I have a little question about the compatibility between the C166-Compiler versions : * 3.05 (uVision 1.24) and * 4.27 (uVision 2.38) - the actually version ============================================= => I have a SW-Product which contain 2 SW-Projects ('A' and 'B') 'A' communicate with 'B' through a SW-API : * Global variables * Pointer to functions (with different parameters) Both SW-Projects ('A' and 'B') have been compiled with the old Compiler-Version. { I can download the both SW-Projects separately } ============================================= ? Can I use the new C166-Compiler version and re-compile only one of the SW-Project ( 'A' or 'B' ) ? The generated code (Function calls [ the used registers ] ) is compatible ? A lot of thanks in advance, Steffen
