L298 current sensing + pwm
hi, want aply pwm on solenoid controling flow of gas valve. possible measure current using sense pins of l298 when used in pwm mode? how connect microcontroller?
the voltage across sense resistor pwm , need amplifying low pass filtering make usable analog feedback signal.
what solenoid current?
or, use 1 of these, (or similar), still need lpf.
