1. DAC conversion trigger conditions. There are two trigger conditions. One is to write the value you want to convert to the dacn_chxdata register, provided that you need to enable the DAC first. Or write the value you want to convert to the

The former is used for the minimum spanning tree, and the latter is used for the single-source minimum path search. Both of them are merged by maintaining the current "minimum" information in the queue of the nodes to be processed: The former

From the beginning of 2011 into the mobile game industry to now two years, a start to use cocos2d-iphone, and later into a cocos2d-x, experienced the explosive development of mobile phone era, it can be said that the middle has experienced a lot of

      The current time is returned in double-character encapsulation. The bitfield is as follows: Bit31: 25 years (0 ~ 127) (starting from 1980) bit24: 21 months (1 ~ 12) bit20: 16 (1 ~ 31) bit15: 11 hours (0 ~ 23) bit10: 5 minutes (0 ~ 59) bit4:

/*************************************** ************LETimer Application Example 1: LETimer One-shot ModeExplanation: The timer runs as long as REP0! = 0.REP0 is decremented at each timer underflow.Note: After LETimer is finished, it stops

Such? The following describes the basic introduction and basic operations of the watchdog. In general, it is relatively simple. Unlike other MCU, efm32 wdt cannot be used as a timer. If the watchdog overflows, the system will reset. At the same time,

I remember that I used EFM32 to test the power consumption when the 32 Khz clock speed was used. But I tried to repeat the test records a few days ago to find that I didn't know whether I did the test or didn't leave any data, it cannot be found.

The most basic routine of LEUart: Hardware preparation: tg stk, il-art0, Tx: PD4, Rx: PD5. tg stk's 20pin expansion port already has these two IO ports: 12Pin (PD4) and 14Pin (PD5 ). Software routine: # Include # Include # Include "efm32.h"# Include

If you want to measure the execution time of a function, how can this problem be solved? I think you should all have your own methods. For me, as long as there is an oscilloscope, I must use GPIO flip and then use the oscilloscope measurement method.

The input positive integer n requires that the matrix of n x n be printed. For example, if n = 4, the output is as follows: 10 11 12 1 9 16 13 2 8 15 14 3 7 6 5 4 #include #include #include int a[10][10];int main(){ int top, bottom, left, right,

  Sort the natural numbers between 1-N in full order. The Code is as follows:     # Define N 6 # define full-1 // complete void test_row () {int num [N]; // The array bool use [N] to be sorted; // number of records already arranged for (int K = 0; k

In the past, GDB debugging was used only to debug a single file. During DHCP secondary relay, gdb debugging was required for the entire project. I found that I could not! Now, I am able to share it with you on my blog. The following describes how

Let's talk about the queue today. I have known the queue for a long time, but it has never been used. It is the basic data structure. After thinking about Baidu and google for a while, I chose loop queue. We can learn from Baidu: Imagine a vector

I used qt4 + mplayer to use a player. It seems like adding a shell is boring. My classmates also told me that mplayer is not so easy to do. I still remember this sentence until now. At that time, we learned linux together and felt that it was good

The pointer in c is very important, but after studying c for so long, I don't know how to use the pointer array pointing to the function. In fact, it is similar to using the function pointer. We can create an interesting structure to point to the

A few days ago, I saw a discussion post on map on the forum. This article mainly discusses how to avoid using the underlying memory pool mechanism of map! Some people say that the map distributor (Allocator) can be customized to achieve the goal. Is
