Display on the LCD through VGA interface

Other Parts Discussed in Thread: CCSTUDIO

Hi,

I've bought the 5515EVM + Digital Stethoscope Front-End Module and want to develop a project, which need to display the outcomes(text and waveform) to the LCD through VGA interface. So I want to know if there is a way which is not too complicated?

    Hi,

    Do you mean that H sync and V sync plus data lines? If then, C5515 can not support VGA interfave.

    Hi Peter,

    I want to develop an identification system based on heart sound signal, the LCD on the board is not big enough, so I plans to display the outcomes on LCD (like 800*600) with  a VGA interface(15 pins), it can be achieved by MCU and FPGA, so I 'm wondering if it can be done on 5515 EVM board, through UART, or SPI...? If it's impossible, I'll transfer the outcomes to PC through UART and let the application do it.

    I don't have experience, so I 'm studying the codes of the provided STETHSystem.pjt. I have a problem, I can build the project with CCS3.3 and burn the program(.bin) with CCS4.1, but I can't open the project with CCS4.1(you told me last week) and can't  link the board with CCS3.3, because the emulator is not right, so I could not debug on-line.What can I do to the CCS3.3 to make it work? Are there some files to be added?

    Best Regards,

    Gao Jiao

    Hi Hyun,

    Yes it's the 15 pins "Hsync, Vsync, RGB" data lines, if it's impossible I'll find other ways, thank you!

    Hi Jiao,

    The LCD module in the C5515/05 only support asynchronous interface. If your LCD interface requires synchronous interface (like pixel clock, Hsync, Vsync, etc), then it won't be supported. However, if you are OK, you can put FPGA or MCU between the C5515/05 and the VGA.

    For the stethoscope project, we should be able to convert it to the CCS4 project but it will take some time. What emulator are you using? The C5515 EVM has an on-board emulator, it should work.

    Hi Peter,

    The emulator is Spectrum Digital TMS320C5510 DSK, I can emulator with CCS4.1. I want to use the CCS3.3 just because the STETHSystem project can't be opened with CCS4.4. But another problem is that I can't connect the emulator with CCS3.3 because there is no available boards for the emulator. So I downloaded the emulator driver for ccs3.3 from http://support.spectrumdigital.com/ccs33/. After the installation, I ran the Setup CCStudio v3.3 and it appeared:

    I ignored the error and selected the C5510 DSK-USB boards and Save&Quit, then debug-->connect,  it appeared:

    Error connecting to the target:

    Error 0x80000200/-1137

    Fatal Error during: OCS, 

    It appears that the target is being held in reset.  This may be

    due to Wait-In-Reset (WIR) configuration set by the EMU0=0

    and EMU1=1 pin settings.  If this is the case, DISCONNECT

    all CONNECTED devices including icepick and then select

    RETRY to clear the WIR configuration.

    If this is a multi-core system, the master CPU may not be

    releasing the DSP/MCU from reset.  Please check your

    configuration in CC_setup and/or your GEL file to ensure that

    nothing is blocking the DSP/MCU from being released from reset

    Sequence ID: 0

    Error Code: -1137

    Error Class: 0x80000200

    I/O Port = 540

    Board Name: DSK5510

    Cpu Name: DSP_C55xx

    Abort: Close Code Composer Studio.

    Retry: Try to connect to the target again.

    Cancel: Remain disconnected from the target

    Diagnostic: Run diagnostic utility.

     

    I installed CCS3.3 and emulator driver in another PC, it's the same problem.

    Can you help me with this?

    Regards,

    Gao Jiao
