MSP430下的一个微内核操作系统，很实用。做到底层无关，稍加修改可以移植到其他平台下。-MSP430 under a micro-kernel operating system, is very practical. Do not bottom, a little change can be transferred to other platforms.

this directory contains the following: * The acdc algorithm for finding the approximate general (non-orthogonal) joint diagonalizer (in the direct Least Squares sense) of a set of Hermitian matrices. [acdc.m] * The acdc algorithm for finding the same for a set of Symmetric matrices. [acdc_sym.m](note that for real-valued matrices the Hermitian and Symmetric cases are similar however, in such cases the Hermitian version [acdc.m], rather than the Symmetric version[acdc_sym] is preferable. * A function that finds an initial guess for acdc by applying hard-whitening followed by Cardoso s orthogonal joint diagonalizer. Note that acdc may also be called without an initial guess, in which case the initial guess is set by default to the identity matrix. The m-file includes the joint_diag function (by Cardoso) for performing the orthogonal part. [init4acdc.m]

HT1621 是一款128 个位元的LCD 控制器件，内部RAM 直接对应LCD 的显示单元。相应的软件使它适用于包括LCD 模块和显示子系统在内的多功能应用。主控制器与HT1621接口只需4 到5 根线。内置的省电模式极大的降低了功耗。本文介绍HT48R05A-1 单片机来控制HT1621，并介绍如何turn ON 及turn OFF LCD 所有位元。-HT1621 is a 128-bit LCD control device, the internal RAM directly correspond to the LCD display unit. So that it applies to the appropriate software, including LCD modules and display sub-systems, including multi-purpose applications. Master controller and the HT1621 interface only 4-5 lines. Built-in power-saving mode greatly reduce power consumption. This article describes the HT48R05A-1 microcomputer to control the HT1621, and describes how to turn ON and turn OFF LCD all the bits.
