In fact the DCM only allow to divide the clock to a maximum of 16. My bord work with 12MHz, so the mimimum would be 750KHz. not enought to get 1HZ and so on!
The RESET signal is drive by an external switch and no debounce add to it because is working, is reseting the sistem. Is an external...
Yes, i´m aware that.
I was to redo the entire managment clock with the DCM module but it would lose some time to familiarize myself with it and have to move on.
Your idea sounds good too, but I ended up going to my mediated change a module already made in one of the book's examples...
People. My code doesn´t give me any assincronous/latches/clock enable warnings. Only signals that aren´t being used. I have attached a better picture.
It's now non-stop working :)
All Synchronous signal stand according to the following form:
process (<Clock>)

ok i´m goingo to do new simlutations test. this time for failure.
I have an assynchronous RST switch i you can see in the image.

Hi
I am experiencing bad times with my project with a spartan 3A XC3S200A fpga. What happens is that the project works perfectly in simulation (ISIM) but when programming the fpga the result is not entirely expected.
Works for a while and then completely blocks. I'm suspicious that exist delays...
I've been studying the implementation of single board computers, and started to see the types of architectures from ARM RISC processors and SoC's. Now there are things that I can not clarify.
My questions are:
1 to implement a single-board computer, for example, in the format PC104, we need...
i
i can shift a range of voltage of 0V-3.8V to 0V-10V. is there any opamp who do the job?
i think it would be better to make a normalization of the signal. so that 0V-3.8V => 0V-1V and them with an opamp =>0V-10V.
anyone have another suggestion?
thank
i think you need something like this. i can only tell you that the time constant of a capacitor tc = C*R, like n this circuit.
or maybe you need something like this:
**broken link removed**
if the pulse is the only source, storing the same signal at the output you would never have all the 3V, because off losses. you would need an amplifier.
Jiripolivka is right,
try to look at this

so suddenly I'd say it would be necessary to store the pulse in the condenser. then applied to a gate of a transistor with an RC circuit time constant set to 0.5 seconds. after that time the transistor circuit would triggered the stored pulse
thanks
it's not for any specific project. its just a study that i´m doing that, probably, i will need in the future. the ideia is to make a list containing the best amplifier circuit (discrete or integrated) to the respective sensor which in turn is used for a particular application.
