Part Number: HALCOGEN
I am interested in SCI in multi-buffer mode. I tried find answer/example in HALCoGen, newest version. With no luck. Then I find example on this forum (.zip).
By comparison two files (one from .zip demo and 2nd generated by HALCoGen), there is big difference in work around multi-buffer SCI.
So I must ask, why the multi-buffer functionality is missing (in newer versions) and why I find two indentically signed versions of file (origin TI) not identical?
Thank You
