µCAM – II Serial Camera Module 4D SYSTEMS µCAM-II 1. Description 2. Features The uCAM-II (microCAM-II) is a highly integrated serial camera module which can be attached to any host system that requires a video camera or a JPEG compressed still camera for embedded imaging applications. The module uses a CMOS VGA colour sensor along with a JPEG compression chip that provides a low cost and low powered camera system.

µCAM – II Serial Camera Module 4D SYSTEMS µCAM-II 4. Pin Descriptions 5. Serial Interface - UART 5V pin 1 (uCAM-II Supply Voltage Input): Module supply voltage input pin. This pin must be connected to a regulated supply voltage. 4.5V to 9.0V DC range, nominal 5.0V. The uCAM-II has a dedicated hardware UART that can communicate with a host via this serial port. This is the main interface used by the host to communicate with the module to send commands and receive back data.

SNAPSHOT (AA05h) The uCAM-II will hold a single frame of still picture data in its buffer after receiving this command. This snapshot can then be retrieved from the buffer multiple times if required. 6.3.1. Snapshot Type Compressed Picture (JPEG) Uncompressed Picture (RAW) 00h 01h 6.3.2.

µCAM – II Serial Camera Module 4D SYSTEMS µCAM-II 6.9. ACK (AA0Eh) This command indicates the success of the last operation. After receiving any valid command, the ACK command must be sent out except when getting data. The host can issue this command to request image data package with the desired package ID after receiving the DATA command from the uCAM-II. The host should send this command with package ID F0F0h after receiving a package to end the package transfer.

µCAM – II Serial Camera Module 4D SYSTEMS µCAM-II 7. Command Protocol This section outlines command usage and protocol transaction between the host and the uCAM-II module. ACK and NAK responses are typical as replies from the Camera after sending a command, however silence is also possible if the camera has gone to sleep. Please refer to Section 6.9 and 6.10 for ACK/NAK information. 7.1.

4D SYSTEMS µCAM-II 7.2. INITIAL, GET PICTURE, SNAPSHOT, SET PACKAGE SIZE, RESET Commands When an INITIAL, GET PICTURE, SNAPSHOT, SET PACKAGE SIZE, or RESET command is sent to the camera, the camera will simply reply with an ACK if successful. Please refer to Section 6.9 and 6.10 for ACK/NAK information. 7.2.1.

Troubleshooting Q) Cannot connect to the camera, SYNC always fails A) Unplug the camera and plug it in again, try to SYNC again. If this fails, then the power supply you are using may have a slow rise time. Testing of power supplies with a rise time of under 5uS resulted in correct operation. Power supplies with a rise time of greater than about 50uS resulted in trouble to SYNC. Change your power supply and try again.
