model i need to build. Yet, it doesn't work :(
the purpose of the code is very simple. I have a step motor i connect to a circuit matrix. the circuit matrix has a ULN2803 transistor. And the matrix is connected to an Altera EPF10K70 device . i need to make the motor turn right at my command (pressing a button on the altera) and turn left at the pressing of the other button. every button pressing is to adjust the motor to the side by a click. Meaning, that one short press only moves it slightly, and a long press keeps it moving until i stop pressing it.
but it doesn't work :(
I have to assign this project for next sunday, or else i'll flank this course.. pls people - i desperetaly need ur help!
here's the code i did:
entity MOTOR2 is
(out1_rl, out2_rl, out3_rl, out4_rl : out std_logic;
right, left : in std_logic);
architecture behave of MOTOR2 is
VARIABLE temp_rl : INTEGER RANGE 1 TO 4;
if (temp_rl=1) then
if (temp_rl=2) then
if (temp_rl=3) then
if (temp_rl=4) then
