i want to use a Halleffect sensor(Pololu ±30A ACS714 Current Sensor - RobotShop) in combination with the TWR-KM34(Kinetis M3). According to the Ddatasheet the differential inputs accept a voltage range of 1V (+-500mV).
But the sensor exclusively has positive output: centered at 2,5V +-400mV
Does the firmware of TWR-KM34 properly work if my input signal is 0 to +500mV(so i could simply use a voltage divider)?
Or is it possible to change the input rane of hte ADCs from +-500mV to 2V+-500mV?
