Recently I have a project based on LPC845, so I do some tests on the LPCXpresso845MAX. I download LPC845 Example Code Bundle IAR from website, which was works well. But, if I want to use on my own project, some drivers were need to modify. So I try to use MCUXpresso Software Development Kit (SDK) ,which is very efficient. But when I compared with them, there are many difference, such as some definitions of some IRQs in the header file. My question is which way is preferred? Do you have any good suggestions?
