  2. On Board Computer • Project assignment • OBC Interfaces • I2C hardware • I2C Software • Char WriteI2C(Destination, module, DataLength, *DataPointer) • Char ReadI2C( ) • Boolean BufferI2C( ) • ComBus Hardware • ComBus Software • Int StatusCom( ) • Boolean BufferCom( ) • Char ReadCom( ) • Char WriteCom(Data)

  3. On Board Computer • Bootsequence • PSU as an intelligent external boot master • Boot from PROM or EEPROM • Boot timeout • PSU as watchdog

  4. On Board Computer • Redundancy and robustness • I2C-Bus • CRC checksum • Header/Stop condition • OBC • Oscillator watchdog • Software watchdog • Hamming code • Boot Software Copy

  5. Payload • Devitech • Kodak kac-1310 • 1.3 million pixel • 10 bit colour • Lens: • Considerations

  6. The Next Step • Problems • Get a Pal unit which is OTP • Get a lens • What we will do now • Try to get the parts we need

  7. The End KISSASS Keep It Super Simple And So Stupid
