hi im new to motor control using L298N chip. i find it odd to controlling it using PWM for speed contol. the DIR LED both FWD and REV lit up when it runs but the motors runs perfectly well.. but if im not injecting PWM on the ENABLE pin the DIR LED lit up one at a time during their respective direction.
Question is- Is this a normal behavior? aside from unusual LED behavior i found nothing else is wrong. the chip is not heating up above normal temp. the motor runs smoothly, i even tried to run the motor for an hour and i cant find anything wrong with it.. just this LED thing that is bothering me. Im afraid this might shortens the L298 life if its not a normal thing.
Please help me im lost at this stage.
I have attached the schematics and some snips of my actual circuit board.
EN PIN always on
PWM injected on EN pin
