the reason is I have hundreds of Diode(LED) in the design, their Vcc is common, and they are GNDed via individul current source.
in order to lower the cost, I'd like to drive only one current source for a singal LED sequently and detect the current on the common Vcc wire.
I need to make a current detection circuit for a Diode. and please help me to find a IC or a good circuit to detect the current.
a brief description is:
The cathod of the diode is GNDed via a current source and the anode of the diode is connected with Vcc directly. the purpose of the detection...
normally, a digital logic should be syncronoused, I want to know it has to be?
I have a case:
input of the logic is mechanical sensor for distance. the value of this very be stable when we read it. the function of the logic is just convert the value out of the sensor into a readable one.
In...
[HELP] counter on GAL
thanks well, I vote you for "helped me"
I am sorry for choosing the wrong forum, but it is lucky that I still get the answer, I will be careful next time
[HELP] counter on GAL
Hello
I am a fresh man of logic, can any body give me a hink to make a counter with GAL?
the function I need is just divided the clock.
I can do it my uP, but I don't know how to do it by a simple logic.
Thanks
