Compiling and Linking the Program
The most convenient way is to use µVision-51/251 for this purpose. A project
definition file named SAMPLE.PRJ contains all required settings and
automatically identifies all required files. Use ‘Open project’from the ‘Project’
menu to select this file. SAMPLE.PRJ can be found in the sub-directory RTX51
(for RTX-51) or RTX251 (for RTX-251) in the C51/C251 tools directory.
By use of the ‘Make: Build project’selection out of the ‘Project’menu the sample
program is compiled and linked in one step.
