Hello,everyone. just like the title. I write C code like this: ------------------------------------------------------------------------------------------ #include<pic16f887.h> unsigned char a[4] = {0x12, 0x13, 0x14, 0x15}; int main() { PORTA = a[2]; return 0; } ------------------------------------------------------------------------------------------- the generated asmbler file is: ------------------------------------------------------------------------------------------- ID_a_0 idata _a db 0x12 db 0x13 db 0x14 db 0x15 STARTUP code 0x0000 nop pagesel __sdcc_gsinit_startup goto __sdcc_gsinit_startup code_a code _main BANKSEL _a MOVF (_a + 2),W BANKSEL _PORTA MOVWF _PORTA ; .line 1806; "a.c" return 0; MOVLW 0x00 MOVWF STK00 MOVLW 0x00 RETURN ; exit point of _main end -------------------------------------------------------------------------------in the manual of gputils for the directive IDATA have this "Data memory is alllocated and the initialization data is placed in ROM,The user must provide the code to load the data into memory"so , just like the title can sdcc generate code which can load value from ROM(placed for idata directive) to RAM in startup?if have Where is the source code doing this LOAD? if not ,How can i do this? Another, in SDCC PIC14 the *pic16f887.lib* doing what? and how it come from? how can i compile to get it by myself? What does it contain?
