hello frnds,
i want to send data using a IR from PIC microcontroller.. which encoder/decoder is suitable for this application? if im using ht12E/HT12A/ht12D/ HT640/HT648.. what should be the r osc value( oscillator) .. can any one post a working circuit diagram to transmit data..
Thanks in...
i got a solution for the scrolling message with PIC6F877 and 5x7 led matrix..
nw im working to scroll message in four,5x7 matrix ,,
code is written in MPlab IDE and simulated in proteus
here im attaching my work..
thanks a lot to everyone
Thank u for ur response .. clock is defined for the pin PIN_B0.. i coudnt work shift register with pic. the out puts are orderless.. if u hav any schematic n code , can u post it.. i want to scroll a text from right to left using four, 5x7 led matrix with help of PIC 16F877. i know only C...
i tried to implement a ckt to scroll message as tutorial in proteus and Mikroc. i failed to obtain a output .. any one can post a working schematic with PIC16F877 and 5x7 matrix led with c code.. Thanks in advance
Thank u for ur replay.. i need extra button to control TE pin.. otherwise i should connect a high signal to it.. if i connect high to TE the IR LED always glowing...
Thanking yOu

Sir, how can i plot a graph in vb.net from the serial port.. i have connected a pic micro controller to pc.. the micro controller is sending ADC values to PC.. i want to plot it as graph.. i tried to plot a sine wave from function generator in matlab.. its working fine.. i want to replace matlab...
Thank u sir,
i tried with Ht series .. it has transmit enable pin.. it should b high for transmission.. so i need a extra microcontroller to operate.. i dont want a microcontroller in my circuit.. how to design a remote control system with out a microcontroller.
Thanking You

sir,
I want to control 5 relays using a ir remote control.. how to design a ir transmitter and receiver for this purpose... can i avoid a microcontroller in both transmitter and receiving side.. which encoder / decoder is suitable for my application...
Pls help me to design such system...
SIR,
i got some assemble code for 8051.. im a beginner in pic and i know only c with mplap ide.. can u help to decode rc5 using pic with c code..
Thanks
