CAn u send me a little complete example code of the procedure....
then i may follow it and contruct what i want.
Actually i dont have any concept of what u ppl are talking.... i know somple VHDL:cry:
I WANT TO SHOW THE INPUT(7 DOWNTO 0) TO 2-DIGITS OF 7-SEGMENT ON FPGA.
LIKE 8b'11111111 means 100%
8b'00001111 means 50%
8b'00000000 means 00%
now i want to display this 00,01,...10,11..... 50,...99 on two 7segments.
one thing more how will i calculate 11111111 is 100% and so on...
means that:
make every bit to zero, of counter_out1.
its another form of counter_out1 => '00000000';
when u dont want to write this string of zero or u r not sure of typing exact number of zeros then the above qouted method is good to use.
i hope i answered ur question appropriately...
vhdl eq
actually i have writen a counter to count number of pulses.
now, i want to:
1. calculate the following:
(no. of pulses counted ÷ total expected pulses) x 255
NOTE: its same like calculating percentage.
2. i have used 255 because it is represented in binary 11111111.
3. this...
ano ang emotional quotient o eq-tagalog version
(NO. of pulses / total pulses) * 255
then round off the result and convert it to binary.
ANY IDEA OR SOLUTION????
i haven't written any test bench. i solve my problems with force command.
anyhow, if there is any other solution to solve the matter [count number of pulses in 1sec], then do tell me.
this code was only a try from me. may be i m thinking the problem in a wrong way.
LOOKING forward for you...
thanx. i appreciate for ur concern.
well the last few statements are to be edited. so i will definitely remove this.
But my main concern was that:
i want to count pulses received at feed_in in 1sec.
i wrote this code but it is not working.Need some one to debug it.
ir sensor circuits
Thanx for the advice. actually dont know which is the exact folder for this topic.
so the problem is:
i want to implement a feed back system which will read rotation of the the DC motor. now i m going to use IR-sensor. i need to know that what shall i do to make my IR-sensor...
ir distance sensor circuit
I want to make the IR receiver highly sensitive that i could detect the IR light across the DC motor DISC. it will have to generate a pulse when a cycle is completed.
+10points will be awarded to a person who provide early exact solution.
i need it to implement and...

I want to make the IR receiver highly sensitive that i could detect the IR light across the DC motor DISC. it will have to generate a pulse when a cycle is completed.
+10points will be awarded to a person who provide early exact solution.
i need it to implement and show on this Monday.
fpga reading ir
HOW TO READ NO. of PULSES USING FPGA(SPARTAN-3).
the IR will generate a pulse at every complete cycle of a DC motor(2400rpm).
now i want to to count the number of cycles in 1 sec.
