I have an application developed with an old version. Will it compile properly with the latest version?

| | | | | | | | | |

Yes. If you have written your program according to our recommended practices in the product documentation, upgrading should be seamless. All Byte Craft Limited Code Development Systems have backward compatibility with previous language constructs.

Please note:

  • Improvements in the compiler can alter the generated code; this may impact your testing.
  • Device header files may change between versions. If you've written customized device header files, they may require some revision. Simply examine the stock headers that we ship with the product.

C6805 - Filling Unused ROM

It is possible to fill an area of the 6805's ROM with a particular value and set an interrupt vector to point to the initialization at the start of the program which comes before the main() function. This method can easily be extended to use any value or series of values.
