HI to everybody,
I am new in this forum and I need a help for my project (rover).I want drive two geared motors as this schema:PS2-->SKPS-->SK40C(PIC16F877A)-->(2)MD30.After charging PS23+SKPS sample code HEX this is the result:motors can run both CW or CCW so that they can move the rover forward and backward;motors can also run (one CW and one CCW)so that the rover can turn right.I was espected to can run motors (one CCW and one CW) to turn right but only one motor run CW and the other not runs so that rover cannot turn left.I have tried using various motorcontrollers(ad example the same Dual H bridge in the PR23 schema)with the same result.I tried to use single motor control alternating connections betwin RC1 and RC2 and I think that command signals from RC1 line are not like espected.For better understanding that is what happens when I press joypad buttons: LEFT-(motor1 cw-motor2 cw)//RIGHT-(motor1 ccw-motor2 ccw)//
UP-(Motor1 cw-motor2ccw)//DOWN-(motor1cw-motor2 stop).Regards Carlobot
