How to use 2*32kb Eeprom?

Recommended Posts

I want to connect two 24LC256 for my Sequencer V2.0. I connected the two Eeproms like described in the circuid diagramm (Schematic for multiple bankstick setup):

http://www.ucapps.de/mbhp_bankstick.html

Eeprom1 is A0 Eeprom2 is A1

Then I modified the 'main.asm':

#define DEFAULT_BANKSTICK_PATTERN_CS 0

#define DEFAULT_BANKSTICK_SONG_CS 1

Pattern save is working, Song is still NOT working...

Are there other files or definitions to change?

Thanks for any help...

I guess that you are using the vintage setup, so possibly setup_mbseq_vintage.syx?

This would mean that you have to change setup_mbseq_vintage.asm, and you have to assemble this file instead of main.asm

Ok, I found the error: it doesn't work with two 32k BankSticks since there is a test which ensures that a 64k BankStick is connected before formating the song partition. This function should not be called on two different 32k BankSticks of course.

I tested it with two 24LC512 - and this test passed, therefore I didn't know about this issue.

However, you will find a patch under http://www.ucapps.de/tmp/mbseq_v2_0_bs_fix.zip - it will be part of the next release.

Best Regards, Thorsten.
