Getting Started

An small example program to create a CANSparkFlex object is as follows.

import com.revrobotics.CANSparkFlex;
import com.revrobotics.CANSparkLowLevel.MotorType;


new CANSparkFlex(, MotorType.kBrushless);

Documentation

The Spark Flex allows you to test the motor controller PID, run the motor at a set percentage, and update the firmware all from the REV Hardware Client. Installation of the REV Hardware client is required to use the SparkFlex for YAGSL.

Make it spin using the REV Hardware Client

The Spark Flex must be disconnected from the CAN bus on startup to run via the REV Hardware Client!

Tuning PID

To tune the PID of the Spark Flex you need to open up the REV Hardware Client select the Spark Flex then open the telemetry tab and set it to position control while messing with the parameters in the lefthand pane.

YAGSL Checklist

• Set all Spark Flex's to unique CAN ID's.

• Update all Spark Flex's to the latest firmware.

• The Spark Flex rotates the motor counterclockwise positive. (Invert the SparkFlex programmatically if it does not rotate counterclockwise positive).

• Tune the PID value's for one drive motor.

• Tune the PID value's for one steering/azimuth/angle motor.

Communication

The Spark Flex is only capable of communicating via CAN and may see some exciting new features soon with CAN FD support!
