hello all,
our project involves converting the square pulses from PC to the readable DC voltage.this gives the spindle motion and position of the CNC machine.
so we have a software which generate square pulses and send them through pin6 of parallel port.all we need is converting this signal to analog DC voltage.
we tried several chip like LM331....but its not working.we can't use LM2917 as its not so precise.(chip shld be able to give as min as possible voltage against the input frequency)
the output we need is like for 1Khz--->1volt
2Khz---->2volt
so guys is there any other chip which can carry out this task efficiently?
if any one has idea abt it pls help
thanks
