guys, how about a digital clock using pic16f84a?? do you guys have any suggested sites??? because just like muralibhat i didnt got a specific result of this project using pic16f84a.... pls help!!! coz starting today i only got 10 more days left to do it..
Thanks I have dowloaded Hitech Picc LIte compiler just to know the how easy it is programm in C but I cannot install it becos it gives the message that the MPLAB IDE is 6.5 version or higher but My IDE is 6.0 version.
Please help
Thaks everyone who cooperated
I have finished the circuit and the program but the clock i.e.DS1307 starts only if I touch anu pins of any IC or positive terminal or ground. I cannot figure out the problem.Please Help
Hello, I have connected the caps but still it is not working . If I switch off the power suplay and turn it on after some time I found that the clock has incremented(Even If I do not touch the pins). I clock comes to halt only if I aplay power to PIC.As i explained earlier If I touch the pins then the display shows the clock increment
Hmmm... are you clearing the 'clock halt' bit in the ds1307? Look on page 8 of your data sheet:
Please note that the initial power-on state of all registers is not defined. Therefore, it is important to
enable the oscillator (CH bit = 0) during initial configuration.
Thanks BEE BOP,
I found the problem---I had connected a different power suplay for backlit(LCD)That was making the problem.Now I have connected the same power suplay which I use for the circuit.
Now I have a different problem i.e. I cannot write to Ds1307 with new data. Is it neccessary to HALT the ds1307 before writing?Note that my clock is working and it starts from 00:00:00 and 01/01/00
