ST7920 drive can be realized, the use of 51/52 single

基于PHILIPS LPC2000系列,实现简单的RS232 TO CAN,CAN T0 RS232的数据转换。-Based on PHILIPS LPC2000 series, the realization of a simple RS232 TO CAN, CAN T0 RS232 data conversion.

linux下的jtag仿真器程序，可使用在arm7（44b0，4510，2410等）和arm9上面，可以烧写flash 39lv160等，再不用两个系统不停重启了。-the JTAG Emulator procedures, the use of the ARM7 (44b0, 4510,2410) and arm9 above, 39lv160 burning flash, no longer have to keep two systems resumed.

掌宇公司44b0实验平台的测试程序，共16个程序,包含led,数码管，开关，串口，蜂鸣器，实时时钟，键盘中断，ADC，网卡，PS2键盘，UC/GUI-company 44b0-yu palm experimental test platform, with a total of 16 procedures, including led, digital control switches, serial, buzzers, real-time clock, keyboard interrupt, ADC, Ethernet, PS2 keyboard, UC/GUI

这是以太网芯片W5500的UDP最新例程代码，基于Keil4.72版本，主控芯片为STM32F103RCT6。用户下载并烧录入MCU中Reset后，在PC上用网络调试助手虚拟一个UDP Sever/Client，W5500可以作为UDP Client/Server同PC进行数据通信测试，需注意服务器和客户端的IP及端口设置。W5500是一款全硬件TCP/IP协议栈以太网芯片，代码简单，移植到其他单片机平台非常方便。

MSP430F149键盘输入程序，利用msp430f149单片机的p1端口输入-MSP430F149 keyboard input program, the use of the port input msp430f149 SCM p1

用LPC213X系列的PWM来产生语音。语音数据来源于PC机转换后得到的。最大可以是16位的。 由于是PWM所以输出端口需要低通滤波才能够得到比较干净的声音。 可以经过修改使用LPC2132以上的ARM的D/A来产生。 This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM. -LPC213X series used to generate the PWM voice. Voice data from the PC after the conversion. It is the largest of 16. Because there is PWM output ports need low-pass filter can be relatively clean voice. It has been modified over the use LPC2132 ARM D/A to produce. This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM.

这是周立功的《深入浅出arm7》的书的pdf，包括上下两册，供初学者使用。-This is the week of meritorious service
