    eww...

    Hmm... According to the Label on your PIC, there should be MIOS on it. But if you have MIOS on your PIC, there should be a message saying "Ready." on the LCD, which is not appearing here.

    There are two things I would do for troubleshooting in this case:

    1. Check the wiring of your LCD. Compare the CORE-schematics with the pinout of your LCD.

    Try to contact the supplier of the LCD and ask him what he can say about the strange typo in the datasheet.

    2. Connect the Core to your PC (MIDI), start MIOS Studio and check if your Core is sending any Upload-Requests at startup. Then Check if there is a MIOS-Version installed on the Core.

    hope that helps

    edit: 4-bit mode is a good point, frailn. I haven't thought of that.

  2. seems all fine untill now.

    The black row is completely normal as long as there is no MIOS on the PIC.

    You'll have to connect the CORE with your PC (via MIDI) and upload the most recent MIOS-Version with MiosStudio (uCApps -> Downloads).

  3. 1. it seems like i have two [DB2] and no [DB4]... what am i to do about this? do i connection the 2nd [DB2] to the [D4] on the core or do i not connect it at all?

    I guess Pin11 is a Typo. I think it should read DB4 there. Just try it, you won't destroy anything.

    2. on there core i read [b+ led] and [b- led] and on my LCD i read [LED A] and [LED K] i assume these are the once to be connected, but how do i know witch one on my LCD is the + and -?

    A[node] -> [+]

    K/C[athode] -> [-]

    3. just a little safety things.. this is the back side of my LCD and i just wanted to be sure i read it right according to the data sheet,, can anyone confirm my read?

    The Pins 1,2 and 15 are indicated on the LCD-PCB.

    Upper Row [l. to r.]:  1-3-5-7-9-11-13-15

    Lower Row [l. to r.]:  2-4-6-8-10-12-14-16
