Camera Driver

Overview

Camera driver.

This module provides Generic functions to configure and control CAM input/output and interrupt behavior.

Usage & Initialization.

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

This implementation depends on I2C Driver.

#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),
},
};
