Help Needed: Ch7010 Tv output

Hi,

Sorry for the delayed response.

here are the ch7010 settings for VGA output. These settings are for the VGA resolution output 640x480 from the DVI port.

i2c_write(base_address, 0xea>>1, 0x15, 0x00 );

i2c_write(base_address, 0xea>>1, 0x31, 0x00 ); //

i2c_write(base_address, 0xea>>1, 0x32, 0x23 ); //

i2c_write(base_address, 0xea>>1, 0x33, 0x08 ); //

i2c_write(base_address, 0xea>>1, 0x34, 0x16 ); //

i2c_write(base_address, 0xea>>1, 0x35, 0x30 ); // chrontel

i2c_write(base_address, 0xea>>1, 0x36, 0x60 ); //

i2c_write(base_address, 0xea>>1, 0x37, 0x00 ); //

i2c_write(base_address, 0xea>>1, 0x49, 0xc0 ); // Set DVI MODE

i2c_write(base_address, 0xea>>1, 0x21, 0x01 | 0x08 ); // DAC bypass

i2c_write(base_address, 0xea>>1, 0x22, 0x16 ); // BCO = VSYNC

i2c_write(base_address, 0xea>>1, 0x1c, 0x04 ); // Invert XCLK Polarity

Hope this would help.
