Hi, Does anyone know how to create a user class for the HCONST memory type using the c251 compiler similar to creating one for the ECODE memory type: #pragma userclass (ucode = foo). The above would create the user class ECODE_FOO I want to do this: #pragma userclass (hconst = foo) to create the user class HCONST_FOO so I can position the constants in the file foo.c in an absolute memory address range at link time. However, hconst does not seem to be a memory type that the C251 compiler can assign a user class to. Any help would be greatly appreciated. Thanks, Trevor.
Here is how I did it with C251 v2.14. 1. Use X-Tiny memory model, constants are put to NCONST memory class. 2. In program module put desired constants to HCONST memory class by declaring them as following example: static uchar const far SOP_String[] = {0x15,0x08,0x08,0x00,0x00,0x30,0x00}; 3. You can access this constants from the linker L251 as ?HC?MODULE (where MODULE is the name of your program module) and locate it to an absolute address.
