I wish to implement a uVision Display DLL to display values from a structure within my C51 software. I have looked at App Note 144 which says, "the capabilities are not limited to real-time operating systems, every kind of status information, i.e. (sic) the file table structure of smart card operating systems can be displayed." However, the App Note & accompanying example code are entirely focussed on the RTXtiny kernel, and rely upon an in-depth understanding of RTXtiny. As I am not using RTXtiny, does anyone have a simple example for displaying status information from a C51 structure, or other tips which don't require inside knowledge of RTXtiny?
I compiled the example file of "Implementing Display DLLs for User-defined Output ", but when I use it to replace the default rtx51tiny.dll,it doesn't work! Is there any example showing how to implement a "Display DLL"? The APNT_144.PDF is too simple!
