7 segment LCM is the best choice for you , I think they have low power consumption some of them are provided with internal decoder IC and you can connect them through serial communication you can find them easily once ihave used some from
This high speed logic for 3.3V known as Low Voltage Differential Signalling LVDS or DS for short. It is a switched current sourced logic that supports 400 Mbps serial channels with very low timing skew (50ps diff.), often used for graphic data interfaces from mobile motherboard to lid lcd
hello guys , i tried to do it all my self and i have to tell u that i have a terrible headache any ways this code is to decode any remote control's signal protocol using mikroc pro and pic 16f877a and am sure there are lot of mistakes there please help me i think no body tried it before i couldnt find any info on the web :bang: RC2(ccp1) is reci
Hi All! I want to design a Caller ID Telephone with a micro-controller. The uC should built-in FSK decoder, RTC, and 40x16 segment lcd driver. Please inform me which uC to use. The uC IC should be latest; it should be in manufacturing state, not phased out. It will be better that it is SMD IC with 128 pins or smaller for better soldering. Please
I guess I am trying to understand the difference between this decoder and the one supplied within the IDE of Bascom. Maybe you are not familiar with this feature? Within Bascom select tools then lcd designer. After creating your image select OK and it places the correct code in your coding window.
i am using keypad at transmitter side and lcd at receiver . if i press 1 on key pad ,it will display on receiver side lcd . i am using encoder HT12E and decoder HT12D. i have made program but not working properly . when i press 1 it saw alpha ,for 2=ohm and wise versa . i have tested on 4 led module .means when i press 1 first led (...)
I want to interface 8870 dtmf ic with 8051 what is the program for ....this when we press 1, 2... like this thankyou Can be more specific ? You need to decode DTMF using 8051 and show number on 7-seg LED or lcd ? Interfacing 8870 DTMF decoder with 8051
I have seen many on the internet using some mp3 decoder ICs. Can the decoding be done on software (16Mhz atmega) aside with controlling a graphical lcd and keypad or pushbuttons (is the processing speed sufficient)? I would tend to agree with sky_123 that the ATMEGA would most likely not provide the required MIPS or
well thats different. You need a decoder that creates the hex value for the lcd, based on the input. How this is done will depend on the lcd datasheet. You need to read that to find out how to get characters displayed.
Hi; Have a look at here (decoding subsection), there are HW mpeg decoder IC manufacturers and their part numbers; H.264/MPEG-4 AVC products and implementations - Wikipedia, the free encyclopedia ie ST's STB7100 output MPEG video as HDMI/DVI interface. By the way todays
hey!! i am tried to decode a DTMF tone by using a decoder chip then i send it to the microcontroller at89s52 and then display the output in the lcd but when the key on the telephone set is pressed 1 only one time, the no. 1 keeps on displaying repeatedly on the lcd...how do i solve it?? plz help!!
i want to make a universal IR remote decoder with all parameter show on 16*2 lcd based on pic micro .
If you know hat a DTMF decoder is, you should be able to understand the circuit operation. You are pressing a key on the telephone dial to switch a particular relay on or off...
Hi friends, I have designed a PIC32 circuit to read images files from USB Flash Drives. Post your comments, suggestions or doubts about this (Main Board) (PIC32 Exp. Board)
2) using a encoder and decoder PC --> MCU-1 --> HT12E --> Tx (RF module) Rx(RF module) --> HT12D --> MCU2 since these encoder/decoders are 4 bit, you will probably want to send a 4 bit value (0x00 - 0x0F) rather than a letter.
hi, im doing a project based on multipurpose security system using GSM using PIR (passive infra red) sensors to detect human motion at d entrance of bank vaults etc n also an alphanumeric lcd display will be placed at the entrance so any person entering has to enter their secret password and then an sms will be sent to the administrator's mobile p
how is the keypad interfaced? e.g. via row and column digital IO pins or an SPI or similar decoder
Hi , Can any one explain how we can drive 16 lcd digits by using hef4543 IC from at89c51 controller.(each hef ic for each digit). (In one of the existing designs we checked and extracted the information that,it is driving with hef4543 IC for each between he used a 74hc4514 decoder and CD 4054). thanks and regards Amarnadh.
