Other Parts Discussed in Thread: DS90UB928QEVM, ALP

Hi 

I have a DS90UB928QEVM and a DS90UB925QSEVB board. I would like to use them on windows7 but I didin't find any driver. 

Is there any possibility to resolve this prolblem or I must use virtual machine with windows xp ?

Best regards,

Gergo

    Hi,

    Instructions to install the Windows 7 x64 drivers are contained in the Help menu. Go to Help > ALP Help > Installation.

    Hi,

    I have two question again with this device (DS90UB925QSEVB). I didn't fint any manual about how I can use external video signal. 

    In the  " snls407d.pdf " there are R[7:0], G[7:0], B[7:0], HS, VS, DE, PCLK PDB lines, but I don't know what kind of signal should I use.

    Is there any device or IC  which  generate these signals from for example a simple VGA?

    Second question: I only find two command for scripting in the help of ALP

    • board.ReadI2C(devAddr, regIndex, regLength= 1) 
    • board.WriteI2C(devAddr, regIndex, regVal)

    and the user manual doesn't consist them ("Usage is not described in this document."). Could you write me somebody where can I find documentum which contains usage of scripting?

    Thanks a lot for help,

    Best regards.

    The 925 R/G/B and control signals are LVCMOS data inputs on the J5 connector. This is described in section 2.4 of the EVM user guide -- http://www.ti.com/lit/pdf/snlu113

    Typical equipment that may be used to generate signals for these inputs include:

    1) Digital Video Source – for generation of specific display timing such as Digital Video Processor or Graphics Controller with digital RGB (LVCMOS) output.

    2) Video generator

    3) Any other signal generator or stimulus that generates the correct input levels as specified in the datasheet

    For your second question, the primary scripting I2C commands are board.ReadI2C for I2C reads and board.WriteI2C for I2C writes. Example code is included in ALP Help under: Using the Application -> Tools -> System Scripting
