Dear all, I am facing problem in displaying floating point number coming from ADC after conversion. I have attached the code that I have attached the code for this. I want to display like 92.66677.... I have attached the image also. Please help. /** * \file * * \brief Empty user application template * */ /** * \mainpa
Dear all, I am having doubt in display floating numbers into seven segment display using AS1115 driver. I have written a code for this but I am not getting place values in the segments. I have attached the code for this. I am getting values as in the image I have attached. I need to display 92.23451. This is value coming from ADC. /
Hello everyone! I have a problem. I'm supposed to create a countdown timer from 9 to 0 on a 7 segments display in MP LAB with PIC 16f877A. Now the problem is that I have to do this due tommorow and we never studied programming at all. During classes the teacher just gave us printed asm files and have us type them in MP LAB. Now, in order to pass th
Hello everyone! I have a problem. I'm supposed to create a decreasing binary counter(countdown timer might be the term I guess) from 9 to 0 on a 7 segments display in MP LAB with PIC 16f877A. Now the problem is that I have to do this due tommorow and we never studied programming at all. During classes the teacher just gave us printed asm files and
Hello All, I am developing a circuit in which PIC16F877A controls the peripherals, one of which is a TM1650 7 segment display driver chip. The datasheet is in Cantonese and I cant understand it. Has anybody worked with the chip and help me on that count? With regards, Abhishek
Dear Sir, I am interfacing AS1116-BSST driver with AT32UC3A1256 using SPI. I am able to read all the inputs and outputs in CRO(Clock, Data, Chip Select).

Hi, Does anyone know of graphical IDE software for FPGAs, like EdSim51 or Moravia MCU 8051 IDE for micro-controllers. I am looking for a package where I can see the outcome of the code on seven segments, LCDs, serial ports, PS2 ports etc without having to actually program a development board. Thanks, Arvind Gupta.
i use a 4 digit seven segment display for my project. but it need to show a number in first 5 second and then other for 5 sec, then the previous one is shown and the loop will be continued. for this i use the program but it shows 0000 . ################################################# void loop() { print_seg(10.76); delay(5000
Hello I'm usnig ATmega8 with ADE7753, display on 4 digit seven segment. I already read/ write ADE7753 register's bits n display register's default value on 7-segment (e.g. I read MODE (0x09) register's default hex value (0x000C) and displayed on 4-digit 7 segment like 0012 in decimal). Means there is no issue with SPI communication, read/

Hi Everyone i'm using PIC16f690 interface with two seven segment by 7447 im making 0 to 99 counter by using timer 0 of pic controller i write a code but it shows only ''0'' on my both 7 segment... can anybody please help me to figure out the problem Thanks The CODE IS... #include #define _XTAL _FREQ 400000
i am driving 8 seven segment display with max7219 multiplexing ic along with pic microcontroller. some times during power on max 7219 sets hanged by displaying all the 8 digits seven segment as 8.8.8.8.8.8.8.8.8. and sets strucked but the pic micro is working. this happens only on power on once in 4 times approx. kindly help.
Good afternoon. I want to offer my services in PCB design. I have about seven years' experience in designing circuit boards of various interfaces and data transmission requirements: 10 gbps Ethernet, PCI, PCI-express, UART, with DDR3 memory onboard. I have knowledge of design of rigid-flexible circuit boards, circuit boards with blind and buried

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), which doe

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 segments not as per the MCU control. 2) digit "6" and "9" are no
There are too many terms required to generate the Q0 output. You require a part that has more terms. That's the way I remember it, too: that some of the outputs had fewer product-term inputs than others. But I can't find a data-sheet on line that shows that: they all have seven inputs, which should be enough. May
Hello! I am new to CPLDs... I am working on a project and in the middle it has been decided to include a more advanced LED panel than what was planned initially. This would require additional 40 to 45 IO pins than already available on the MCU. There is also a need for decoding the MCU output signal, eg binary to seven-segment. I thought of using
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
So, one times I generate in receptor the 3 bits (which if the 3 bits are 0 there is not error) to correct the seven bits I must put a and gates with that 3 bits (because 1-1-1 are seven) and the output of the and gates make the parity (with xor gates) whit the seven bits. right?

Hi, I am very new to proteus and would much appreciate a little help. I have made a schematic in which to count with 2 seven segment displays. I thinkit is all working as I can see the red/blue switching colours. But the displays remain dark. I think I have them powered but nothing. They are common cathode. Any advice would be gratefully wel
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 controlling the You will be having 2 enable pins in the display to
If I remember correctly, Bharat Electronics (BE) makes them, even jumbo size single seven segment LCD plates. may not be display modules. Coming to things like 16*2 20*4 etc modules, Hyderabad based LAMPEX used to make them. perhaps their registered office might have shifted to Mumbai. ps: here is their link

Many apologies if this is the wrong place to ask this question, but I was wondering if anybody could help figure out what this (see picture...BAD picture) is? Circuit has a GAL16V8B chip, a seven pin socket connector (4, and 3) and was inserted on an old comm equipment mobo into a 24 pin socket parallel to a UV prom. Is this possibly a one time UV
