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下同一個進程中多個定時器實現。簡單描述下定時器模塊的實現,有一個manager單例類保存所有CTimer對象,開啟一線程運行延遲函數,每次延遲間隔到,掃描保存CTimer的容器,對每個CTimer對象執行減少時間操作,減少到0則執行回調函數。對一次性CTimer,超時則從容器中刪除,循環型的將間隔時間重置,不從容器中移除。 CTimer的start執行將對象插入到manager容器中操作;stop執行將對象從manager容器中刪除的操作;reset執行先刪除,重置間隔,然后再放到容器中,reset不改變CTimer的定時器類型屬性。 代碼來源于CppExplore,感謝博客主的共享。

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.
