ADV7513 video output issues.
what am I trying to do?
Want to convert RGB 24 bit (External DE,Vsync and Hsync) to HDMI.
I am sending a 800 x 480 video through RGB input of ADV 7513.
Below are the i2c settings.
HDMI_Write(0x41,0x10); // Power Up Transmitter
//Setup Video Input Mode
HDMI_Write(0x15,0xF0); //Video Format ID (24 bit RGB 4:4:4 or YCbCr 4:4:4 Separate Syncs) and I2S frequency Invalid
HDMI_Write(0x16,0x30); //Input Color depth (8 bit)
HDMI_Write(0x17,0x00); //Aspect ratio of input Video (Set for 4:3 but ours is 3:2)
//Setup Video Output Mode
HDMI_Write(0x18,0x46); //CSC Disable
HDMI_Write(0xAF,0x06); //HDMI Mode Select
After configuring this.i tried reading video mode detection registers
Auxillary VIC detected ----->101 ----->240P Active
Progressive mode information--------->case 1:240 P and 263 lines
VIC to Rx---------->VIC#8 240p-60 2 X clk 4:3
According to video mode detection description.
I tried setting manual and VIC manual to different setings....iam not able to see any data in HDMI.Please support for bring up.
thanks in advance.
