Hello!

Given:

1 - Ubuntu 18.04 LTS

2 - CCS 9.2

3 - processor_sdk_rtos_am57xx_6_00_00_07

4 - pdk_am57xx_1_0_15

5 - JTAG emulator XDS220 Spectrum Digital

6 - Project - vps_captureVipExample_idkAM572x_armExampleProject

I have an ar 0134 sensor. I need to change the values of the RGB colors in the registers. We know the addresses of the RGB registers. Namely: green1 gain, blue gain, red gain and green2 gain. The transfer of register values is via the I2C interface. Question: how can register values be changed in the project code vps_captureVipExample_idkAM572x_armExampleProject?

Thanks!

Okay, I modified part of the project code vps_captureVipExample_idkAM572x_armExampleProject:

static Int32 CaptApp_createVidDec(CaptApp_Obj     *appObj,
                                  CaptApp_InstObj *instObj)
{
    Int32  retVal;
    UInt32 decInstId, decI2cInstId, decI2cAddr;
    Vps_CaptCreateParams  *pVipCreatePrms;
    Bsp_VidDecChipIdParams decChipIdPrms;
    Bsp_VidDecChipIdStatus decChipIdStatus;
    Bsp_VidDecCreateStatus decCreateStatus;

    pVipCreatePrms = &instObj->createPrms;

    decInstId = Bsp_boardGetVideoDeviceInstId(
            instObj->decDrvId,
            FVID2_VPS_CAPT_VID_DRV,
            instObj->instId);
    decI2cInstId = Bsp_boardGetVideoDeviceI2cInstId(
            instObj->decDrvId,
            FVID2_VPS_CAPT_VID_DRV,
            instObj->instId);
    decI2cAddr = Bsp_boardGetVideoDeviceI2cAddr(
            instObj->decDrvId,
            FVID2_VPS_CAPT_VID_DRV,
            instObj->instId);

    /* Power on video decoder */
    retVal = Bsp_boardPowerOnDevice(instObj->decDrvId, decInstId, TRUE);
    if (FVID2_SOK != retVal)
    {
        UART_printf("Device power-on failed\n");
    }
    if (FVID2_SOK == retVal)
    {
        /* select video decoder at board level mux */
        retVal = Bsp_boardSelectDevice(instObj->decDrvId, decInstId);
        if (FVID2_SOK != retVal)
        {

        }
    }

        }
    }

    if (FVID2_SOK == retVal)
    {
        /* Select specific mode */
        retVal = Bsp_boardSelectMode(
                instObj->decDrvId,
                decInstId,
                appObj->testPrms.boardMode);
        if (FVID2_SOK != retVal)

        }
    }

    if (FVID2_SOK == retVal)

Sorry, I accidentally clicked. The question remains. Question: how can register values be changed in the project code vps_captureVipExample_idkAM572x_armExampleProject?

Yan,

It appears you're on the right track. Here's what I see in the AR1034 datasheet:

I'm not clear on whether the green1 gain, etc. registers are 8 or 16 bits. For 16 bit registers, I'd use Bsp_deviceWrite16() like you already have. For 8-bit registers, I'd try using Bsp_deviceWrite_Custom_16A8D().

Do you see any activity on the I2C bus?

Regards,
Frank
