    HOW TO DISPLAY 8'b VALUE INTO TWO 7-SEG DISPLAY

    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...

    Circuit - IR sensor to read at <3cm distance (+10points)

    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...

    HOW TO READ NO. of PULSES USING FPGA

    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.

    WRITE A VHDL CODE for the following (+20 point reward)

    vhdl code for pulses at 50mhz *only exact solution will get the reward. URGENT SOLUTION NEEDED. Problem: i want to count number of pulses of a DC motor operated at +5v. the clock used in controller was 50MHz. The Design consist of PID (16-bit output,8-bit input and feedback) +PWM.the #of...

    INTERGER TO BINARY SCALING(VHDL)

    binary scaling if the frequency is 50MHz. i get approx. 50,000,000 pulses in 1sec. when i will read it from the sensor then and count them. then how can i put this huge integer values on 8-bit binary scale. means: 50,000,000 => '11111111' 00000000 => '00000000' it works same as...

    HELP: To Drive DC motor and get it feedback, uning PID FPGA

    dc motor fpga If anybody can tell me how to measure the speed or rpm of a DC MOTOR. if i m giveing the digital PID controller output to PWM and then driving DC MOTOR TO CONTROL SPEED.now i am stuck at giving back the feedback to the controller. i have few ideas: :idea:1. use LDR and LED circuit...
