EEPROM and Propeller
Somnium
Posts: 46
I'm working on a project and just need some input and help. I'm planning on recording a short clip, mayb 10-20 sec. worth, and was wondering if I could store that onto the EEROM that is already present on the Prop Propeller Stick. If not around how much space would I need, and possibly some links to where I could buy them. Thanks.

If you have the USB PropStick, you'll have to add an external EEPROM or unsolder the existing SOIC package and substitute a larger capacity one.
The problem with trying to store data into the existing 32K EEPROM is that downloading any program to the PropStick with the Propeller Tool will erase the data that's there.
Another alternative is to include your binary data in the program being loading into the EEPROM by the Propeller Tool.· Check out the binary file include statement in the SPIN part of the Propeller Manual.
However I do have some 24LC256 EEPROM's to play with.
Can I connect an additional 24LC256 EEPROM in parallel with the existing EEPROM on the PropStick USB, and simply connect A0 thru a 10K resistor to 3.3V?
Can the Propeller Tool program the additional EEPROM?
Use the I2C library object to read and write to the additional EEPROM?
In that way it would behave much the same as a larger EEPROM.
You might read the 24lc256 PDF and compare to the 24lc512 PDF so that the addressing is seamless.
