8位数码管动态扫描显示实验(显示不用库函数) *显示用指针直接访问GPIO端口的输出寄存器，形式GPIOD->ODR *延时delay_nms(5)时，显示不闪烁 *74HC138 A--P2.2--PE.0 B--P2.3--PE.1 C--P2.4--PE.2 *74HC573 D0~D7---PD[0..7] LE---PE.3 *by 追梦 2011-4-3(8-bit digital dynamic scan showed that the experimental (show no library function)* Display a pointer to directly access GPIO port output register, form GPIOD-> ODR* delay delay_nms (5), the display does not blink* 74HC138 A- P2. 2- PE.0 B- P2.3- PE.1 C- P2.4- PE.2* 74HC573 D0 ~ D7--- PD [0 .. 7] LE--- PE.3* by Dream 2011-4-3)

bootloader 移植涉及到： 移植环境 .移植技巧 等适用于s3c2440等系列(bootloader remov use to s3c2440)

说明：  stm32103基础程序、 led流水灯、2 SysTick中断、3 SysTick查询、3 SysTick查询（二）、4 GPIO按键输入(Stm32103 basic procedures, LED water light, 2 SysTick interrupt, 3 SysTick query, 3 SysTick query (two), 4 GPIO key input)

It draws on principal component analysis algorithm (PCA), ICA (Principal Component Analysis) algorithm and procedures, Achieve a grayscale image and further control for video surveillance.

介绍高速PCM-FM数字信号接收机的硬件平台设计与实现，主要应用芯片是3c120 (Introduce high-speed digital signal PCM-FM receiver hardware platform design and implementation, the main application chip is 3c120)

基于STM32的SI4463的程序，分为收发两个部分，可变数据长度，可以设置发射功率，带RSSI(The SI4463 based STM32 program, divided into two parts transceivers, variable data length, you can set the transmit power, with RSSI)
