Migration f28335->f28346

Hello,

I'm currently using the f28335 ezdsp evaluation board developing some control application with the target support package (Matlab/Simulink). However, I'm afraid the f28335 is not fast enough for my application. Is migration to the f28346 possible without having to start completely from the beginning (e.g. changing only ADC-related parts)?

    Other than the ADC, I think the biggest issue that you may run into is that 346 has no onboard flash so your code will have to be stored somewhere else.

    Hi Thomas,

    check Matlab/Simulink if they have support for external ADC (maybe even for the ADC present on controlcard) or at least support for external memory interface (XINTF). If they have support for XINTF they probably have support for XINTF for 28335 also, so you could check right away how this works.

    Are you sure that 28346 will be fast enough? What is your bottleneck in current application?
