Procedures for Developing New Program
- Create a new project file

- Press the [Add] button.
- Type "cfg32r" in the "Tool Name" text box.
- Type the name of the executable file of the configurator in full path in the "File Path" text box.
Example: C:\MTOOL\BIN\CFG32R.EXE
- Give the "-m" option to the "Parameters".
When the name of the configuration file is given, enter the name at the same time.
- Type environment variable "LIB32R" and "GCC_EXEC_PREFIX" in the "Environment" text box.
Example of typing LIB32R:
