If mixing mode is disabled, only channel 1 affects motor speed. Calibration can have a significant impact on performance. The wizard instructs you to move your inputs to their extremes and maps one extreme to the maximum forward motor speed, the neutral position to speed zero, and the other extreme to maximum reverse speed. We recommend your first step after connecting your analog voltage source be to use Quick Input Setup Wizard in the Simple Motor Control Center G2. In analog mode, the channel values are mapped to motor speed based the channel calibration values and the mixing mode. The analog channels are read with 12-bit (0.8В mV) resolution.

For example, you can use the serial interface to read the analog channel values while the motor controller is in RC mode. The Simple Motor Controller G2 is constantly sampling the two analog channels and making the measured voltages available via the USB and serial interfaces, even when the controller is not in analog mode. Wiring diagram for connecting a potentiometer or joystick to a Simple Motor Controller. Simple wiring example: connecting to a potentiometer The channel pins have a 0.1' spacing, which means that a female-female servo extension cable can be used to connect a potentiometer or analog joystick to the controller. If your control source outputs voltages higher than 3.3В V, you can use a voltage divider to ensure the voltage is always at an acceptable level. Note: The analog channel inputs are not 5V-tolerant, so you must not connect voltages over 3.3В V to these pins. If you need to use a higher-resistance potentiometer, you can disable potentiometer disconnection detection from the Simple Motor Control Center G2. Higher-resistance potentiometers will not work well with the potentiometer disconnection detection feature. We recommend using a potentiometer in the 1В kО© to 10В kО© range. If you use an analog voltage source that is not powered from the Simple Motor ControllerвЂ™s potentiometer power ( + and в€’) pins, you will need to check the вЂњIgnore pot disconnectвЂќ checkbox under the вЂњAdvanced settingsвЂќ tab of the Simple Motor Control Center (see Section 5.3). These potentiometer power pins are special in that they allow the Simple Motor Controller to detect if an analog channel has become disconnected, so we recommend using these pins rather than alternate power supplies or other pins on the board. Each channel has a signal pin and a + and в€’ pin for powering the analog voltage source.

The analog connection block consists of two channels.

High-Power Simple Motor Controller G2 18v25 or 24v19 analog connections. High-Power Simple Motor Controller G2 18v15 or 24v12 analog connections. Typical analog voltage sources can be powered directly from the Simple Motor Controller G2. The Simple Motor Controller G2 can derive the motor speed from a single analog input channel, or it can mix the signals on both analog channels to generate the motor speed, which makes intuitive throttle+steering control of a differential-drive robot possible using a pair of controllers. The analog inputs can serve several functions, from directly controlling the motors (Analog input mode) to sending signals to an autonomous robot (Serial/USB mode) to providing limit or kill switch inputs (any input mode).

Simple Motor Controller G2 can be directly connected to a 0В V to 3.3В V analog voltage source, such as a potentiometer or analog joystick, allowing for simple manual motor control (e.g.
