Differences Between µVision4 and C

There are a number of differences between expressions in µVision4 and expressions in the C programming language:

  • µVision4 does not differentiate between uppercase and lowercase characters for symbolic names and command names.
  • µVision4 does not support converting an expression to a typed pointer like char * or int *. Pointer types are obtained from the symbol information in the target program. They cannot be created.
  • Function calls entered in the µVision4 Command Window. You cannot invoke functions in your target from the command line.
  • µVision4 does not support structure assignments.
