高频头1256编程，可LCD显示频道好，此原码为8个频道解调，其他频道请类推！-Tuner 1256 programming, LCD display can be a good channel, the original code for the 8-channel demodulation, and so on other channels, please!

老外做的软件实现DTMF-foreigner Software DTMF

SD卡驱动 SD_CARD_TIMEOUT 当一个SD卡的操作超出时限，将导致返回错误和该标记被置位 SD_CARD_EXIST 当卡槽内插入了合适的卡体，不管是什么卡，都会使该位被设置； SD_CARD_WRITE_PROTECT 当卡体的写保护开关被 LOCK 时，则该位被设置； SD_CARD_READY 当卡槽内的卡被正确识别，并可以随时访问时，则该位被设置； SD_CARD_DOOR_CLOSE 当卡槽的门（产品外壳上的挡板开关）关闭时，则该位被设置； SD_CARD_IS_SD 当卡槽内插入的是 SD 卡时，则该位被设置。 SD_CARD_IS_MMC 当卡槽内插入的是 MMC 卡时，则该位被设置； 注意：不要使用 0x80，免得和整数作逻辑运算时被误为负数。-err

通过ＭＣＵ采集数据并上传到ＰＣ，通过串口协议传送-Through the MCU data collection and upload to the PC, through serial transmission agreement

这个源代码是关于MCS-51的无线接收，用89S52控制MT8870B进行DTMF解码。程序相当的经典，本人调试了几周后，达到了非常好的效果。误码率相当的小。我觉得好东西要大家分享的，所以今天我上传此代码，与大家共同分析进步。-the source code is on the MCS-51 wireless receiver, S52 control with 89 MT8870B for DTMF decoder. Quite the classic procedure, I debug a few weeks later, to achieve very good results. The error rate is very small. I think that good things should be shared, so I upload this code, and the analysis of common progress.
