i2c slave address conflict between B-LCDAD-HDMI1 and B-CAMS-OMV.

[WLeun.2]

When using both B-LCDAD-HDMI1 and B-CAMS-OMV together on STM32M747I-Disc, HDMI has no output. Finally, found that i2c address of OV5640 use the same address of ADV7533 CEC-DSI. Any solution?

Hello WLeun.2,

Sorry only detected your message recently. In case you would like to change the I2C address on ADV7533, you can handle the R5 resistor and put a 2 kohm recommended pull-down on PD pin. This would have effect to change the I2C address, but would also change the polarity of Power-Down PD pin : both I2C address and PD polarity are determined at ADV7533 power-up (when the supplies are applied to ADV7533). Explanation: The PD pin has an integrated pull-up for '1' polarity by default, and external pull-down can bring a forced '0' polarity at power-up. (Take care about any resistor present on pin 57 CN1 of Host side).

Hope this answers to your need. Best Regards,
