Hardware Agnostic Driver for using the OV2640 based ArduCam. This library is currently friendly to low level embedded platforms. This is currently not as full featured as the original ArduCam arduino library supports many camera platforms as well as has other image format. Currently the only support image format for this platform is JPEG. Other functionality should be easy to add. This code was adpated from their ESP32 example.

Currently, all of the available libraries for this camera are all platform specific (arduino, ESP32, raspberry pi) so there would be a significant amount of dev effort involved to port over to another platform. With this repo, I've partially made it usable on any system via funtion pointers so that the end user only needs to provide hardware specific functions in order to get it working on their MCU.

My code was adapated from the below repo https://github.com/ArduCAM/ArduCAM_ESP8266_UNO

• TI CC3235 ( Wifi SoC)

Below shows the init sequence and functions you would need to provide to use the library. I recommend reviewing some of the original ArduCam code to get a grasp of what's happening. Please check the full example as reading data from the camera is currently highly entangled with your actual application. In the original case, thsi was set up for camera streaming so partial blocks of the image were sent over the network. I have not yet produced an example in which a full image is read before processing.

void main(void *arg0)
{

    ArduCam_t acam;
    acam.spi_write = acam_spi_write;
    acam.spi_read = acam_spi_read;
    acam.spi_cs_low = acam_spi_cs_low;
    acam.spi_cs_high = acam_spi_cs_high;
    acam.i2c_write = i2c_write;
    acam.i2c_read = i2c_read;
    acam.delay_ms = acam_delay_ms;

    ACAM_Init(&acam);
    ACAM_OV2640_set_JPEG_size(&acam,OV2640_320x240);

    ACAM_clear_fifo_flag(&acam);

    while(1){
        ACAM_clear_fifo_flag(&acam);
        ACAM_start_capture(&acam);

        /* wait for a capture to finish */
        while(!ACAM_get_bit(&acam,ARDUCHIP_TRIG, CAP_DONE_MASK));
        camCapture(&acam);
        Task_sleep(1);
    }

}
