Hello pascal carreweyn ,
- About the development DALI , I recommend you first have a look at "DALI getting started guide"
Scalable Entry Level 32-bit Microcontroller (MCU) based on Arm Cortex-M0 Cores|NXP

- " I tryed to make a new project with an LPC1124 but there i got stuck on some compiling problems which i don't understand. I'm not experienced with the MCUXpresso, so this makes it a bit hard to do for me."
About compiling error, you can share your project, then I can help you check it .
Hope it helps,
Have a great day,
TIC
