In the "UCD3138 Monitoring and Communications Programmer’s Manual" there is the following sentence: "All C code references in this document use standard TI header files, provided as part of the UCD3138 EVM (UCD3138PFCEVM-026, UCD3138LLCEVM-028 etc) reference firmware." I have bought UCD3138LLC-028, but I didn't get any software. Where can I find the C code mentioned above?
