Hi, i have i servo-moteur that i will drive from an msp430, i would like to insert a shunt in order to mesure the current, if the current exceed 300 mA the mcu will stop the servo, the problem is that when i place the shunt between the 0 of the servo and ground, the servo will vibrate and this is the easest way to measure current, and when i place the shunt between the VCc of the servo and the supply voltage the servo run normally but i don't know how to measure current in this way, HELP PLEASE
