Hi all.... i am trying to interface 2 digit x 3 seven segment with 89s52. one to show secounds, one for minute and one for hour. it works proper... the only thing is i does not stay stable.... i mean the display blinks. please help me where i am wrong code is.... #include #include unsigned char (...)
Hello everyone, I am confused about my BASYS2 FPGA board's common anode seven segment 4 digit display's function. In user manual(and also tested in Verilog code), the desired digit is enabled when the anode is driven to 0(e.g. to enable the rightmost digit the bus should be 1110 each of which represents the anode signal, respectively), (...)
Hi all, here i interface 4-seven segments(common cathode) with atmega8 (avr gcc compiler). My initial task is very simple that i need to display 0-9 on each display one by one... but i faced two problems.. 1) segments are not switching...means data is displayed on each (...)
i have project in which i want to use 7 segment for two purpose, 1.. for display to set value 2.. for show adc value how can i get it
Hi there, I am trying to interface a HEX keypad with to display the key pressed on seven segment display. I am new to HEX keypads. I have read some theory about HEX keypads. But I am unable to make the decoder. Can anyone pls provide a sample code for it in VHDL (I am OK with seven (...)
It can be done but I dont think you will find 3 digit bi color seven segment displays and also you won't get colors with yellow and green. Even if you are not getting that take 3 numbers of bi color seven segment displays and connect the terminals together to work as 3 digits. For (...)
2 common cathode 7 segments and pic 16f877a and mikroc pro for pic 2 transistors connected with RD0 and RD1 , the RD0 transistor is responsible about the tens digit and the RD1 transistor is responsible about the ones digit the 2 common cathode 7 segments are connected to portb code : char x,y=0; // x for ones and y for 10s char I;
Hey,thank you Sir for the response I want to display on seven segment and I would like to be able to set the time,to update the system if possible.I am using PCF8583 not DSO1307. Thank you!!
Hello there, I have a FPGA board which has 4 seven segment elements having all the elements connected in parallel ie. element 'a' of all four units are in parallel and so on. I wanted to display four distinct characters in the four units viz 'F.P.g.A.'. Is there any way to do so. I tried the following way: Described a process A (...)
First of all, i'm sorry for my english. I want to make a 7 digit display using verilog. I'll test the program on spartan 3E. An exemple: I know that i need to use frequency divider, but i don't know how to implement the program. I'm beginner in verilog, but i want to learn with exemples.
You've got numerous problems in this code. Not a problem but easier to maintain...Use Verilog 2001 C-syntax for the module ports: module bcd_to_seven_seg ( output reg bcd1, bcd2, bcd3, bcd4, //declaring each 4-bit decoder input din, clk, enable, output reg qout //shift register values ); [
Goodday! I need your help. I need help in coding ADC of the Zilog Microcontroller that will display output in seven segment. I used Zilog 40 pins. :grin:

As I understand your circiut.... you need to make Port P0.2 to P0.6 controlling the seven segment displays ..... So you can use interrupt timer for multiplex them..... Generally way that it is done is running 3.2ms interrupt timer in the micro-controller... With regards, Milind
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 (...)
hello friends' i have problem in hexadecimal to decimal conversion,actually i have a switch connected to port 1 of 8051 and show the count on seven segment but after 9 data is mismatch ,can any body plz send me the code to display that count on seven segment display. Thanks in (...)
You should be using a function to display the integer on the seven segment. So always display four digits, whether it be less than 4 digits. Add a 0 in front. When you write your function in this way, it becomes easier..
Hi, I am trying to display different sensor readings on 7 segment in a circular sequence I stored both the sensor readings But I have problem while displaying the the segemnts. I saved the sensor readings in two different arrays Code: type dbuff is array (0 to 3) of std_logic_vector(3 downto 0); signal x:

If you are using individual seven segment display then the pinout is probably like the one shown Interfacing to 7-segment displays You can check if it common anode or common cathode with a multimeter in the diode function or a 5v source with a 270 ohm resistor in series, you can also use it t
In this case you need to use a Common Anode 7 segment LEDs display. seven segment display Common anode to be connected to the Vcc pin. Look here for an example how to connect the 74LS74 with the 7 segment LED display.
hi...i currently working mu final project that would need me to use this conversion. Here what i'm trying to do: 1. let say i have this number in decimal 6.23456. I want to multiply this value with other value (integer) and display the result ( in fraction num) on seven segment using verilog code. for example: value a=6.23456 value (...)
Hi Demise, You are displaying the target floor in a seven segment display na... so maximum value will be 9 (0 to 9) so you can make an input port of size (10, like std_logic_vector(9 downto 0)) to act as a switch, for example so if you need to select the target floor as 6, then you need to press the 6th pin as active (...)
