It is OK for machine vision and small applications.ĭue to the speed limitation of AVR series MCU, and all the Read and Write access to LCD GRAM is emulated by IO operation, saving a 320×240 RGB555 BMP into SD/TF card will take up 10 seconds and transmit the image over bluetooth needs 15 seconds. We can’t live without the LCD screen because we use the LCD GRAM as a frame buffer. The image resolution is limited by the LCD screen, so it only supports QVGA(320×240) preview resolution or equivalent 150KB size (around SXGA 1280×1024) JPEG image. Limitations ( The limitation is improved in the ArduCAM Rev.B and Rev.C) Once the capture button is pressed, the state machine will freeze the screen and enter capture mode, the MCU will read the image data from LCD’s GDDRAM and save to SD/TF card. When start the state machine will enter preview mode, the Chip DMA the camera data to LCD screen directly with frame rate upto 30fps. ArduCAM library provide simple interface for sensor initialization, triggering a capture and read image data to external SD/TF card.ĪrduCAM incorporate with a ArduChip, which used to do the DMA transfer between camera module and LCD internal GDDRAM, control the camera data stream timing and do the GPIO expansion. Two libraries are written for ArduCAM shield, one is UTFT library which is used for accessing the LCD screen, the other is ArduCAM library which supports different kind of camera modules registers configuration via I2C and accessing ArduChip internal control registers. ![]() We will add support (already supported sensors are marked in red) to various of camera module which use Omnivision and Aptina CMOS image sensor, something like It is good to know that Henning Karlsen has already develop a open source library named UTFT for Arudino, it also support this LCD controller. It interfaces to Arduino with 8bit 8080 type bus interface. The TFT LCD is 3.2 inch QVGA ( 320×240 ) LCD, it use SSD1289 LCD controller and consists of up to 172,800 bytes (240 x 320 x 18 / 8) Graphic Display Data RAM (GDDRAM).
