键盘去抖动CPLD设计经过验证,可以直接用数码管显示,同时也希望大家给于新想法-CPLD design of the keyboard to jitter verified, you can directly use digital tube display, but also hope that the new ideas to the U.S.

基于89C52+T6963C的液晶驱动程序,可以显示16*16汉字32个,8*16点阵ASC,8*8点阵ASC,绘制直线等--A LCD driver program based on 89C52+T6963C. it could display 32 Chinese characters(16* 16), 8*16 lattice ASC, 8* 8 lattice ASC, straight lines and etc.

STM32 SPI互通信(DMA) V3.5 两个STM32的SPI接口通信，一个做从机，一个做主机，DMA方式，速度飞快。

A Simple isochronous transfer. Reads 8051 ports A,B and C, and continuously sends a five byte packet over EP8IN:

经过定点优化的G723、G729的codec In case you do not want to install IPP, then you"ll get twice better performance out of ITU-T code if you build it with GCC 4.5 or Intel CC with LTO/IPO enabled. Still, even with ICC, it is 10x slower than IPP - 30ms vs 3ms of processor time to encode one second of G.729 audio on modern hardware. G.723 is around 100ms. GCC with LTO is 2x slower than ICC. For ITU-T code, a Core2 class processor is recommended.

protel转pads的工具，原理图和PCB都可以直接进行转换-Protel to pads of the tool, schematic diagram and PCB can be directly converted

电子时钟的设计： 要求： 设计一个电子时钟。 要求可以显示时、分、秒。 用户可以设置时间。-Electronic clock design: requirements: design of an electronic clock. Required to display hours, minutes and seconds. Users can set the time.

使用凌阳61单片机和1302时间芯片完成时钟功能并使用CH451LS芯片显示（程序中只在0号LED上显示秒）。是使用时，main.c是1302时间芯片的驱动，CH451LS0811.h是简单CH451LS芯片驱动。-The use of Sunplus 61-chip MCU and 1302 hours to complete and use the clock function CH451LS chip display (program only in its LED display 0 seconds). Is used, main.c is the 1302 driver chip time, CH451LS0811.h is simple chip CH451LS drive.

该源代码采用的非接触式读卡协议是14443A，可以读写IC卡的各个扇区，还能做加值减值处理，该工程所使用的主控单片机是ＳＴＣ８９Ｃ５８ＲＤ＋，射频读卡芯片用的是ＦＭ１７０２
