Hi, I am using PIC 16f873A controller. I that project I want to display float value in 4 digit seven segment LED display. the data lines(a to g) of the seven segment display is port B1 to B7, and dot point (DP) at C0. Can anybody help for me? Thanks in advance. (...)
first let me clear your question..there is no 6 SSD . SSD is seven segment display. you can built A circuit with 5 volt supply and if u know binary code in the scene that is more than enough to write the code. you need 470ohm of pull up array to connect to the seven segment.use 8051 any port i think below (...)

Hi, I have to implement a thermometer. I use on my project a PIC18F2620, a LM35, and the temperature is displayed on 3 seven segment display. In order to have a stable display, I use the Timer0, and I read the value of temperature at each 1 sec. The problem is the fact that there is nothing (...)
hii i am trying to interface a seven segment led display of four digit (common cathod) with the msp4302112.can any one tell me how i can interface ?
How can I dispaly in a seven segment dispaly, with a atmel mega16 , several resistor and swithches, the numbers of 0 to 9, if a use the switches as a input for numbers in binary code, how can i read the 1 or 0 they send to me , in which register they will be located.
I am a beginner of learning hoe to use PIC to display seven segment display. Can anyone give a suggestion how to do. I am using MPLab IDE v7.31.
This condition refers to dynamic displaying. the display step is like this: 1. for one time, you can select one seven segment, and put your digit to it, then wait for a moment (< 0.1/4 s) 2.and then, you can select another seven segment, and do the same thing as the first one. 3. repeat (...)
Hi friends, I have planned to design aa digital clock using large seven segment display, can any one help me in this.
I want to drive 4" seven segment display (25 nos.) 5 X 5 matrix form. But I do not know how to drive 4" seven seg display . Please suggest any driver IC also Latch for that. CD4511 But, you can control 4 sev. seg displays without using any driver/latch ICs, by using multiplexing (...)

Hi dudes, i am trying to display four seven segment s on the board. I know the code to enable one seven segment display. But four at a has to change. Can any one will support for me. I am using DE0 kit from altera. Thanks in advance.
Hello, Though I'm a newbie at VHDL I managed to write a keyboard interface ( though it is only unidirectional, it is a success) for my board and am correctly displaying the letters on SSD. Now I am thinking of going one step further, that is to say I want to extend the borders of SSD. But I can not think of any simple way to do so, I need some a

hai, i am doing my project,please help me in writing a program in both assembly language and in c language to continuously run microcontroller 8051 as a timer in seconds and display time in seconds using 4 digit seven segment display so that it can view from 0 to 9999 seconds. please.....
hello genius guys well now i am making a XCESS-3 calculator .the only problem i am facing is HOW TO DRIVE seven segment display i am using 7447 seven segment display ic.How this ic can be used. how i connect my output from calculator (Binary form) to this 7447 ic. plz reply soon thz (...)
You didn't say exactly which board you have, so here's an example that builds in Xilinx ISE 9.1i and runs on the Xilinx/Digilent Spartan-3 Starter Kit. The "hex_display" module displays a 16-bit hex value on the board's multiplexed 4-digit LED display, with adjustable brightness. The "top" module assigns the FPGA pins and includes a (...)
before using lm35 & adc interface, simply send a fixed value, lets say "52" to the display. for this make a lookup table for each digit 0-to-9 having it's corresponding seven segemnt code. The 2 displays will run in multplexed mode. after you get the value then take the adc & lm35 and read the value & then transmit it to display.
I need to display a 3 digit number using 3 seven segment displays.. For Ex 516 How can I convert the number into hundred digit(Ex: 5), ten digit(Ex : 1), one digit(Ex : 6) using MPLAB assembly coding? Thanks in Advanced!
Do something similar to: case ({j,k}) 2'b00 : out <= out; 2'b01 : out <= 1'b0; 2'b10 : out <= 1'b1; 2'b11 : out <= ~out; endcase so that you can use the bits to control the 7 segment display or you can also use a seven segment decoder =)
I Want to interface 7segment display with Assembly Language using parallel port... The problem is Parallel port has 8 outputs and I want to connect 8 seven segment display....how should I Do it...? if using Multiplexer IC...then which will do my work Perfectly..?

hello i m building a circuit consisting of a seven segment display and its driver. i use a 7447 and a anode one if i want to switch from TTL to CMOS , with which IC i must substitute the 7447? is the 4511 a substitue of 7448 or 7447? thank in advance
Hi, Introduce 1ms timer interrupt. On each interrupt select one seven segment display and display its contents. continue the same method for the rest of the displays. On the main loop go on checking your adc etc.. Since it is interrupt driven, the display will update without flicker. (...)

to whom you are interfacing seven segment? with microcontroller??
Here's pseudocode for what you want: for each digit select digit i by grounding common cathode apply seven-segment drive for this digit end for This code will need to sequence through the digits at least 40Hz or faster. However, don't scan too fast since that will reduce the apparent LED brightness.
16 seven segment, every seven segment have 8 output. So, can do matrix connection in form 16X8 matrix. Here example 16X8 matrix (but in LED). Other option, you can extend output using shift register 74595.
Hi, i have a small problem about seven segment display sizes. can anyone tell me the sizes of seven segment displays available in the market(0.5", 1", 2".....). and also i need to know about the current which is required to light all the pins with normal brightness(1.5" = to light up (...)
