收音机程序，大家分享一下吧！！！！1 大家也帮忙看看写的对不对...

看到最近大家都关心 usbhost 的实现, 论坛上能找到的代码仅是一些简单的 demo , 完整的源码级的协议层是找不到的 我就贡献一把, 将我前一段时间移植成功的 USBHost 代码奉上 注意事项 1. ohci 层移植自 u-boot-1.3.2-rc3 2. fat 层移植自 gba_nds_fat 3. 本代码只是我产品中的一部分, 使用 Keil RTL 操作系统, 任务为 void task_usb(void) __task 保证完整, 想要跑起来可能需要做些修改与测试-?#39 ??????#39 蠹??脊匦?usbhost 的实现, 论坛上能找??的

是protel的讲义，应该有利于大家的学习-Yes protel lectures, should be conducive to our learning

1.ARM芯片LPC2148的RTC源码 2.ARM芯片LPC2148的DS18B20C驱动源码 3.ARM芯片LPC2148的TIMER0中断驱动源码-LPC2148 chip 1.ARM the RTC source 2.ARM the LPC2148 chip DS18B20C drive LPC2148 chip 3.ARM source of Timer0 interrupt-driven source

采用UART方式0与LM74通信。 用C8051f020的P0.7作片选，主机通过TXD发送时钟信号，实现同步通信,半双工.RXD 作双向数据线.用六位数码管显示LM74采集的温度值-The use of UART communication mode 0 and LM74. P0.7 used for the C8051F020 chip select, host TXD sent through the clock signal, to achieve synchronous communication, half-duplex. RXD for bi-directional data line. With six digital tube display LM74 temperature collected

这是一个有实用价值的制作。可记录 0-17米每秒的风速。可靠性高、架设容易、适用范围广。可存放30.46天的数据，并可保存11个月。也就是说，在12个月内去抄一下数据即可。抄数据的方式是通过手提电脑的串行口。供电方式为太阳能电池及普通电池。-This is a practical value has produced. Record of 0-17 meters per second wind. High reliability, easy to set up, the application scope. 30.46 days to deposit the data, as well as preservation of 11 months. In other words, in the 12 months to what data can be copied. Copied data is through the serial port of portable computers. Power supply for solar cells and normal cells.

本应用笔记描述了一种完全可行且高度灵活的软件应用，使用dsPIC30F 来控制无传感器无刷直流（brushless DC，BLDC）电机。 此软件将dsPIC30F 外设广泛应用于电机控制。所实现的无传感器控制算法特别适用于风扇和泵。-The application notes described a completely feasible and highly flexible software applications to control the use of dsPIC30F Sensorless Brushless DC (brushless DC, BLDC) motor. This software will be widely used in dsPIC30F motor control peripherals. The realization of sensorless control algorithm is particularly applicable to the fan and pump.

液晶屏显示程序，主要对各按键处理做了很好的处理，可随意改动各按键，通讯采用MODBUS ASCII 可以控制台达变频器的起停及速度控制-LCD display program, the main keys to deal with a very good, may be arbitrarily changed the keys, communications using MODBUS ASCII converter can console cease and the speed control
