NT-NAU83G60

本指南将逐步说明如何使用 NAU83G60YG 搭配 KCS 算法,让扬声器快速运作。

Required Hardware, Software, and Files
G60 NAD Demo board Hardware
Power Supply (24V, 5A) Hardware
USB Mini Cable Hardware
Speaker Hardware
Computer with Windows 10 (or newer) Hardware

(*) 取得 KCS 初始参数

使用 KCS 控制扬声器时,需要一组 KCS 初始参数。此数据集用于描述扬声器模型的特性(即安装于音箱中的参考换能器)以及目标扩大器(本例中为 NAU83G60YG)。此数据集已储存于 KCS Monitor GUI 中,方便使用者存取。

 

KCS 初始参数可透过以下两种方式取得:

 

  1. 若扬声器为评估套件中的产品(参考扬声器),KCS 初始数据将随附于套件中。
  2. 若要在自有扬声器上使用 KCS,则需先进行量测以取得 KCS 初始数据集。此步骤需使用 Klippel 软件模块 KCS-ID Parameter Identification,并搭配 Klippel Analyzer 硬件(KA3)。详细流程请参阅 klippel.de/go/kcs-eval 。若您无法取得上述工具,该页面亦提供替代方案的操作指引。
# Function Description
D1 TBA (reserved for SD Card Slot)
D2 Heartbeat.
  • Flashing on and off in 1 second intervals = FW is running
  • Off = FW is not running
D3 FW Update Mode via ISP Tools indicator. When ON, FW update via ISP Tools is ready.
D4 GREEN KCS LED Indicator for NAU83G60 Right Channel
  • On = Device is present; KCS Algorithm is NOT activated
  • Off = Device is not present
  • Blinking = KCS Algorithm is ACTIVE
D5 RED KCS LED Indicator for NAU83G60 Left Channel
  • On = Device is present; KCS Algorithm is NOT activated
  • Off = Device is not present
  • Blinking = KCS Algorithm is ACTIVE
D6 TBA
D7 USB/I2S2 playback input
  • On = I2S2 playback input
  • Off = USB playback input
D8 I2S Disable LED Indicator. If ON, I2S0 from the M4 to G60 chip is in hi-Z. Customers will need external I2S to drive G60. Intended to help develop customers' FW and test I2S and I2C from their board.
