v51rd2). my problem is that when i'm sending the spi code to the 4002 of recording or playing it's generate (...)

hi, i am developing remote control of "COMTECH CDM550 SATELLITE MODEM". this modem is controlled by RS232 communication. now i am using 8051 mocrocontroller for controllling that hardware. but the problem is that i have developed code for sending command via serial communication. when i connect my remote control to hyper terminal of my (...)

I'm working on a project about remote controlled house (home automation). This is for my capstone project which I'm working on.:smile: I want to send SMS messages from my mobile phone to a Telit GM862 GSM device and those messages need to pass throw UART to a 8051 microcontroller (Atmel AT89S8253). The microcontroller needs to understand them as
