老外写的基于arm的sd/mmc读写程序，开源的项目

用C实现信号发生装置：1、正弦波：频率、幅度可调。 2、三角波：频率、幅度可调。 3、方 波：频率、幅度、占空比可调。 4、按键：波形切换、频率调节、幅度调节、方波占空比调节。 5、显示：信号的频率、幅度，在方波时还要显示占空比。 -Implementation using C Signal: 1, sine wave: frequency, amplitude adjustable. 2, triangle-wave: frequency, amplitude adjustable. 3, square wave: the frequency, amplitude, duty cycle adjustable. 4, button: switch waveform, frequency regulation, rate regulation, adjust the duty cycle square wave. 5, show that: the signal frequency, amplitude, when they showed at the duty cycle square wave.

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。-HT1621 is a 128-bit LCD control devices, directly correspond to the internal RAM of the LCD display unit. The corresponding software to make it applicable to including LCD modules and display subsystems, including multi-purpose applications. Host controller interface with HT1621 only 4-5 lines. Built-in power-saving mode greatly reduces power consumption.
