2.2 Front-Page Indicators and Functions

Figure 2-2 shows the main screen of the EVM software. The indicators and buttons located above the tabbed section of the front page are visible regardless of which tab is currently selected.

At the top left of the screen is an Interface indicator. This indicator shows which interface is selected for controlling the TLV320AIC310xEVM.

To the right of the Interface indicator is a group box called Firmware. This box indicates where the firmware being used is operating from—USB-MODEVM or AC-MODEVM. The GUI will auto detect which version of MODEVM is connected. In this example it is with the USB-MODEVM, so the user should see USB-MODEVM in the box labeled Located On:. The version of the firmware appears in the Version box below this box.

To the right, the next group box contains controls for resetting the TLV320AIC310x. A software reset can be done by writing to a register in the TLV320AIC310x, which is accomplished by pushing the button labeled Software Reset. The TLV320AIC310x also may be reset by toggling a pin on the TLV320AIC310x, which is done by pushing the Hardware Reset button.

CAUTION:

In order to perform a hardware reset, the RESET jumper must be installed and SW2-7 on the USB-MODEVM must be turned OFF. Failure to do either of these steps results in not generating a hardware reset or causing unstable operation of the EVM, which may require cycling power to the USB-MODEVM.

On the lower left portion of the screen, the Device Connected LED must be green when the EVM is connected. If the indicator is red, the EVM is not properly connected to the PC. Disconnect the EVM and verify that the drivers were correctly installed, then reconnect and try restarting the software.

On the upper right portion of the screen, several indicators are located that provide the status of various portions of the TLV320AIC310x. These indicators are activated by pressing the Indicator Updates button below the Firmware section. These indicators, as well as the other indicators on this panel, are updated only when the front panel of the software is inactive, once every 20 ms.

The ADC Overflow and DAC Overflow indicators light up when the overflow flags are set in the TLV320AIC310x. Below these indicators are the AGC Noise Threshold Exceeded indicators that show when the AGC noise threshold is exceeded. To the far right of the screen, the Short Circuit Detect indicators show when a short-circuit condition is detected, if this feature is enabled. Below the short-circuit indicators, the AGC Gain Applied indicators use a bar graph to show the amount of gain applied by the AGC, and indicators that light when the AGC is saturated.
