自己写的用AVR 单片机产生正弦波.用示波器观察波形很好！

发射芯片nrf24e1的控制字配置，发射子程序 与单片机的通讯-Launch control chip nRF24E1 word configuration, launch communications subroutine with SCM

这是一个用于实现电脑和pic单片机通讯的，通过usb接口的通讯程序！第一部分

JUPITER演示程序，lcd显示图片。-JUPITER demo program, lcd display picture.

此程序为51实验板1602显示字符程序，经典字量少。-This procedure for 1602 show 51 characters board procedures, the classic word less.

PIC18F4550_USB开发原代码，可以给需要用单片机开发USB通信使用参考-PIC18F4550_USB development of the original code, can require the development of USB communication using single-chip reference

音控小车是凌阳大学计划为配合61板的趣味性应用而推出的，以打破传统教育中学习单片机的枯燥性和低效性的现状为目的。此小车采用特定人识别，可通过语音命令对其行使状态进行控制，在小车前进过程中可自行躲避障碍物，为留给用户更大的发挥空间，在我们的电机控制板上留有开关型传感器扩展电路、PWM控制电路以及61板插接口和扩展电源接口，用户可根据自己的创意任意发挥。-noise control car is Sunplus University plans to meet the 39-61 plate application, launched the to break with the traditional education learning SCM boring and ineffective for the purpose of the status quo. This car used to identify a specific person, through voice command for the state to exercise its control, Trolley forward in the process may avoid obstacles, as users leave more room for a, in our motor control boards have expanded switch sensor circuit, PWM control circuit and 61 plate inserted interface and power supply expansion interface, users can own creativity arbitrary play.

实现CAN总线通讯的自测试功能，如果硬件条件具备，也可用来实现CAN控制器之间的通讯。 具体内容见代码中每一句的注释，经调试成功-CAN bus communication realize the self-test function, if hardware conditions are ripe, but also can be used to realize communication between the CAN controller. The specific content of the code, see the Notes of each sentence, after the successful commissioning

单片机调试程序，液晶1602驱动程序，希望对大家有帮助-Single-chip debugger, LCD driver 1602, in the hope that we have to help

I0口作为串行口发送接收函数完美版-I0 mouth as send and receive serial port function perfect version

按键扫描 51单片机加8279 8279通过74LS 138译码器扩展4×4键盘、6位显示器。 由3-8译码器对SL0～SL2译出键扫描线，由另一3-8译码器译出显示器的位扫描线，并采用了编码扫描方式。 为了防止出现重键现象，扫描输出线高位SL3不参加键扫描译码。CPU对8279的监视采用了查询方式，故8279的中断请求信号IRQ悬空未用。 -Scan button 82,798,279 plus 51 single-chip decoder 74LS 138 through the expansion of 4 × 4 keyboard, the display 6. From 3-8 decoder SL0 ~ SL2 translated to the key scanning line, by another 3-8 decoder translated display scan line, and uses code scanning. In order to prevent the emergence of the phenomenon of re-key, scan the output line does not take part in high level SL3 scan decoding keys. CPU on the 8279 surveillance using the query mode, the 8279 interrupt request signal IRQ left unused.
