Firmware Setting
Generally, floating address method is used in firmware;
the configurations can changed in the “ncv7685.h” file. Here
are options:
1. Floating Address method using SOC GPIO:
#define NCV7675_CHIPS_NUM 0x04 /* Chips number */
#define PCA9655_Address 0x22 /* PCA9655 I2C address */
#define BY_SOC 0 /* SOC or PCA9655 */
#define
BY_PCA9655 1
#define ADDRESS_SETTING BY_SOC
#define Fix_Address 0
#define Address_Had_Set 0
2. Floating Address method using PCA9655:
#define NCV7675_CHIPS_NUM 0x04 /* Chips number */
#define PCA9655_Address 0x22 /* PCA9655 I2C address */
#define BY_SOC 0 /* SOC or PCA9655 */
#define
BY_PCA9655 1
#define ADDRESS_SETTING BY_PCA9655
#define Fix_Address 0
#define Address_Had_Set 0
3. Fix Address method using PCA9655 or SOC GPIO:
#define NCV7675_CHIPS_NUM 0x04 /* Chips number */
#define
PCA9655_Address 0x22 /* PCA9655 I2C address */
#define BY_SOC 0
#define BY_PCA9655 1
#define ADDRESS_SETTING BY_PCA9655 /* SOC or PCA9655 */
#define Fix_Address 1
#define
Address_Had_Set 0
4. For the board which address had programmed, just set “Address_Had_Set” to 1, So it will skip address setting
function:
#define NCV7675_CHIPS_NUM 0x04 /* Chips number */
#define
PCA9655_Address 0x22 /* PCA9655 I2C address */
#define BY_SOC 0
#define BY_PCA9655 1
#define ADDRESS_SETTING BY_PCA9655 /* SOC or PCA9655 */
#define Fix_Address 1
#define
Address_Had_Set 1
