#159320 - Different micros Responding to: ???'s previous message |
"I also use the upper limit of the flash for a little bit of "EEPROM" but this upper limit changes dependant on the processor type."
How about do a write then a read of the highest location, and then, depending on the result, identify the chip? Something like:
UpperAddr = HIGH_FLASH_ADDR;
*UpperAddr = Info;
Pause(); /* If needed for FLASH to program itself */
if(*UpperAddr == Info)
{
Micro = TypeA;
}else{
UpperAddr = LOW_FLASH_ADDR;
*UpperAddr = Info;
Micro = TypeB;
}
