Reason
STK512 Interface Board not correctly connected to
STK500
ISP ribbon cable not connected properly
Incorrect device selected
Device present in STK500 sockets
ISP jumper not shorted on STK512 Interface Board
Power and serial cable not connected to STK500
Battery dead
Demo Software corrupted
Switch contact not made
Low Battery voltage
Transmitter is in sleep mode
Demo Software corrupted
Demo Software corrupted
Incorrect orientation of the ribbon cable connecting the
ISP header to the STK500
Power not supplied to transmitter on-board
microcontroller
Wrong device selected in the STK500 software
Power and serial cable not connected to STK500
Incorrect orientations of the Receiver Application Board
or STK512 Interface Board
Power not properly supplied to all boards
Data Selector switch not set to STK500 position
Microcontroller socket on STK500 not populated
Corrupted software in the STK500 microcontroller
10-pin ribbon cable not connected properly
Incompatible modulation used on the transmitter and
receiver
Receiver set to permanent sleep
Receiver limits incorrect
Receiver antenna not connected
Solution
Verify EXPANDO and EXPAND1 are properly oriented
Ensure ribbon cable connected between ISP6PIN header
and SPROG3 header
Check orientation of pin 1 on headers
Select ATmega8515 from the Device menu. Verify that the
signature byte matches in the Advanced tab
Remove all devices from the programming sockets of the
STK500
Connect shunt
Verify setup of the STK500 hardware
Open Transmitter Application Board case and replace
coin cell battery
Reload the desired software according to Section 2.2.
Ensure proper contact of the button to the Transmitter
Application Board
Replace coin cell battery
Press button to wake from sleep mode
Reload the desired software according to Section 2.2.
Reload the desired software according to Section 2.2.
Verify the orientation of both sides of the ribbon cable
Supply 3 volts to the transmitter microcontroller through
the coin cell battery or via the STK500
Select ATtinyl3 from the Device menu. Verify that the
signature We matches in the Advanced tab
Verify setup of the STK500 hardware
Verify the hardware is assembled correctly as shown in
Section 2.
See the troubleshooting section for each board.
The demo uses an ATmega88 microcontroller in the
STK500 to decode the received signal
Reload the Receiver Decode software as shown
in Section 2.
Verify that the 10-pin ribbon cable is properly connected
to the LEDS header from the PORTC header on the
STK500
Verify that transmitter and receiver are both set for the
same modulation type (ASK versus FSK)
Check for Sleep bits in the OPMODE register set for all 1s
Verify correct register settings as given in Section 2.
Connect external whip antenna to Receiver Application
Board
Set the switch to the proper position and re-run the demo
