CONNECT THE DEVELOPMENT SYSTEM
To connect the development system, take the following steps:
1.
Ensuring correct orientation, insert an ADuCM330/
ADuCM331
device. Note that Pin 1 of the device is
indicated by a dot in the corner. The dot on the device
must be orientated with the dot on the socket, as shown
in Figure 1.
Figure 3. ADuCM331 Device Orientation
2.
Connect the debugger/programmer, noting the correct
orientation as shown in Figure 4.
3.
Connect a 12 V supply between VBAT and GND.
4.
Ensure that the board jumpers are in position, as shown in
Figure 1.
JUMPER FUNCTIONALITY
Table 1.
Jumper
Functionality
J4, GPIO0, GPIO1
These jumpers connect the push buttons to GPIO0 and GPIO1 of the device.
J4, GPIO2, GPIO3
These jumpers connect the two LEDs to GPIO2 and GPIO3 of the device.
J4, GPIO4, GPIO5
No functionality.
GPIO5 (beside LIN)
This jumper ties the GPIO5 pin of the device to GND. This jumper must be connected when programming the
device or when accessing via serial wire debug (SWD).
3V3_REG
This jumper enables the 3.3 V regulator on the underside of the PCB. It is used to power the LEDs or an additional
3.3 V source.
LIN
This jumper disconnects the LIN terminal (green banana socket) from the device.
IDD, IDD1
These jumpers allow the insertion of an ammeter in series with the VBAT supply through the I
current measurement.
VIN_AUX, IIN_AUX
These jumpers allow a direct connection to ground of the INNx_AUX and VINx_AUX pins.
IGND
This jumper connects the INN− pin of the IADC to GND.
IIN
This jumper shorts the inputs of the IADC.
NTC
This jumper allows an external temperature device to be connected between VTEMP and GND_SW of the device.
J2
J2 is the SWD programming interface. Check orientation with Figure 4.
J3
J3 allows a connection for LIN to operate in UART mode.
J4
J4 is a GPIO header.
J11
Ground header.
EVAL-ADUCM331QSPZ User Guide
5.
Ensure that the GPIO5 jumper is in place (beside the LIN
jumper). The GPIO5 jumper is used by the on-board
kernel to determine program flow after a reset. See the
Kernel section in the
Reference Manual
6.
Press RESET.
