Overview

Structs used by the driver.

Note

This is an example show how to instantiate CAM with cam_instance_t, cam_api_t.

#include "cam/cam.h"

#define I2C_CTRL_HZ SYSTEM_CLINT_HZ

#define I2C_CTRL (i2c_hwreg_t *)SYSTEM_I2C_0_IO_CTRL

#define I2C_FREQ 100000

CAM_instance_t CAM = {

.drv = &CAM_DRIVER,

.inst = &(i2c_instance_t){

.hwreg = I2C_CTRL,

.slaveAddress = CAM_CTRL,

.samplingClockDivider = 3,

.timeout = I2C_CTRL_HZ/1000,

.tsuDat = I2C_CTRL_HZ/(I2C_FREQ*5),

.tLow = I2C_CTRL_HZ/(I2C_FREQ*2),

.tHigh = I2C_CTRL_HZ/(I2C_FREQ*2),

.tBuf = I2C_CTRL_HZ/(I2C_FREQ),

},

};
