ÈI've just started using MPLAB 3.22. I'm having problems with creating Èand opening projects. Whenever I open a project (project file created Èwith 3.22), the primary file is not automatically opened for editing and ÈI get a dialog box telling me "Error Opening HEX File". In MPLAB: Projekt>Add/Modify Compiler Hex File INHX8M /ainhx8m INHX8S /ainhx8s INHX32 /ainhx32 Write this, and it will work. Good Luck //Lars Johansson Stockholm, Sweden
