in this 0 all represent correspond mosfet is on conducting...in this first two 0's represent s1 and s2 is conducting..next 0's represent s7 and s8 of 6 volt is...
am using oly 16 so in port d and port b for output...through those ports am giving high or low signal to optocoupler inorder to conduct the mosfet

am 0ly giving the digital signal 0's and 1's

the bits in the order rb0 to rb7 and rd0 to rd7
intially the 3 volt h bridge should ON..by pic we giving signal through optocoupler and make s1 s2 to conduct,,,next 6 v should on likewise we should ON the mosfet switches simultaneously to get the sign output like i showed u before

just show how to change the code for...
just a min i ll show some things in my project take a look and suggest some new things
