Which Is Better!!! | M68HC11 | EmbeddedRelated.com

i am doing my final year project using expanded mode configuration.. i am using an additional 64KB EEPROM(28C64) with MC68HC11 E1.. i wanna know which is the better way to program the eeprom.. my friend has advised me to use Jbug11... i talked to my lecturer and he advised to directly load the program inside the eeprom... so,which is better and easy... plz help me... should i use serial communication RS232 or directly load the program inside the eeprom and then coonect it with MC68HC11.. and can anyone suggest which software can i use to program 28C64 EEPROM...

Unfortunately, not every utility is right for every hardware configuration, and there are 'infinite' such configurations. JBug11 should do IF you can tweak it to your hardware (or if it happens to directly support your hardware). This means you might have to modify the 'talker' provided. > i talked to my lecturer and he advised to directly load the program > inside the eeprom... Forgive your lecturer for wanting to torment you like this. If you program the EEPROM separately, you'll have to plug/unplug the chip from its socket for every little change in your code. Do YOU want to do that? (I can think of better ways to waste time.) > should i use serial communication RS232 Yes, use the HC11's bootmode and have the EEPROM always connected. Switch to bootmode to program it (with whatever software works for you), then switch to normal mode for running your code. > or directly load the program inside the eeprom and then coonect it > with MC68HC11.. It's your life... > and can anyone suggest which software can i use to program 28C64 > EEPROM... There are various breeds of EEPROM. Some use proprietary algorithms, others are written exactly like RAM, etc. So, whatever software you use, it has to be compatible with your memory chip. If all else fails, you could always write your own little 'talker' that will load in S19 records from the RS232 and program your EEPROM using whatever algorithm needed. (And you can be proud of having built an EEPROM programmer in the process.)
