Lib compile issue.

[larryl79]

example code #vscode #platformio #esp32 devkit

I've edited your LCDML_001_liquidCrystal.ino example for platformio (renamed to main.cpp, and included rest of the files as .h after constructor).

src dir: LCDML_condition.h LCDML_control.h LCDML_display_dynFunction.h LCDML_display_menu.h LCDML_display_menuFunction.h main.cpp

main.cpp (edited part): `// // Objects // LCDMenuLib2_menu LCDML_0 (255, 0, 0, NULL, NULL); // root menu element (do not change) LCDMenuLib2 LCDML(LCDML_0, _LCDML_DISP_rows-_LCDML_DSIP_use_header, _LCDML_DISP_cols, lcdml_menu_display, lcdml_menu_clear, lcdml_menu_control);

// // LCDML MENU/DISP // `

(for another try I downloaded the latest lib from github, and overwritten in the libs dir. It's same issue) when I try compile, I got error messages for the lib itself only.
