hi, i'm luis.

 

i have some question prim mode and vid std of adv7611.

 

First. how different pr 1x1 525p and pr 2x1 525p ?

 

Second, at component video mode , vid std value 0x1e & 1f are same?

 

Finally, do you have hdmi auto detect parameter of adv7611?

for example,  for my application, adv7611 check below parameters every few second when hdmi cable plugged.

but i dont have test equipment that various resolution output. so i request resolution parameters if you have.

 

//read Video input parameter

154         hdmi_resol_parameter[0] = ADV7611_I2C_Read16(HDMI_MAP_ADDR, 0x1E, 0x3fff );     //total_line_width

155         hdmi_resol_parameter[1] = ADV7611_I2C_Read16(HDMI_MAP_ADDR, 0x07, 0x1fff );     //line_width

156         hdmi_resol_parameter[2] = ADV7611_I2C_Read16(HDMI_MAP_ADDR, 0x20, 0x1fff );     //hsync_front_porch

157         hdmi_resol_parameter[3] = ADV7611_I2C_Read16(HDMI_MAP_ADDR, 0x22, 0x1fff );     //hsync_pulse_width

158         hdmi_resol_parameter[4] = ADV7611_I2C_Read16(HDMI_MAP_ADDR, 0x24, 0x1fff );     //hsync_back_porch

159         hdmi_resol_parameter[5] = ADV7611_I2C_Read16(HDMI_MAP_ADDR, 0x05, 0x30 );       //dvi_hsync_polarity & dvi_hsync_polarity

160         hdmi_resol_parameter[5] = (hdmi_resol_parameter[5]>>5) & 0x3;

161         hdmi_resol_parameter[6] = ADV7611_I2C_Read16(HDMI_MAP_ADDR, 0x26, 0x3fff );     //field_total_height

162         hdmi_resol_parameter[7] = ADV7611_I2C_Read16(HDMI_MAP_ADDR, 0x09, 0x1fff );     //field_height

163         hdmi_resol_parameter[8] = ADV7611_I2C_Read16(HDMI_MAP_ADDR, 0x2a, 0x3fff );     //field_front_porch

164         hdmi_resol_parameter[9] = ADV7611_I2C_Read16(HDMI_MAP_ADDR, 0x2e, 0x3fff );     //field_pulse_width

165         hdmi_resol_parameter[10] = ADV7611_I2C_Read16(HDMI_MAP_ADDR, 0x32, 0x3fff );    //filed_back_porch
