Hi there, • this is my first video. • I'm a beginner in electric design. • I'll be posting my new Projects in Logisim here. • I have planned a simple MIPS CPU, with the Basic Instructions and some other stuff. • Back to the Clock: • I made 4 separate Counters, • One is for the first 7-Segment display. It counts to 10. • The second display counts to 6. • The third counts to 24, I explain that in a moment. • The fourth counts to 2. • I used a 5-Bit Decoder for the Display and a CarryOut signal. • The CarryOut signal is always the same, but not in the third Display. • CarryOut is set if the counter jumps back to 00000 and leads to the next counter. • There it is used as a clock signal. • For the third Display i needed more than one CarryOut signal for the same number, so i had to expand the normal 4 bit decoder to a 5 bit. • To simulate the Clock you have to set the low signal of the clock(CLK) to 120 and the frequency to 2 Hz. Everything works fine, except for the first minute. It sets it 10 seconds earlier as expected. after that first minute (50 seconds) a minute lasts 60 seconds, as it's supposed to be. I know how to solve this problem, but this needs another more complicated approach. So I'll stick with this. • If you don't understand it completely you can download it here and have a look: • http://www10.zippyshare.com/v/9940768... • Thanks for watching.
