D169 Demo - DMA0 Repeated Burst to-from RAM, Software Trigger Description A 32 byte block from 220h-240h is transfered to 240h-260h using DMA0 in a burst block using software DMAREQ trigger. After each transfer, source, destination and DMA size are RESET to inital software setting because DMA transfer mode 5 is used. P1.0 is toggled durring DMA transfer only for demonstration purposes. ** RAM location 0x220 - 0x260 used - always make sure no compiler conflict ** ACLK= n/a, MCLK= SMCLK= default DCO ~ 800k

The VGA example generates a 320x240 diffusion-limited-aggregation (DLA) on Altera DE2 board. A DLA is a clump formed by sticky particles adhering to an existing structure. In this design, we start with one pixel at the center of the screen and allow a random walker to bounce around the screen until it hits the pixel at the center. It then sticks and a new walker is started randomly at one of the 4 corners of the screen. The random number generators for x and y steps are XOR feedback shift registers (see also Hamblen, Appendix A). The VGA driver, PLL, and RESET controller from the DE2 CDROM are necessary to compile this example. Note that you must push KEY0 to start the state machine.

linux下同一个进程中多个定时器实现。简单描述下定时器模块的实现,有一个manager单例类保存所有CTimer对象,开启一线程运行延迟函数,每次延迟间隔到,扫描保存CTimer的容器,对每个CTimer对象执行减少时间操作,减少到0则执行回调函数。对一次性CTimer,超时则从容器中删除,循环型的将间隔时间重置,不从容器中移除。 CTimer的start执行将对象插入到manager容器中操作;stop执行将对象从manager容器中删除的操作;RESET执行先删除,重置间隔,然后再放到容器中,RESET不改变CTimer的定时器类型属性。 代码来源于CppExplore,感谢博客主的共享。

DESCRIPTION The DCP0105 family is a series of high efficiency, 5V input isolated DC/DC converters. In addition to 1W nominal galvanically isolated output power capability, the range of DC/DCs are also fully synchronizable. The devices feature thermal shutdown, and overload protection is implemented via watchdog circuitry. Advanced power-on RESET techniques give superior RESET performance and the devices will start into any capacitive load up to full power output. The DCP0105 family is implemented in standard- molded IC packaging, giving outlines suitable for high volume assembly.
