Hi everyone, in my projects j often use the philips 87LPC764 (8051 derivative low pin count). The micro is good but it has only 4K of code memory, so j'm always searching methods to compact my code as much as possible. In one project j use some modules written in assembler, and since the total amout of code of that modules is less than 2K j tried to use AJMP and ACALL to save memory. Unfortunately the linker locates somewhere in memory the modules so j must use JMP and CALL to correct the situation. J used a little trick to correct it, in the project j loaded first the assembler modules and after the other. The linker seems to link modules in order and this trick functions good, but my answer is : How to get the modules located in low 2K of memory using a more elegant and/or fast method??? Thanks in advance. Sorry for the long post!!!!!
