Git - Formatting Log Output

Graphs

The --graph option draws an ASCII graph representing the branch structure of the commit history. This is commonly used in conjunction with the --oneline and --decorate commands to make it easier to see which commit belongs to which branch:

git log --graph --oneline --decorate

For a simple repository with just 2 branches, this will produce the following:

*   0e25143 (HEAD, master) Merge branch 'feature'
|\  
| * 16b36c6 Fix a bug in the new feature
| * 23ad9ad Start a new feature
* | ad8621a Fix a critical security issue
|/  
* 400e4b7 Fix typos in the documentation
* 160e224 Add the initial code base

The asterisk shows which branch the commit was on, so the above graph tells us that the 23ad9ad and 16b36c6 commits are on a topic branch and the rest are on the master branch.

While this is a nice option for simple repositories, you’re probably better off with a more full-featured visualization tool like gitk orSourceTree for projects that are heavily branched.

Arduino 切換開關點亮 LED －處理 Bounce 問題

原來機械式開關還存在所謂的「彈跳 (Bounce)」問題解決方式： 1. 延遲時間 (輪詢式) 2. 使用程式庫 Bounce2 官方出了新版的 library Bounce2 參考官方文件作法，調整為 #include <Bounce2.h> #define SERIAL_BAUDRATE 19200 #define LED_PIN 11 #define SWITCH_PIN 7 Bounce bouncer = Bounce(); boolean led_status; void setup() { Serial.begin(SERIAL_BAUDRATE); pinMode(LED_PIN, OUTPUT); pinMode(SWITCH_PIN, INPUT); // After setting up the button, setup the object bouncer.attach(SWITCH_PIN); bouncer.interval(5); led_status = LOW; digitalWrite(LED_PIN, led_status); } void loop() { if(bouncer.update() == true && bouncer.read() == HIGH){ led_status = !led_status; digitalWrite(LED_PIN, led_status); } } 3. 延遲時間 (硬體中斷) 參考資料： 1.
