Larger EEPROM supported?

Post by mfagan »

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.

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.

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?

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

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