3. f the cable is connected to the AVR Prog S and the female end to the host computer 2 Connecting to the MCU board Depending on the target device you will need to connect it via the 6 pin or 10 pin header If the device uses standard pin out See page 4 a simple ribbon cable with IDC connectors can be used Alternatively DuPont style jumpers can be used to bring the individual signals to the target device If jumpers are used be sure that the ground GND of the AVR Prog S is connected properly to the ground of the target device Failure to do this will almost certainly mean things won t work MOSI MISO and SCK are also required for normal programming operation Optionally The AVR Prog S can be used to power the target device This should only be done if the power requirements of the target device are minimal Read on for more information about this 3 Attaching the power optional The AVR Prog S itself gets its power from the RS232 interface and does not require and external power However some target devices may require the programmer to supply power In these cases the on board regulator and standard DC power jack allow for a variety of power e options Any filtered DC source of Positive between 7 5V and 23V can be used Negative Q Omega MCU Systems Page 3 Copyright 2012 Make sure the chosen power supply delivers positive voltage through the center conductor and negative through the outer sleeve as

5. shown above The most convenient and popular power sources are a 9V AC DC switching type switchmode adapter or a 6 cell AA battery pack The 9V AC DC switching type switchmode adapters are preferred over the transformer type adapters and batteries as they provide a more stable supply are lighter take up less space and are generally less expensive to use With a Vin of 9V the AVR Prog S power supply is capable of supplying about 100 mA If the target device requires more current than that you will need to provide sufficient power from another source At this point you are ready to begin downloading programs to your MCU Power selection Should it be necessary to use the AVR Prog S to power KoV EA the target device you will need to set the power GRN properly There are two jumpers provided for power selection The VS jumper determines the voltage supplied by the AVR Prog S 5V is supplied with the jumper installed and 3V with the jumper removed The red LED will light to indicate when 3V is available With the PS jumper installed the on board supply is attached to the Vcc pins on the ISP headers Remove this jumper if the AVR Prog S is not going to power the target device Q Omega MCU Systems Page 4 Copyright 2012 In Circuit Serial Programming In System Programming ICSP ISP rd ICSP or ISP In System programming is a method by which an MCU can be directly programmed while still in a circuit In I the AVR
