I'm using this for such cases:

Code:
topline: 'top line updater sub
ofs=pos*16 'modify position offset
for x=0 to 15
i2cread sda, scl, adr, x+ofs, [y] 'write from eeprom
tline[x]=y 'write into array
next
lcdout $FE, $02 ' top row
for y=0 to 15
lcdout tline[y]
next
return
This is for top row and have similar for botton row.
