报时小闹钟 本程序是一个用汇编编的精致的图形时钟，运行时双击clock图标即可， 钟表显示的时间为本机系统的时间。 　　按b键可扩大画面 ；按s键可缩小画面；按c键可改变颜色；按e键可听音乐； 按q键退出本程序.

本例展示了如何利用外设TIM2来产生四路频率不同的信号。 TIM2时钟设置为36MHz，预分频设置为2，使用输出比较-翻转模式（Output Compare Toggle Mode）。 TIM2计数器时钟可表达为：TIM2 counter clock = TIMxCLK / (Prescaler +1) = 12 MHz 设置TIM2_CCR1寄存器值为32768，则CC1更新频率为TIM2计数器时钟频率除以CCR1寄存 ...

本例展示了如何设置TIM工作在输出比较-非主动模式（Output Compare Inactive mode），并产生相应的中断。 TIM2时钟设置为36MHz，预分频设置为35999，TIM2计数器时钟可表达为： TIM2 counter clock = TIMxCLK / (Prescaler +1) = 1 KHz 设置TIM2_CCR1寄存器值为1000， CCR1寄存器值1000除以TIM2计数器时钟频率1KHz，为1000 ...

Genetic Algorithm example using Java You have 10 cards numbered 1 to 10. You have to divide them into 2 piles so that: The sum of the first pile is as close as possible to 36 and the product of all in second pile is as close as poss to 360.

This is GPS in matlab calculatePseudoranges finds relative pseudoranges for all satellites listed in CHANNELLIST at the specified millisecond of the processed signal. The pseudoranges contain unknown receiver clock offset. It can be found by the least squares position search procedure.
