Hi ! A quick search for "digital clock schematic" using GOOGLE give me this site: I see that this project is an old conventional digital clock using counters integrated circuits and seven segment decoders. This is pure hardware and no software at all. The restriction is about the
I search in google.
i designed a digital clock using keil c for 89c51. i planned to use 74ls47 for each display and programmed and now i planned to reduce the circuit such that i connect all the 7-segment display parallely in a single port and refreshing it. when i program for this option only the last segment glows. if i give some time delay to refresh then it wor
Where can i get programable timer (clock) schematic diagram?
Anyone got a link or something About a Real Time clock that is is displayed on a 4 7 segment Digits using PIC16f87x and Written in C ? Thanks For your Help
Design a digital clock with the following functions: ? Displays hours, minutes and seconds ? Indicates PM by displaying the decimal point ? Enables the setting of hours, minutes or seconds by having the display increment at a fast or slow speed and then stopping at the desired value ? Without using microcontroller and microprocessor
the minutes displays are upside down and i dont know the pins in the real 4 digets 7-Segment where is the pins in this 83642 from the design Try to read model number from 7-seg, then search datasheet on Internet. Ususally Pin1 starts from upper left corner. tronixstuff.
lol what you need is a relay activate the line a selector to select the digits normaly on the toy and or gate {for a clock 1khz to gate the selector and matrix} and some diodes one for the phone line to modulate it the others for the diode matrix you also need a cheep kids telephone it hasa dtmf chip in it and 8 handy

Hi, I once used an inverter in the MACH4A to 'clean up' a clock, with a couple of resistors to add hysterisis, effectively making a schmitt trigger. However, I'm not sure if what you are suggesting would be a good idea. You may simply have in your main schematic (design) an inverter buffer connected to two pins, but what you actually get may be 3
Go to: Sockets are provided and connected for a LTC1298 A/D Convertor, DS1307 Real Time clock, 24XX Series EEPROM, MAX232 RS232 Communication IC and 75176 IC's for RS422/RS485 Communication. Connectors are provided for program download, LCD units and external connections to all I/O pins In the
I don't want to dissapoint you, but regarding schematics, your board should be much smaller in dimensions. Because this is not mixed signal design and clock frequencies are not high you can place all components closer to save PCB space.
Hi friends I wanna to make one digital clock with PIC16F84. i found two circiuts in internet : and but i havent codes for this IC. can anybody help me? does anybody have a circuit ?? or codes? or new Circuit drawi
Hello I have a design (Verilog) and using a STARTUP_SPARTAN3 instance. On the instance, I send the clock signal and reset signal. The clock and reset signals are comming directly from the top-level clock pin. That is, I have code looking like: module counter_7seg(reset, clk, segLow, segHigh); //Top-level module input r
randika, You can measure time either way (with RB0 and interrupts) or using TOCKI. If you use RB0, I would tie TIMER0 to the clock and at each RB0 interrupt calculate elapsed time using TIMER0. You will also have to handle TIMER0 overflows (I would use interrupts for this as well). The main program can calculate and display the time on the
What circuit can make 125MHz clock to 1.25Ghz and 1.25GHz clock to 125MHz? can someone give me some pdfs? Thanks a lot
You could build the pulse generator using a crystal oscillator plus a small microcontroller, or an FPGA/CPLD, or a few digital logic chips. The accuracy of your clock would equal the accuracy of the crystal oscillator. The microcontroller or FPGA/CPLD would require some programming. You will also need an interface circuit that converts the digital

There are some RTC (Real Time clock) that generate 1Hz signal in one pin only with connect them to 3.3V or 5V power suply. For example PCF8583 from philips. Salu2.
can i use 555 timer as syncronous clock for counter?? ii know the frequency of the 555 timer is very low comparing with pulses generator device; need your opnion please thanks in advance
Hi, Would remain grateful if any one could let me know the www site for 8 Bit Microcontroller Interfcae with Xilinx XC 4000 - XC 9500 CPLD Interface schematic. I'm no expert, but I guess it depends on your application. The term 'interface' it quite vague. A quick search on google I got:

I made a board as this schematic to get 32.768K clock source, but it couldn't generator 32.768K clock freq. I saw more than 60MegaHz at TP25, What's wrong? I don't know how to do to get 32.768KHz clock? any suggestion? or any other fine schematic that could generate 32.768Khz? thank you~~~
I have this radio clock and I don't know why each time the current went off loses the time. Any sugestion? This model doesn't have any battery for backup Some sony model have a dual layer capacitor but I don't see any Any advice? Added after 43 seconds: the picture of the clock

who knows how can real time clock keep track of clock after power down ,what's the relation between RTC and clock unit?
XTAL based oscillator on 7th+ overton, multiplied to your frequency. Sinewave to LVPECL or any other appropriate levels using high-speed low-jitter logic device (I would recommend ONSemi's NB7L216). What is your desired clock rms jitter value?
did you tried google ? e.g.
this method use the control logic on clock path. I think it is not good for ASIC design. Is it there any other method to avoid logic on clock path? thanks
Look at appnotes AN590 and AN615 from Microchip. They feature a clock based on the PIC16C54(A), but you should be able to use/ adaptt the schematic and possibly use most of the code, too.

Hi all I am working on LVDS tx in 130nm technology for transmitting 250Mhz clock (schematic enclosed) I have a Query regarding Gain of CMFB amplifiers According to Common mode & differential mode output swing Specification I decided The transistor sizes of output switching network Now MN2 size comes out to be very high & MN2 Cgs = 992.
Setting the clock speed in Proteus is a matter of editing the schematic component for the PIC and typing in the value beside the 'clock Frequency' property. The very last thing you want to do is hang an oscillator off the pins. The simulation model will ignore it and it will cripple simulation performance. We do it this way both (...)
any quik suggestion.... I am using a PIC with 30 mhz. on pin PIC is generating 7.5Mhz ... this clock I need to feed to PIC itself and other Pheripheral chip... i can see the 5v for PIC output, but when I am connecting directly this pin to PIC input and pheripheral.. then voltage is dropping down to 600mv. i used ac termination but still

Hi, I need to interface my PIC 12-hour clock to another PIC stepper motor controller, had anyone here has a simple schematic for me? What I want to do is to set a time for the clock and at the moment the stored time exacts the current time , the stepper motor will rotate please help, thanks in advance, the_risk_master
Hello, Can someone post a schematic and complied .HEX file for blinking a led using PIC12F675. I dont want to use an external crystal in the circuit and use the internal clock of the pic.The basic idea is to just test the device!
