Important Setup Information for ROBOTC 4.52:

VEX IQ Users:

  • Run the “VEX IQ Firmware Update Utility” and update your VEX IQ Brain to firmware version 1.15.
  • Also update your VEX IQ Wireless Controller and any other VEX IQ Devices (sensors, motors).
  • After updating to the latest VEX IQ Brain firmware, install the latest ROBOTC firmware from inside of ROBOTC.

VEX Cortex Users (with Black VEXnet 1.0 Keys):

  • You will need to update your VEX Cortex and VEX Game Controllers with Master Firmware Version 4.25 from inside of ROBOTC.
  • After updating the master firmware, you will also have to update the VEX Cortex with the latest ROBOTC firmware.

VEX Cortex Users (with White VEXnet 2.0 Keys):

  • The new VEXnet 2.0 keys have a specific “radio firmware” that you will need to upgrade to enable “Download and Debugging” support. You can download the VEXnet Key 2.0 Firmware Upgrade Utility here.
    • Download the “VEXnet Key 2.0 Firmware Upgrade Utility” and insert your VEXnet 2.0 key to any free USB port on your computer. Follow the instructions on the utility to update each key individually. All VEXnet 2.0 keys must be running the same version in order to function properly.
  • After updating your VEXnet 2.0 keys, you will need to update your VEX Cortex and VEX Game Controllers with Master Firmware Version 4.25 from inside of ROBOTC.
  • After updating the master firmware, you will also have to update the VEX Cortex with the latest ROBOTC firmware.

ROBOTC 4.50 —> 4.51 —> 4.52 Change Log:

New Features and Improvements:

  • Added support for simple mathematical expressions in numerical text boxes in Graphical.
  • Datalogging has been added for the VEX IQ platform.
  • Users can now log data from inside your program, with or without a timestamp.
  • Users can also configure motor, sensor and other values to be automatically polled at intervals as low as 10ms.
  • Users can view data in ROBOTC as it polled in and save to a .CSV file for additional analysis in a popular spreadsheet software.
  • You can use standard keyboard shortcuts to Select All, Copy, Cut and Paste in the Debugstream Window.
  • Natural Language Library Files have been enhanced for improved readability.
  • “Port with no Motor” has been added as an option for graphical blocks that use multiple motors – this will allow you to unselect a specific motor.
  • Graphical Copy and Paste has been improved to work better with comment blocks.
  • A flag (-SUPPRESS ) has been added to allow suppression of command line activation errors.
  • When compiling multiple files at once, the IDE will remain more responsive to user interaction.
  • A setMotorBrakeMode block has been added to Graphical, allowing motors to be set to either “float” or “brake”. This will allow motors to be setup as “free running”. This command can be found in “Expert” and above menu levels.
  • Additional programming samples have been added
  • User I2C commands for the Cortex has been implemented.
  • Users can now use custom I2C sensors within their programs – custom I2C commands are compatible with using the VEX Integrated Motor Encoders.
  • The list of loggable properties has been greatly trimmed down and sorted according to menu level. Static and irrelevant properties have been removed where appropriate.
  • Datalogging has been enabled for the VEX Cortex platform

General Bug Fixes:

  • ‘Trial’ indicator displays correctly, regardless of license combinations.
  • Missing function added to the Function Library descriptions
  • Fixed and improved “hover over” tool tip help descriptions inside of the Function Library.
  • Resolved issue where the bottom of the Graphical Library view would not be cleared properly when scrolling
  • Char arrays with “\0” are properly initialized.
  • Selection of options inside of a Graphical Block can be reverted by using “undo”.
  • Fix potential RVW file read issue from crashing ROBOTC.
  • Several float-related issues resolved:
    • Compiler incorrectly optimizes constant expressions with ‘float’ operands.
    • Formatted printing does not work with negative floats
  • Using nSemaphore.nOwningTask comparison no longer generates a compiler warning
  • Two enum issues related to overflowed values have been fixed.
  • Functions returning pointers no longer generate errors when used in Boolean logic expressions.
  • Values from arrays of pointers assigned to another pointer, no longer cause errors.
  • setMotorBrakeMode commands take immediate effect, rather than after the first motor speed command.
  • Closing a source file could cause am unhandled exception under certain conditions, this has been resolved.
  • Compiling multiple Graphical programs at once no longer generates an error that there is no code to compile.
  • Fixed an issue where the Global Variable Base Address was incorrectly displayed.
  • RVW Package Manager will only self-elevate if multiple level packs are being installed.
  • Numerous small visual enhancements and fixes.
  • Clearing a datalog series now clears the listbox properly.
  • The Datalog debug pane can now be opened in Basic menu level.
  • Changing Datalog source could lead to incorrect properties being shown, this has been fixed.
  • The UploadDatalog intrinsic is no longer exposed to the user.
  • Clicking download in the auto check for updates dialog did not work properly, this has been fixed.

VEX Bug Fixes: 

  • VEX IQ no longer crashes when using Ternary String Decisions
  • Users are now alerted when a VEX IQ program exceeds the max allowed compiled program file size.
  • Fixed issue where using playSoundFile on VEX cortex would generate a compiler error
  • Compile errors in sample programs for the VEX IQ Smart Radio messaging have been resolved.
  • Fixed an issue where a disconnected Ultrasonic Sensor was not returning -1 when disconnected from the VEX Cortex.
  • Motors dialog pane for VEX Cortex now shows default motor names, rather than port names.
  • An enum for the VEX IQ data path values instead of using raw numbers, has been added.
  • Prevent users from using sscanf with floats on the VEX IQ to avoid crashing the brain
  • Previously, setMotorTarget on the Cortex would not work correctly if the encoder had been reset to 0, this has been fixed.
  • On the Cortex, moveMotorTarget was not working as intended, this has been remedied.
  • Intrinsics to return the IME velocity values have been added.
  • IME velocity is now shown correctly in the motor debug window, for Cortex.
  • A bug with PID using Quad Encoders has been fixed.
  • bUseVexI2CEncoderVelocity has been obsoleted, it was not tied to any internal functionality.
