After a long and exhaustive search on the forums and googling around, i still dont understand why pio builds and compiles the whole marlin folder even when a single fullstop has been changed in any of the underlying files. It takes varying times from 5min - 20min which is soo painful coz i cant get any work done. soo frustrating so therefore am asking for your help.
This is the folder structure of my marlin folder in vscode.
Am compiling for an LPC1768 platform.
Below is what constitutes my platformio.ini file.
[platformio]
