根據視窗寬度,動態調整google adsense廣告大小

原本最笨的方法, 就是透過display:none
但實在太遜而且違反google建議, 所以跳過

所以我就想自己修改javascript, 根據screen width 之類
這個網址有列出一些可用的變數, 列在下方:

function GetWidth()  {          var x = 0;          if (self.innerHeight)          {                  x = self.innerWidth;          }          else if (document.documentElement && document.documentElement.clientHeight)          {                  x = document.documentElement.clientWidth;          }          else if (document.body)          {                  x = document.body.clientWidth;          }          return x;  }  function GetHeight()  {          var y = 0;          if (self.innerHeight)          {                  y = self.innerHeight;          }          else if (document.documentElement && document.documentElement.clientHeight)          {                  y = document.documentElement.clientHeight;          }          else if (document.body)          {                  y = document.body.clientHeight;          }          return y;  }

但改了改都不優, 隨興看看google說明,
原來其實google已經寫了基本範例, 可以參考

我一開始誤會了, 以為一個ID只能出現一個大小
實際上是一個ID可以根據你餵給它的width與height去動態變化
我的程式碼如下:

<style type="text/css">.adslot_1 { width: 234px; height: 60px; }  /* 半橫幅*/@media (min-width:768px) { .adslot_1 { width: 468px; height: 60px; } } /* 中橫幅*/@media (min-width:960px) { .adslot_1 { width: 728px; height: 90px; } } /* 大橫幅*/</style><script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script><ins class="adsbygoogle adslot_1" style="display:inline-block;" data-ad-client="YOUR_AD_CLIENT_ID" data-ad-slot="YOUR_AD_SLOT_ID"></ins><script>(adsbygoogle = window.adsbygoogle || []).push({});</script>

基於STM32 加入LCM 16*2 display (HD44780)

最近弄一個產品, 處理器是ARM STM32f10,
其中計畫加入一個簡單的顯示螢幕, 可以讓使用者知道目前系統的資訊
於是找了一個16行*2列的螢幕,
裡面使用到的是HD44780的chip吧, 大概長這樣

這個網站有基本的介紹與sample code (C語言)
** http://www.eeherald.com/section/design-guide/sample_lcd_c_programs.html

這個網站也有程式可看, 但不幸的是他寫的似乎是給8051那類的IC使用
但好處是可以將這些sample code互相比較, 找出同異
** http://www.microcontroller-project.com/alphanumeric-keypad-with-16×2-lcd.html

推薦!! 這個網址的說明是最清楚的
程式碼也是寫最棒的(for 4-bits), 還有影片分享
但有個小小錯誤需要改, 自己改吧~
** http://myactivities-mazen.blogspot.tw/2013/09/controlling-216-lcd-with-stm32f4.html

這篇寫得很詳細, 每個步驟都說明
可以study一下~

以下分享從Mazen得到,
修改成 for 8-bits的版本
Thanks Mazen!

STM32 透過ADC_GetFlagStatus 知道 EOC狀態並讀值

其實網路隨意google一下就很多資料

uint16_t readADC1(void) {  uint16_t value;  //ADC_RegularChannelConfig(ADC1, channel, 1, ADC_SampleTime_55Cycles5); // Start the conversion  ADC_SoftwareStartConvCmd(ADC1, ENABLE);   // Wait until conversion completion  while(ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC) == RESET);  ADC_ClearFlag(ADC1, ADC_FLAG_EOC); // Get the conversion value  value = ADC_GetConversionValue(ADC1);  ADC_SoftwareStartConvCmd(ADC1, DISABLE); return value;}

void AdcPro(void){ static uint16_t buf[SAMP_COUNT]; static uint8_t write; uint32_t sum; uint8_t i; //buf[write] = ADC_GetConversionValue(ADC1); 原本直接讀取資料   buf[write] = readADC1();  if (++write >= SAMP_COUNT) {  write = 0; } sum = 0; for (i = 0; i < SAMP_COUNT; i++) {  sum += buf[i]; } g_usAdcValue = sum / SAMP_COUNT; /* 取平均 */ //ADC_SoftwareStartConvCmd(ADC1, ENABLE); /* 原本先為下次使用而enable */}

如何在部落格加入code 區域 (修改css)

可以在各種部落格裡面看到許多將程式碼加入文章裡

其實只要幾個步驟就可以完成了

也就是修改css, 將下面這一段加入CSS就好啦

pre { padding: 10px 5px 10px 22px; margin: 10px 15px; border: 1px solid #CCC; font:13px/120% 'Courier New'; letter-spacing: 0.07em; background: #F5F5F5 url(https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6r-beClagoumej1FnptO1ZkMGkgzGr5q86AlJhe4OQ15lEdwYy6lCIVyJbohqe4-QzLfwEeLJMJDbqKQX1UtZ3WGn1Gb3vGVOQfZruUU-kKdvWT4LQX8pjRPIFS_6TpAOHpYYqZlFAmg/s1600/code.gif) no-repeat scroll left top;  text-align: justify; overflow: auto; color:#333;}

完成後, 之後發表文章時
請記得在你要發布的程式碼加入 pre tag 如下:

<pre> 程式碼 </pre>
