Hi, thank you for your reply! As far as I can see, ProcessorExpert is used in the linked tutorial.
It seems to me that PE does not support LPC microcontrollers:
Processor Expert software covers Our S08/RS08, S12(X), ColdFire®. ColdFire+, Kinetis®, DSC 56800/E, QorIQ® and some other Power Architecture® processors.

I am using the MCUXpresso IDE.
Do you have any other good tip for me please?
Thank you for your time!!!
