[VistaCube] Quick Stand-Alone Porting Guide.

This post describes how to port the Vista Cube™ for RDCx00/RDP Flash Image download feature in stand-alone application, such as a firmware for MCU.

We assume that our stand-alone porting environment is on Win10 x64  and target products are RDC200/RDP550F.  (This demo project is a Visual Studio console project and it is located in $VISTA_CUBE_PATH\example\mcu_example\)

!! To try this demo, Vista Studio™ and RAON uDisplay EVB be used.

— In order to migrate Vista Cube™ download function into customer MCU platform, MCU compiler IDE and MCU I2C function should be used instead of we used Visual Studio and EVB respectively.

Take the following steps.

1. Download Vista Cube™.
   • You can find it on our dev-site.
   • Extract this zip file with a password (If you don’t know the password, please contact us).
2. Prepare your target build system with Vista Cube™.
   • Add include path :
     • -I$VISTA_CUBE_PATH\src\libvc\core\rdc200\
     • -I$VISTA_CUBE_PATH\src\libvc\include\
     • -I$YOUR_I2C_INTERFACE_HEADER_PATH\  (if need)
     • 
   • Add library path :
     • -L$YOUR_I2C_INTERFACE_LIB_PATH\  (if need)
     • 
   • Add name of library :
     • -l$YOUR_I2C_INTERFACE_FILE_PATH  (if need)
     • 
   • Specify library loading path (if need)
     • Copy SiLab_USB\SiUSBXp.dll and USBLibrary.dll in $VISTA_CUBE_PATH\src\test\windows\ to $VISTA_CUBE_PATH\example\mcu_example\
3. Connect your i2c interface to Vista Cube™.
   • You should implement the following i2c wrapping functions in $VISTA_CUBE_PATH/src/libvc/port/rti_vc_devif.c (Refer to Capter 2.3 Device interface Services in VistaCube_User_Guid_RDC200.pdf for details).
     • rtiVC_InitDevice();
     • rtiVC_OpenDevice();
     • rtiVC_ReadDevice(…);
     • rtiVC_WriteDevice(…);
     • rtiVC_ReadBurstDeviceExt(…);
     • rtiVC_WriteBurstDeviceExt(…);
     • rtiVC_CloseDevice();
     • rtiVC_DeinitDevice();
   • Check if the following functions are activated or not in $VISTA_CUBE_PATH/example/mcu_example/rdc200_dload.c ( these functions are required for normal panels booting)
     • rdc200_setup_firmware_data(…);
     • rdc200_setup_fw_cfg_data(…);
     • rdc200_setup_rdc_init_data(…);
     • rdc200_setup_rdp_init_data(…);
     • rdc200_setup_gamma_data(…);
     • rdc200_setup_bmp_data(…);
     •  
   • Check I2C SlaveAddress (It depends on your target system configuration)
     • RDC slave address : define it in your side. (e.g. #define RDC_I2C_SLAVE_ADDR    0x44 )
     • RDP slave address : #define _CFG_RDP_SLAVE_ADDR    0x39 in $VISTA_CUBE_PATH/src/libvc/include/rti_vc_config.h
4. Copy and Paste the latest init values to Vista Cube™ code inside.
   • Download an init file ( RDC100 init file / RDC200 init file) in according to your target.
   • Download VisualStudio™ on our dev-site( it is also password protected).
   • Power on RAON uDiaplay EVB and connect your host computer via USB and then execute Vista  Studio™. (If it is first time, board configuration wizard will be appear)
   • Burn the latest init files  into Flash via Flash burning function ( you can find this function on Toolbar menu of Vista Studio™)
     • Select $RDC200_INIT_PATH\feature\rdc200_fw_v1.6_gpioB_20171017.hex as FW
     • Select $RDC200_INIT_PATH\init_lut\rdc200\RDC200_for_RDP501H_20170904.rega as Controller-Init
     • Select $RDC200_INIT_PATH\feature\20170406_gamm2.0.lut as Controller-Gamma
     • Select $RDC200_INIT_PATH\init_lut\rdp550f\init_rdp550f-e_20170405.rega as Panel-Init
     • Select $RDC200_INIT_PATH\feature\bootlogo_00.bmp as Boot Logo
     • Check Generate LUT
     • And then click Start button.
     • 
   • Vista Studio™ will create rdcx000_lut_data.h in Default Download Folder  specified above .
5. Replace the rdcx000_lut_data.h located in $VISTA_CUBE_PATH/example/mcu_example/ with the rdcx00_lut_data.h made in the previous step.
   • e.g. Copy rdc200_lut_data.h made in step4 into $VISTA_CUBE_PATH/example/mcu_example/
6. Build and then execute your target system.
   • Don’t forget to include the downloading calling function. (Refer to main function in $VISTA_CUBE_PATH\example\mcu_example\main.c)
     • rtiVC_Initialize(RDC_I2C_SLAVE_ADDR);
     • rtiVC_OpenDevice();
     • (Optional) rtiVC_RegisterDownloadCallback(...);
     • rdc200_download();
     • rtiVC_CloseDevice();
     • rtiVC_Denitialize();
     • 
   • After finishing, reboot. Then you will see an input video if there is video source, otherwise you will see the bootlogo image on your panels.
