THIS PRODUCT HAS BEEN RETIRED FROM CATALOG AND IS NO LONGER FOR SALE. THIS PAGE IS MADE AVAILABLE FOR THOSE LOOKING FOR DATASHEETS AND THE SIMPLY CURIOUS.

SparkFun Part Number: WIG-09306

Description: The O-Clock can convert your X-Y analog oscilloscope into an analog clock or terminal. In addition, it can be used alone as a function generator. It is very similar to the AVR Oscilloscope Clock Kit, but this board is all SMD and comes fully assembled.

The O-Clock is based around an ATmega328 which is interfaced with a DS1307 RTC module and an AD7302 DAC. A cell battery backup is provided so the clock won't lose its time. The oscilloscope can be connected to the O-Clock through BNC connectors (not included) or by probing the CH1/2 turrets.

Time and other options can be set using the on-board momentary push buttons, or through the RS-232 interface. A 0.1" pitch header provides access to the UART of the ATmega to allow for an optional USB interface using our FTDI Basic Breakout. GPS modules or other external PPS signals can be connected to serve as an external clock.

The pre-programmed firmware is loaded with features. There are 37 display combinations to choose from. You can even use the O-Clock in terminal, or function generator modes. In addition, a bootloader allows for easy firmware uploading.

The terminal application can support persistent vector graphics for creating and displaying games, like Asteroids, on other computers.

Power can be provided by USB or an 8-15VDC supply to the center-positive 5.5x2.1mm barrel connector.

Note: Power supply and BNC connectors are not included, see related related items.
