#190396 - Using SDCC... Responding to: ???'s previous message |
Placing a variable at a fixed location is best done with the relevant toolchain C language extension. In SDCC you can use the following:
__code __at (0x0ff0) unsigned char ID = MY_CODE_IDENT; As others have posted, you cannot write to code ROM in your application, you can only set the ROM at compile time. If you really want to write a value that persists through a power cycle, you will need to store it in EEPROM, not code ROM (the clue is in the name). |
