Limitation

Please kindly keep in mind some limitation when using easyDSP as belows.

Common

1. Only little endian is supproted.
2. easyDSP uses the interrupt service routine for its communication to MCU.
Therefore if the allocated resource time for the interrupt service routine for easyDSP communication is limited due to the lack of resource, easyDSP could be not proplerly working.
3. Value at address operator (*) is supported to pointer variable to basic type only, and for C28x only. That is, not supported to for example, pointer to pointer, pointer to array and so on.
4. Arrow operator (->) is not supported.
5. Writing to 'bit field' type variable is not allowed.
6. Multi dimensional array is supported upto 10 dimension.

Limitation

Pleae check the limitation of easyDSP by MCU. o = supported, x = not supported.
Flash programming is not available in case the protection or security function is applied.
For details, please check the relevant menu for each MCU.