ok..try to find some ADC and 7 segment decoder ic..try to understant it..read the datasheet..
hi all, i need for a project to decode characters sent to RS232 Receiver module the RS 232 receiver will feed its data to the lcd display and that will be on spartan 3A . i have the RS232 Receiver module done but what i am missing is the part related to the lcd display as i want one and i hope it is in VHDL and not relying on picoblaze if
Without a schematic it's difficult to tell exactly but I would guess from the picture and the text on it that all you have to do is send it the correct sequences of signals. The decoding and driving circuits seem to be there already. Firstly, it's an LED display, not an lcd! The 2 to 4 decoder seems to be connected to transistor drivers and t
can anyone help about our code... we cant output on what we want in 7 seg Quad from MCU PIC16f877a. once the time is set in lcd it will make an output to the 7-segment quad. RA0-RA3 are for the common anode and the RC0-RC3 are the bcd-decoder. #include P16F877A.inc __config _HS_OSC & _PWRTE_OFF & _CP_OFF & _WDT_OFF & _DEBUG_OF
Hi friends, im looking for a chip dedicated for image converting to hex and hex to image. If anybody aware of this pls help me thanks in advance. VC
Hi, I'm trying to write a simple module in Verilog that I can use on an APEX APEX20K200EFC484 starter (Excalibur) board to write characters to the display. I have seen some examples here for other displays and FPGAs but finding it very difficult to get the correct information on how the display decoder works. This looks promising: www
I have a digital media player application, and I am seeking an MPU with these features built in: lcd controller for QVGA Digital picture (JPEG etc...) decoder. Encoder is NOT needed. Video decoder, must have H.264, FLV, and MPEG. Additional are preferred, for example .avi and .mov. Encoder is NOT needed. USB 2.0 MP3 (...)
Hi: How do I drive multiple 7 segment displays on a coolrunner II starter kit. I have the verilog code for the decoder module lcd(bcd,leds); input bcd; output leds; reg leds; always@(bcd) case(bcd) // 0:leds = 7'b1111110; 1:leds = 7'b0110000; 2:leds = 7'b1101101; 3:leds = 7'b1111001; default:leds
Use the 74c922 keyboard decoder chip (with interupt line)
Dot Matrix lcd Driver has RAM with Line and Column Address decoder circuit. I understand why Line & Column address block is used. But I don't know why does it have page address circuit. what is the role of page address decoder? Is it enough to have line & column address decoder if it was needed to select address? (...)
I am trying to implement a calculator which takes input via keypad or any other way like switches etc decode it into binary numbers via decoder ic perform airthmetic calculations(add,sub,mul and division only) and display the result on either 7 segments or on lcd. but so far what i hav is idea of how it should be and not any thor
we are doing a project on wireless message communicator using ATMEGA8515....we were able to interface lcd and keypad....we are using Holtek encoder HT640 and 648L decoder along with tws434a transmitter and RWS434.....but first we thought we would give some data to the encoder manually and connecting led's at the decoder end to test whether (...)

HI ALL, I AM FROM INDIA. I WANTED TO DESIGN MY OWN CALLER ID BOX. I CONSULTED MY TELEHONE SERVICE PROVIDER, WHO GAVE ME A HINT THAT HE IS USING DTMF CALLER ID SYSTEM. I DESIGNED A DTMF decoder FOR DECODING THE CALLER ID DETAILS. BUT FOR SOME REASON IT IS NOT RESPONDING:cry:.BUT THE SAME decoder CKT WORKS WELL WHEN I DIAL FROM MY TELPHONE
I do not use Morse Code reader - I read CW myself. I think that reading by microcontroller is not so reliable. But if you need circuit you can find it in QST August 1999 "A PIC16F84-Based CW decoder" . Updated software for programming the PIC16F84 and the PC-board layout diagram in Circad. :
Hello, The CLI is generated from your local telephone exchange. It is transmitted on analog lines in DTMF or FSK format. The decoder chip in the CLI device receives the signals and displays them on the lcd display. When you make a call to another telephone , your telephone exchange transmits your telephone number to the telephone exchange where
