Remote control of MPC5553 microcontroller with C

  • Hello,

    We are using a NXP MPC5553 microcontroller and we need to:
    -set breakpoints
    -run to breakpoints
    -read variable values
    -write variable values
    -read register values
    -write register values

    Using the C programming language. We saw the UNITPPCNEXUS dll (

    Is this the correct product to do what we're looking into?

    I just wanted to confirm before we purchased. Any further information would be greatly appreciated.



  • Greetings,

    You are correct that the UNIT PPCNEXUS DLL can be used to run, step, set breakpoint, read/write variables and registers. It can also load RAM binaries. But it there is no support for flash programming.

    • Thank you for the quick reply. Is there a product that supports flash programming through a C API and works in tandem with UNITPPCNEXUS?

  • Greetings,

    We have our PROG software you can use to flash program, but is not a C code API. Only the UNIT library has an API.
