Microstepping (16 steps)

[Sweta25]

Hello,
I am encountering a problem with microstepping.
for full steps:
when "00" => dout <= "1000"
when "01" => dout <= "0100"
when "10" => dout <= "0010"
when "11" => dout <= "0001"

for half steps:
when "000" => dout <= "1000"
when "001" => dout <= "1100"
when "010" => dout <= "0100"
when "011" => dout <= "0110"
when "100" => dout <= "0010"
when "101" => dout <= "0011"
when "110" => dout <= "0001"
when "111" => dout <= "1001"

for microsteps (16 steps):
when "0000" => dout <= "1000"
when "0001" => dout <=
when "0010" => dout <= "1100"
when "0011" => dout <=
when "0100" => dout <= "0100"
when "0101" => dout <=
when "0110" => dout <= "0110"
when "0111" => dout <=
when "1000" => dout <= "0010"
when "1001" => dout <=
when "1010" => dout <= "0011"
when "1011" => dout <=
when "1100" => dout <= "0001"
when "1101" => dout <=
when "1110" => dout <= "1001"
when "1111" => dout <=

Can someone help with the microsteps???? I tried many pattern but in vain...any help would be appreciated...Thanks in advance

Hi...

Micro stepping is some what different from full and half. You cannot do that via code easily.

Refer the given link datasheet , You can understand better about microstepping

ohhhh is there no option left???

Use microstepping stepper motor driver..

Consider torque and current of your motor
