Re: [avr-gcc-list] Cont. Programming in eeprom in avrdude

[Sumeet Pal Singh]

hi 
i wish to keep constants in the eeprom. Actually the data is for maze
solver robot. We wish to keep some prodefined data in eeprom. the
eeprom storage and reading during run time can be easily done, but
before hand some programming in quick time becomes difficult. Changing
certain values 10 minutes before match becomes problem. 

Eric could you elaborate on formation of .eep(if possible with an example). I believe this is what i want. 
thanks
sps

Hello Summet,
what data do you want to programme in the EEPROM?
strings or some constants. The easiest will be to use
a simple assembler (popular ones being that of 8051
controller). Create a source code with your data, if
strings db "xyz" etc. assemble and link. This process
will not take more than 10 seconds and if you have a
batch file things will be easier. The output hex file
is ready to go into your eeprom!!! HTH.
