  • Copy screen to Memory card

    Hello,

    I can't use the function function "Copy Screen to Memory Card @C" on a ĀµOLED-160-GMD1.
    The function @w and @W are OK. With this fonctions, data are writes on MicroSD 64M and the reading of these data confirms it to me.

    Have an idea?

    Hello,

    Can you give some details ?
    Without more information it's difficult to know what's happening

    What is the command you are issuing ?
    What's the answer of the module ?
    Did you set the appropriate address for the command ?

      Hello,

      After the writing in the memory card with the function "@C" after
      having written some characters ("T"), the answer is well ACK, but by
      reading in the same sector (00 00 00) with the function "@R", all is
      to 00.

        Hello,

        After the writing in the memory card with the function "@C" after
        having written some characters ("T"), the answer is well ACK, but by
        reading in the same sector (00 00 00) with the function "@R", all is
        to 00.
        So you've written some formatted text on the screen & want to get a copy of that screen to the memory card.

        The function @C copies part of the screen to the memory card at an specified address, and @R reads only one sector.

        So if the first pixel stored is black I think it's normal to read 00. Just a fool-proof question: have you tried to read the following sector ?
        You can try to send "E" followed by "@I" with the same address to see if it actually displays the screen you expected.

        I don't have the modules at hand yet, so I can't say more. If you believe it is a faulty module you should talk to Atilla.

          There was actually a bug related to screen copy to card function along with a few others. These have now been fixed and the latest PmmC file has been released. All PmmC related matters are here:
