I have some legacy code that was built with C51 v5.02.
We have issues with the parallel-port dongle and I am trying to use the new version of the C51 compiler (v9.55).
Assembly (A51) and compilation (C511) seems to work. For the linker (L51) I have found that the new program is called LX51 and has some different command line syntax.
So I now have similar to:
LX51 [obj files] TO [output file) RS(256) DL DP DS OVERLAY(SEND_SHORTRESPONSE ! *, LOG_TXRX ! *, READ_FLOWSENSOR ! *, PUTCHAR ! *)
But it complains about invalid syntax. If I remove the RS(256) DL DP DS directives, it will link, but I am not sure it will generate the correct output.
I have tried to figure out what this directives used to do and what the equivalents are in the version, but so far no luck.
Can anybody help with this issue?
