i am using l298 to control 2 dc motors & i used pins 1 & 15 to sense the current through 0.5 ohm resistor by ACD in PIC , but there is a problem that when the load increase at the first motor the current at the second affected ,the same for the second motor too, i don't know why , i can't know the real current of each motor because of this problem , i need help

,,
thanx in advance​

 

Post more information. Post the schematic. Post any pictures or information you have on the motors.

More info equals more help.

I'll bet that you have a poor ground side connection on your Rs1 and Rs2.
