Troubleshooting Information

Power LED does not illuminate

In case the power LED does not illuminate it is likely that the board is not powered.

Possible Solutions:

• Check the board is connected to your PC’s USB port.

• Change the USB cable or use a different USB port on your PC.

• Check if the PC is switched on.

LED 1 blinks fast

When LED 1 blinks fast (~10 Hz) the USB connection is not established towards the PC.

Possible Solutions:

• Make sure the Windows CDC driver is installed (refer to Appendix D. “Driver Installation Man-

ual”).

• Makes sure the MGC3130 Unit and the I2C™ to USB Bridge are already connected before plugging

in the USB connection (refer to Section 2.2 “Step 1: Build-up Development Kit”).

• Reconnect the board by unplugging and plugging in again the USB connection.

Signal streaming stops

Signal stream in Aurea GUI stops when there is no approach towards the sensing area. This behavior is

intended. When using the Aurea GUI, the Wake-up on Approach feature is automatically enabled.

Possible Solutions:

Disable the Wake-up on Approach feature in the Real-Time Control bar of Aurea by unchecking the

Approach Detection/Power Saving check box for continuous signal streaming.

No Position data displayed, Electrode signals are zero

Signal matching parameters have been mismatched and accidentally stored into the Flash.

Possible Solutions:

• Perform “Autoparameterization” in the AFE Parameterization of Aurea Setup tab. Make sure there is

no hand approach towards the electrodes during autoparamterization process.

• Restore the default Signal Matching parameters by re-flashing the original MGC3130 GestIC®

Library file.

LED 1 and 2 on I2C™ to USB Bridge are off

When LED 1 and LED 2 on the I2C™ to USB Bridge are off but the power LED is on, the PIC18F14K50

is in Bootloader Update mode and therefore not operating code. The PIC18F14K50 will start in Bootloader

Update mode in case the MGC3130 Unit is not connected to the I2C™ to USB Bridge.

Possible Solutions:

• Please disconnect the I2C™ to USB Bridge from USB. Connect the MGC3130 Unit and the I2C™ to

USB Bridge first and then plug in the USB connection.
