Section 2
Preparing the
ATmegaICE System for Use
Complete the following procedure in order to start using the ATmegaICE.
Before connecting the probe cable to the user application:
1. Connect the pod card to the AVR ICE unit with the pod cables. Do not disassem-
ble the pod cables.
2. Connect the probe cables to the pod. See Section 4 for details.
3. Connect the RS-232 cable between the AVR ICE unit and an available serial port
on the host PC.
4. Connect a power supply (9 - 15 VDC, negative center) to the ATmegaICE unit.
The power supply delivered with your ATmegaICE is correctly dimensioned.
5. Turn the power on and check that the red LED marked “POWER” is lit.
6. After a short time (<10 s) the green LED marked “READY” will be lit and the
ATmegaICE system is ready.
7. Turn the power off.
8. Solder the TQFP64 adapter PCB part of the probe connector to the target PCB.
9. Connect the probe into the application, and pay attention to connect it correctly. If
it is not connected correctly, your ATmegaICE system may be damaged.
10. When the probe is correctly connected to the application, check the jumper
marked “J500” (Ext.Power) on the ATmegaPOD (see Figure 3-1). If the applica-
tion is to be powered from the ATmegaICE unit, the jumper should be mounted. If
the application is to use its own power supply, the jumper must be removed.
11. Make sure that the voltage regulation, external clock and Timer oscillator are set
according to the target system requirements (see Section 3).
12. When all jumpers are set, turn the power on. When the green LED is lit, the AVR
ATmegaICE system is ready for use. Start AVR Studio, and begin your AVR emu-
lation session.
It is possible to use the ATmegaICE without the ATmega probe and the TQFP64
adapter if four 8 x 2 pin headers are added to the target application PCB.
Tables 4-1, 4-2, 4-3 and 4-4 give details on how to use these header connectors. Con-
nect the pin headers on the target application to the In-System connectors on ATmega-
POD by using the probe cable included in your kit.
