Hi,

I'm regarding a project for a HMI + communications. I do not want to use BGA components and keep all on a two layer board, so the only single chip solution I found is the all-in-one LPC2478. Initial idea for GUI is uCLinux + Qt4, but can this ARM7 handle such a thing? I'm talking about QVGA or 480x272 screens and controlling ethernet, USB and RS232/RS485. Some advice??

Thanks,

Oscar

Hi Oscar,

To answer your question, "Yes". This ARM7 can handle this.

However, if your project is anything like projects I work on, it will most likely have "feature creep", which means you may run out of processing power, after management and marketing add everything they can think of to the requirements specification (eventually they will).

I have purchased the development kit for the LPC2478 from FDI, and have found it to be very capable of performing everything on your list.

I also have purchased the LPC1788 development kit, which has the Cortex-M3 processor, and is faster than the LPC2478 ARM7.

I believe the two parts are about the same price, and I believe the LPC1788 will be available in production quantities very soon (don't know for sure - waiting on a response from Gene).

I hope this helps you,

Dave
