完成存储芯片SST25VF016B-D的读写操作。代码是使用C语言实现的，调用的函数是STM32F103VE芯片的封装函数，是STM32F103VE芯片连接flash的调试代码。

51系列单片机的数码管试验的C语言程序。-51 Series single-chip digital test tube C language program.

基本成功。 收到数据时，能点亮一个led。 单片机 STC12C5260S2   1T 延时用的是单片机小精灵 stc1T 模式编写 2011.1.8上午，发送程序已做部分优化，优化了延时，使延时更加短。 2011.1.8下午，接收程序已做部分优化，优化了延时，使延时更加短。 2011.1.9晚上定稿。此程序全部用查询法，此后将进行优化，用中断进行处理。 ///////////////////////////////////////// /////////////////////////////////////////

应用背景The CMX990 provides, on-chip: a flexible, formattable GMSK packet and freeformat modem, a dual synthesiser fed from an external source, IF and RF transceiver stages for both Rx and Tx modes, and auxiliary ADCs and DACs for system control and monitoring.关键技术Operating in the range of 400MHz to 1GHz at data rates of 4 to 16 kbps. This single-chip, half-duplex device requires a minimum of external components, keeping end-product board size, power consumption and cost to an absolute minimum. The versatile GMSK modem is configured for either packet and freeformat data operation via an efficient task-oriented Rx and Tx format and command structure combined with data scrambling, interleaving and FEC and CRC capabilities. Rx data acquisition, extraction and tracking functions use Rx data-quality feedback to support varying signal environments. IF and RF functions in the Tx path handle all the signal processing requi
