FX2N -32MT schematic

old gpio interface to other kernel modules don t use in new code, will go away in 2.7 have a look at bttv-gpio.c instead.

基本调节功能的电子钟 断电记忆 只为测试24C02(Basic regulatory function of the electronic clock off memory only for the test 24C02)

RX8025T 时钟芯片，高精度，精度每天0.5秒 时间通过串口发送(RX8025T clock chip, high precision, accuracy of 0.5 seconds every time sent through the serial port)

As the figure above illustrates, a phase accumulator compares the sample clock and desired frequency to increment a phase register. Again, the fundamental idea is that we can generate signals with precise frequencies by generating an appropriate sample based on the phase of that frequency at any point in time. In addition, by representing our waveform with 214 (16,384) points, we are able to represent exactly 16,384 phase increments with our lookup table.
