Hi i want to interface a propeller to the 2.8 oled from 4D systems.
I have my test setup here, but now i am facing a funny problem.

I have a 2 gig SD card what supposed to work with the oled.
But i found out the card needs to be formated in FAT16 with 16kb cluster size.

Since windows cant format it tis way and only takes 30 minutes to tell me after windows tried it.

So is there a way to format a SD card from a prop ???

Best regards Oliver

    Did you think about creating a smaller partition... like a 512 M one ? or a 1 GByte ? With 2GB the only way are 32 kbytes clusters. In linux I'd use fdisk, in winblows it may also help... or that disk utility that is hidden somewhere.

    Hi Oliver,
    Maybe try this tool:
    HP USB Disk Storage Format Tool

    with a 1Gb partition for now

    i got it fixed, it was a bug in the firmware, and a bad tutorial on it, so i had to figure it out the hard way,
    It works now with 32 k cluster size on the 2 gig ..

    And i also have made some good progress on the display, looks almost like a clone from the x6.
    I can send you a picture to the blog.

    Best regards Oliver
