Jo, die Fehlerabfrage könnte man rauslöschen, werd ich bei der nächsten Version machen.

I have 2 questions there once. . 1 can I access sequentially with the adm-fat.spin to a file or streaming is just possible. . 2 How can I read or write geziehlt a Sector on the SD card with the adm-fat.spin.

Hi Andrio,

I don't know whether I understand what you are asking for.

ad 1.

You access a file sequentially by sdgetc/sdputc from reg-ios.spin which calls readCharacter/writeCharacter in adm-fat.spin.

What do you mean with streaming? Using one cog in Regnatix for accessing Administra's SD card functions and another cog in Regnatix to do your desired function? - No Problem I assume. But explain it a bit more in detail what you intend to do.

ad 2.

To access a random sector on the SD card you would have to make readWriteBlock from adm-fat.spin accessible to Regnatix. The other functions for reading/writing bytes operate on the currently open file. Look at readWriteCurrentSector in adm-fat to see how to compute the address for readWriteBlock. But of course accessing a file system this way may well destroy it.

Best Regards,

Dietmar
