CCs 0 99 计数器显示应用程序

本程序是MP3的解码程序，可以用VC编译或者用GNU编译，可以运行在PC机上。 本程可以MP3文件解压为WAV文件 TEST 中的代码可以播放WAV文件 有兴趣的朋友可以把这段mp3程序移植到开发板上，这样就可以用开发板播放MP3了-MP3 decoding procedures that can be used with VC or GNU compiler compiler. can run on the PC. The process can decompress MP3 to WAV TEST document of the code can be broadcast WAV documents are interested friends this can be transplanted to mp3 development board, we can develop with the board to broadcast MP3

总账系统是一个基本的系统，以处理凭证为核心，相应进行账簿报表的查询。各业务系统生成的凭证与总账无缝联接，即以各业务系统明细数据为基础，按发生的经济内容在总帐系统直接生产凭证，日常财务信息可直接在总账中进行查询-General ledger system is a basic system to deal with a certificate at the core, the corresponding query statements to the books. The operational system-generated certificate with the general ledger seamless connectivity, that is, details of the operational system data, according to the economic content of direct production in the general ledger system certificates, day-to-day financial information can be directly carried out inquiries in the general ledger

低频数字式相位测量仪； 此系统由相位测量仪、数字式移相信号发生器和移相网络三部分组成。为使系统更加稳定，使系统整体精度得以保障，本电路两块T89C52为核心控制器件分别控制相位测量、数字式移相信号发生,在数字式移相信号发生部分采用了锁相技术、CPLD等技术, 使输出波形精度大大提高，并可对频率自动校验，提高频率稳定性。-low-frequency digital phase-measuring instrument; This system consists of phase-measuring instrument, digital phase shifting generator and phase three network components. To make the system more stable, the overall accuracy of the system can be protected, the two T89C52 circuit control devices at the core respectively phase measurement control, digital believe the shift occurred, the digital shift occurred some believe that the use of lock-in technologies, such as CPLD technology, the output waveform accuracy greatly improved, and can automatic calibration frequency, frequency stability.
