闻亭公司的测试程序，包括LED、EEPROM、DAC、PLL、boot等程序。-Wen Ting companies testing procedures, including LED, EEPROM, DAC, PLL, boot, and other procedures.

2407上的AD转换功能，很重要的数据采样环节。-This program initializes the ADC module of the 240x and does a conversion of all the analog input channels. The results of the conversion are available in the RESULTSn register, which can be accessed by the user application. The ADC operates as one 16-state sequencer & the conversions are stopped once the sequencer reaches EOS (End of sequence)

这是一款关于信号处理的芯片，由我们可以借鉴的地方，了解一下它的强大功能吧-This is a signal processing on the chip, we can learn from the lessons of, check it out powerful it

DSB-SC信号的生成与解调 1) 用离散（DSP）的方法生成DSB信号 2) 载波频率为150KHz，音频为500Hz和2000Hz的混合音。 3) 加入高斯白噪声 （4） 语音信号 的传输。 改变抽样频率和量化台阶大小，观察重建信号以及量化噪声信号的波形；对于语音信号主观评价声音质量的变化。 -DSB-SC signal generation and demodulation 1) Discrete (DSP) methods to generate DSB signal 2) the carrier frequency to 150KHz, audio 500Hz and 2000Hz for the mixed tone. 3) by adding white Gaussian noise (4) transmission of voice signals. Change the sampling frequency and quantization step size, to observe the reconstruction of signal and quantization noise signal waveform for subjective evaluation of the speech signal changes in sound quality.
