Do you need to do it with flip-flops? Can you use a one-shot? A simple 555 circuit can do the trick for you.
Hi guys,is there anyway I could get time delay using D Flip flops?I've tried googling it but all I get is info. on 555 IC timers. What sort of time delay do you want (1mS, 1 min...)?
I find the make monostable time delay IC. What kind of IC exist? (except lm555 IC) Thanks.
A 555 timer IC is an easy and common way to do what you are describing. Below is a method which is more or less When the input goes high, the capacitor begins to charge. After a second it reaches about 1.
what is the formula to convert the time delay into tolerance of the signal length with respect to core material ?
Hi, I found a simple program for calculate a time delay for 8051 uc. I write simple blink program too to test this program. It's just a led blink every 1s (1000000 us) I used the delay routine generated from above program. It very helpful for beginner. Program+Blink Example in ASM and Proteus here. Bye Pharaoh Of Egypt
Hi all, Please provide me with how i can use one of the 8051 timers to calculate a time delay equal 1 second. I'm using XTAL frequncy 11.0592 MHz. Regards.
Hi all, Any idea as how to create long time delay using 16f628a timer overflow interrupt, so that cpu is free to do other task? I need some function written in CCS PIC for the same? Thanks
In verilog, we can use apply b to a after a time delay: a <= #10 b But in verilog-A, how can realize it? Here is the verilog-A code: integer a; integer b; @(V(clk),1) begin a = b; end Simulation shows there should be some delay when applying a to b. Now my method is apply b to a electrical first, then apply the electrical to a. (...)
