================================================================================ Analog Input ================================================================================ Analog inputs can be used to measure voltages between 0 and 3.3V. ODrive uses a 12 bit ADC (4096 steps) and so has a maximum resolution of 0.8 mV. A GPIO must be configured with :code:`.config.gpioX_mode = GPIO_MODE_ANALOG_IN` before it can be used as an analog input. To read the voltage on GPIO1 in odrivetool the following would be entered: :code:`odrv0.get_adc_voltage(1)`. Similar to RC PWM input, analog inputs can also be used to feed any of the numerical properties that are visible in :code:`odrivetool`. This is done by configuring :code:`odrv0.config.gpio3_analog_mapping` and :code:`odrv0.config.gpio4_analog_mapping`. Refer to :ref:`RC PWM ` for instructions on how to configure the mappings.
