Servo Hub firmware 24.0.4

Initial Servo Hub Release

• Control servos via RS-485 or CAN
• Channels can be enabled/disabled individually
• Channels can be powered on/off individually
• Status LEDs show the current state of each channel
• Adds over-current protection per-channel

SPARK Flex firmware 25.0.4

• Fixes bug causing the reverse limit switch enabled setting to not apply
• Fixes bug causing the forward limit switch to latch its latest value when it is disabled

SPARK Flex firmware 25.0.3

• Fixes CAN error state on disconnections

REV Hardware Client 1.7.0-frcBeta2025.1

General improvements

• Further improves the reliability of displaying devices on a high-traffic CAN bus
• Fixes a performance regression in the 2025 beta release that affected CAN communication

Servo Hub

• Adds Servo Hub support with the following functionality
  • Updating firmware
  • Setting the CAN ID
  • Actuating servos

SPARK improvements

• Improves UI for configuring closed-loop parameters (including MAXMotion parameters) on the Run and Telemetry tabs

REV Hardware Client 1.7.0

Breaking changes

• The standard REV Hardware Client installer no longer bundles device software files that are under 5MB
  • If you need an installer that has device software bundled into it, download one of the offline installers linked at https://docs.revrobotics.com/rev-hardware-client
• Once a REV Hardware Client instance starts controlling a SPARK motor controller, no other REV Hardware Client instance connected to the same bus can control a SPARK motor controller until the first instance exits
• The "Follow SPARK Using Preset" feature has been removed, in favor of simpler follower mode parameters in SPARK firmware version 25 and later
• The "Burn Flash" button for SPARK motor controllers has been renamed to "Persist Parameters" to match the 2025 version of REVLib
• The SPARK parameter kSensorType is no longer automatically-updated when the kMotorType parameter is changed
  • This only impacts SPARK firmware versions prior to 25.0.0, as the kSensorType parameter has been removed from later versions
• The MAXSwerve Utility now requires SPARK firmware version 25.0.0 or later

General improvements

• Fixes issue where the installer could cause the computer to reboot unexpectedly
• Improves the reliability of displaying and using devices on a high-traffic CAN bus
• Fixes a performance regression in the 2025 beta release that affected CAN communication
• Stops the Telemetry tab from breaking after a device that was providing data is removed
• Fixes issue where Android devices that have a type other than "device" or "recovery" would cause device scans to take a long time and not include any Android devices or Expansion Hubs
• Only allows one instance of the REV Hardware Client to be open at a time
• Fixes an issue where Pneumatic Hubs and Power Distribution Hubs would be disabled when a SPARK motor controller is commanded to run

Servo Hub

• Adds support for updating, configuring, and actuating servos on Servo Hub

SPARK improvements

• Adds support for SPARK firmware version 25
• Improves UI for configuring closed-loop parameters (including MAXMotion parameters) on the Run and Telemetry tabs
• Fixes issue updating SPARKs over the CAN bus
• Improves organization of parameters on the Advanced Tab
• Improves organization of faults and warnings on the Basic Tab
  • Some faults were renamed or combined
  • The statuses of the soft and hard limits are now displayed above the faults and warnings
• Exposes individual faults on the Telemetry tab
• Improves organization of SPARK signals on the Telemetry tab
• Many under-the-hood improvements

REVLib 2025.0.3

Changes for Java and C++

• [SPARK] Improves documentation concerning Relative Encoders and Position and Velocity Conversion Factors
• [SPARK] Removes setPositionConversionFactor() and setVelocityConversionFactor() methods from the sim classes
  • Instead, use the appropriate Config objects and positionConversionFactor() and velocityConversionFactor() methods
• [SPARK] Fixes crash when calling Spark[Flex, Max].configureAsync() in simulation

Changes for LabVIEW

• Fixes issue where an error would be incorrectly generated when configuring follower mode

REVLib 2025.0.2

Changelog:

• [SPARK] Improves SPARK error messages by adding the invalid value which caused the error
• [SPARK] Improves SPARK error messages by displaying the parameter name as well as its ID
• [Servo Hub] Fixes uninitialized variables
• [REVLib] Fixes issue where REVLib doesn't clear a previous error (as viewed through GetLastError)
• [REVLib] Fixes threading issues encountered while running Googletest unit tests
