The ROBOTC Development Team is excited to make our latest update available to you, ROBOTC for VEX Robotics 4.56. This is primarily a maintenance release which contains many stability fixes. Keep reading for a full list of changes and improvements below.

Updates for all robot platforms:

  • When saving a C source file, you can now opt to keep a backup of the previous version of the file. This behavior can be enabled through the preferences.
  • Under certain conditions, semaphores could be given to a task that had not unlocked it. This has been corrected.
  • Previously, the compiler would count both prototypes and actual function implementations separately, reducing the number of functions available to you. This has been corrected.

Updates specific to VEX IQ:

  • The display would incorrectly show that it the debugger was being used, when disconnected from the PC.
  • There was a mismatch between the amount of available variable memory. This could lead to unpredictable results due to stack corruption with very large programs. The amount has been corrected. Most users will be unaffected by this change. Users with programs that use a large amount of variables, should verify their programs still compile.
  • Support for future VEX IQ firmware changes.
