his document is an update Treflecting the changes made to Jeff Koenig's Infrared detector circuit. The assembly code and circuit are unchanged but the printed circuit artwork and documentation have been upgraded to make assembly easier. 有图。

用AU9610 控制鼠标的手册（E文） The AU9610 is an integrated USB mouse controller chip. It supports traditional ball mouse using low cost photo sensor as well as modern optical mouse using Agilent optical sensor. It can support up to 5 definable buttons that could be configured as the basic !°Left!±, !°Right!± !°Middle!± button and any other !°hot!± buttons, such as Internet, e-mail, previous page, n page!-etc. To simplify prototype development and production phase in, the AU9610 has 4 built-in USB descriptors allows a single chip to be deployed in 4 different models. In addition to the internal ROM, all USB descriptors and mouse configurations can be customized using an external EEPROM. This feature enables instant prototyping by just filling out a 256-byte table. To cope with the variation of photo diode and photo transistor in analog ball tape mouse, the AU9610 is designed with a patent pending adaptive control circuit. This feature dramatically reduces the overhead of sorting photo diode and transistor pair in the production line, hence reduces inventory, labor cost and improves production yield.
