Larger EEPROM supported?

by **mfagan** » Wed May 30, 2007 1:07 am

Hi,

I am looking at larger eeproms from mouser and wanted to know if they are supported by the kit and software (for PC)

http://www.mouser.com/search/ProductDet ... C256-I%2fP (256kb)
http://www.mouser.com/search/ProductDet ... C640-I%2fP (64kb)

Thanks!
Mike

They will not work unless you modify both software and firmware. I am assuming (without looking) pin and function compatability with the eeproms that already exist.

its true, they dont work right now, although one day ill finally make it so it does...

I looked at the firmware and it looks like it will support the 64KB chip unmodified since it already uses 16bit addresses.

It looks like the only modification is to the software to probe for memory larger than 4x.

Unless I entirely missed something.

yup thats pretty much it

Does this translate into more frames of animation? Because that would be great.

I have updated the source file to support larger eeproms but I need to test it.
Is there any docs/links about setting up the development env for windows?

its called "mingw" there is some terrible documentation about it online

if you send me just the changes ill add it to the next revision which is going to be very soon (like 2 weeks)

Having more than 4 frames would be awesome. Is it possible to have the 64KB chip for sale (or an option) with the kit?

by **adafruit** » Thu Mar 06, 2008 5:26 pm

current software is tested with up to 16 frames (16KB/128Kbit), but not lots of testing
