I am interested in moving my existing product from older LPC parts to the LPC546xx family. My current code base is built on top of the LPCOpen code and runs on a number of different LPC processors due to the common API provided by the LPCOpen packages and builds quite happily with a custom build environment.
LPCOpen is mentioned in the LPC546xx User manual (UM10912) chapter 40 - where can I download this from?
I note that there is a MCUXpresso SDK available, but it is structured entirely differently and would require considerable work to port my application to it. If that was required, I think I would start considering my options for different vendors parts.
