raspberry pi 3 安裝python pyautogui

-

主要安裝步驟

linux 需安裝其他的東西

sudo apt-get install python-tk
sudo apt-get install python3-dev
sudo apt-get install scrot
sudo pip3 install python3-xlib

最後安裝
sudo pip3 install pyautogui


新版的應該是已安裝好以下：
python-tk
python3-dev
scrot

錯誤一

如果直接安裝pyautogui會出現以下的錯誤


表示缺少xlib
只要安裝 python3-xlib完，再安裝pyautogui就可以了

錯誤二

如果像我其他都安裝好了，但是pyautogui還是安裝不成功，出現以下錯誤

那就把
sudo pip3 install pyautogui
改成
sudo xvfb-run pip3 install pyautogui
上網查 xvfb-run 應該是模擬安裝的意思

python pyautogui 簡介

pyautogui 是 python的一個模組，他能控制鍵盤和滑鼠的操作，能利用它做自動化操作，像是用在軟體測試、重複性動作等。 pyautogui 暫停幾秒鐘 >>>pyautogui.PAUSE = 1.5 fail-safe (預設false) 當滑鼠一道螢幕左上角時，觸發 pyautogui 的failsafeexception 異常 >>>pyautogui.FAILSAFE = True 螢幕上的座標軸 (0,0) →→→→(1920,0)    ↓    ↓    ↓    ↓ (0,1080) 取得螢幕解析度 >>>import pyautogui >>>pyautogui.size() (1920, 1080) >>>width, height = pyautogui.size() 滑鼠部分 moveTo(width, height, duration) example移動到(300, 400)位置 pyautogui.moveTo(300, 400)                 #立即到 pyautogui.moveTo(300, 400, duration = 1.5) #花1.5秒移到 moeRel(width, height, duration) 移到相對座標，以當前滑鼠座標為基準點 pyautogui.moveRel(0, 100, duration=0.25) pyautogui.moveRel(-100, 0, duration=0.25) position() 獲得滑鼠當前的座標位置 >>>pyautogui.position() (300, 400) click(width, height, button) 滑鼠點擊 button = 'left', 'middle', 'right'。 pyautogui.click()       ...

android 定時通知(永久長期的) 本篇只講AlarmManager使用

-
本篇使用AlarmManager達到準時執行某程式，跟鬧鐘的方式一樣，我之前用過IntentService、Service、Handler，都不能長期使用。 Servicer簡單缺點整理： IntentService：只要關閉activity背景保存視窗，IntentService背景所執行的程式就被強迫結束，好像可以重開(我沒試過)。 Service、Handler：雖然關閉activity會繼續執行，但他是重新在開啟一次service，這到還好，但當手機螢幕關閉處於待機狀態時，service會停止運作暫停在那邊，等你喚醒再繼續執行，所以用這個加timer做定時通知會整個亂掉，timer會停下來不數了。 AlarmManager主要架構是 跟系統註冊鬧鐘甚麼時間點 → 時間到系統會發送一個鬧鈴 → 你的activity接收那個鬧鈴後執行你的程式 當你註冊好幾個鬧鐘已經晚於現在時間，他會馬上通通都執行完 先建立接收鬧鈴的程式 在Manifest.xml 中加入接收系統鬧鈴 <application> <activity android:name=".MainActivity"> </activity> <!-- 當鬧鈴時間到達時要執行的程式 --> <receiver android:name=".AlarmReceiver"> <intent-filter> <action android:name="activity_app" /> </intent-filter> </receiver> </application> 建立一個class檔，執行接收到鬧鈴後的程式 public class AlarmReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { ...

python nn 聲音辨識 -1 傅立葉轉換

-
辨識環境聲音判斷出這是甚麼聲音 主要想法是用頻域赫茲分布做判斷 首先先錄三種聲音的聲音檔，我每一種聲音重複錄製九個sample，所以有27個wav檔 讀取wav檔案，作正規劃處理，在做傅立葉轉換 一開始由於自己做的fft_domyself() function跟其他聲音處理軟體做出來的不一樣，數值非常小，之後找到有內建的spectrogram() function，使用也是數值很小，最後才想到要20log()，但由於內建的覺得不適合自由調整，所以還是修改自己的function。 import matplotlib.pyplot as plt from scipy.fftpack import fft from scipy.io import wavfile # get the api import numpy as np from scipy import signal import math import pyaudio import wave import time #buf=[] #讀入單一檔案測試 def init(): fs, data = wavfile.read('0106.wav') # load the data b=[(ele/2**16.) for ele in data] # this is 16-bit track, b is now normalized on [-1,1) c = fft(b) # calculate fourier transform (complex numbers list) d = len(c)/2 # you only need half of the fft list (real signal symmetry) plt.subplot(211) plt.plot(b,'b') plt.title('time line') plt.subplot(212) plt.plot(abs(c[:(d-1)]),'r') plt.title('fft') plt.show() return fs, b #取樣率 dat...
