10. Compiling a program with PICBASIC PRO
The P-Star is compatible with PICBASIC PRO, a BASIC language compiler from microEngineering Labs that
runs on Microsoft Windows and targets PIC microcontrollers. This section explains how to compile a program
and load it onto the P-Star using MicroCode Studio, the IDE that comes with PICBASIC PRO. PICBASIC PRO
is not free, but there is a trial version that you can try for a limited number of days before deciding whether to
purchase PICBASIC PRO [http://store.melabs.com/cat/PBP.html].
