How to write data to the EEPROM?

lyassa

I have the "Propeller Education Kit". How can I write data back to the EEPROM? Do I need any parts other than what came with the Education kit?
Thanks in advance for your answer.

The EEPROM that came with the Propeller is used to store Spin programs and you don't need any additional hardware to do this.

Just follow the instructions in your lessons and you will likely find you have everything as Parallax tries very hard to provide complete kits for beginners.

Sometimes examining each function is a good way to see what's going on.

If you want to play with the EEPROM from a command line, perhaps check out propforth

The word

saveforth

writes the current RAM imange back to EEPROM

Also, the source code file fs.f implements an EEPROM in the upper area above the standard 32k image on 64K or larger EEPROM.

This allow one to see how the commands are set up, and the individual commands to perform each function, and they can be run from the command line.

The lowest level word are implemented in assembler, so you can see exactly what they do, and are strung together as forth words like charms on a bracelet.
