顶了。
安鑫的活动，支持一下。

每次下决心不再买垃圾了，可是每次活动，都觉得太值了。

哎，病入膏肓，没办法。

入手了这个手柄，主要是看中了里面的
WT6573F
USB Device Controller with 16KB Flash


1. Introduction
1.1 General Description
WT6573F is a USB full speed / low speed device controller with Turbo 8052 CPU, 16K-byte Flash ROM, 512-byte  SRAM,  19-channel  12-bit  ADC,  2-channel  8-bit  PWM,  standard  RS232  interface,  SPI master/slave  interface,  In-System-Programming  (ISP) function  by  USB  or  I2C  interface,  and  on-chip ICE.
WT6573F is suitable for the USB peripheral applications, such as: PS3 game pad/joystick, USB game controller, USB MIDI keyboard, USB touch-pad, or any USB devices with ADC applications. When  USB-related  circuit  and  V33  regulator  are  disabled,  WT6573F  could  be  used  for  portable applications which are powered by battery (VBAT <= 3.6V).
