本程序是显示模块的例程，所接器件为四位八段led数码管，其中PTB0-PTB3 与数码管的位选相连接，PTB4，PTB5与74LS164连接确定你开发板上拨码开 关JP1（图片上的12）的两位和JP4（图片上的9）的5、6、7、8位处于on）， 而其他位处于远离on！-This procedure is the routine display module, the access device for four eight led digital tube, which PTB0-PTB3 bit digital tube and connected to the election, PTB4, PTB5 with 74LS164 sure you connect the development of on-board DIP switch JP1 ( picture on the 12) two and JP4 (picture on the 9) of 5,6,7,8 located at on), while the other located at far away from the on!

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

一个利用中断修改后进行的A/D采集功能的使用软件.-An interruption of the revised use of the A/D collection features the use of software.

这用来控制 ADI 设备 AD7988 与 NIOS II。AD7988 是一个高速模拟到数字转换器，它有 500 K/s 简单率和 16 位。它使用 3 针 SPI 到变送器的数据。首先这段代码从 AD7988，接收数据，然后将数据发送到一个 FIFO。FIFO 有 512 点深度和 16 位宽度。它将 trasmitter INT 到 NIOS，当它有 256 点数据。然后 nios 应该从 FIFO 中读取数据。

资源描述在这个项目中，你会得到一些校长对于VHDL逻辑信息添加三位。 ；你知道当我们添加三位输入，我们将给予两位的输出。一、乙和丙是输入和D、c_out输出。有关全加器的更多信息，您可以读取数字逻辑与计算机设计莫里斯马诺。

本程序是关于PIC端口初始化，希望对大家有帮助。-IO INITIAL

难得的SD卡SD模式四线制读写源代码，没有文件系统，简单的暴力读写，可以作为开发参考。
