はじめに
こちらの商品を買って使ってみました。sites.google.com
なにができる？
タブレットやノートPCをマクロパッドとして使用できます。以前同じことをやりたくてUSBシリアル変換アダプターとArduino Leonardoを使って自作したことがあります。

それと同じことができました。
Pythonスクリプト
GUIを作りたくてPySide6を使ったスクリプトを書きました。もともとサンプルプログラムを用意してくれているので少し改変しただけです。import sys,time,serial from PySide6 import QtSerialPort from PySide6.QtCore import QSize, QIODevice from PySide6.QtWidgets import QMainWindow, QWidget, QComboBox, QPushButton, QVBoxLayout, QHBoxLayout, QApplication, QSizePolicy ZENHAN=0x35; ENTER=0x28; SPACE=0x2C; BACKSPACE=0x2A; SHIFT=0xE1 CTRL=0xE0; ALT=0xE2; TAB=0x2B; ESC=0x58; WINDOWS=0xE3 SPK={ZENHAN, ENTER, SPACE, BACKSPACE, SHIFT, CTRL, ALT, TAB, ESC, WINDOWS} TBL={'!':[2,0x1E], '"':[2,0x1F], '#':[2,0x20], '$':[2,0x21], '%':[2,0x22], '&':[2,0x23], "'":[2,0x24], '=':[2,0x2D], '-':[0,0x2D], '~':[2,0x2E], '^':[0,0x2E], '|':[2,0x89], '\\':[0,0x89], '`':[2,0x2F], '@':[0,0x2F], '{':[2,0x30], '[':[0,0x30], '}':[2,0x31], ']':[0,0x31], '*':[2,0x34], ':':[0,0x34], '+':[2,0x33], ';':[0,0x33], '<':[2,0x36], ',':[0,0x36], '>':[2,0x37], '.':[0,0x37], '?':[2,0x38], '/':[0,0x38], '_':[2,0x87], '\\':[0,0x87] } TBL[' ']=[0,0x2C] TBL['0']=[0,0x27] #数字(0) for i in range(9): TBL[chr(i+1+48)]=[0,0x1E+i] #数字(1-9) for i in range(26): TBL[chr(i+65)]=[2,0x04+i] #大文字(A-Z) TBL[chr(i+97)]=[0,0x04+i] #小文字(a-z) class Windows(QMainWindow): serial = QtSerialPort.QSerialPort() def __init__(self): super().__init__() self.setFixedSize(QSize(540, 300)) #portの選択 self.port_selector = QComboBox() self.port_selector.setStyleSheet('font: 20px; font-weight: bold') self.port_list = QtSerialPort.QSerialPortInfo.availablePorts() for each_port in self.port_list: self.port_selector.addItem(f'{each_port.portName()}: {each_port.description()}') self.connect_button = QPushButton('connect') self.connect_button.setStyleSheet('font: 20px; font-weight: bold') self.connect_button.clicked.connect(self.connect_push) menu_layout = QHBoxLayout() menu_layout.addWidget(self.port_selector, 3) menu_layout.addWidget(self.connect_button) #portの選択 #ボタンの配置 self.button1 = QPushButton("1") self.button2 = QPushButton("2") self.button3 = QPushButton("3") self.button1.clicked.connect(self.button1_push) self.button1.setEnabled(False) self.button1.setSizePolicy(QSizePolicy.Ignored, QSizePolicy.Ignored) self.button1.setStyleSheet('font: 28px; font-weight: bold') self.button2.clicked.connect(self.button2_push) self.button2.setEnabled(False) self.button2.setSizePolicy(QSizePolicy.Ignored, QSizePolicy.Ignored) self.button2.setStyleSheet('font: 28px; font-weight: bold') self.button3.clicked.connect(self.button3_push) self.button3.setEnabled(False) self.button3.setSizePolicy(QSizePolicy.Ignored, QSizePolicy.Ignored) self.button3.setStyleSheet('font: 28px; font-weight: bold') button_layout = QHBoxLayout() button_layout.addWidget(self.button1) button_layout.addWidget(self.button2) button_layout.addWidget(self.button3) main_layout = QVBoxLayout() main_layout.addLayout(menu_layout) main_layout.addLayout(button_layout) menu_widget = QWidget() menu_widget.setLayout(main_layout) self.setCentralWidget(menu_widget) def connect_push(self): self.connect_button.setEnabled(False) list_index = self.port_selector.currentIndex() self.serial.setPort(self.port_list[list_index]) self.serial.setBaudRate(QtSerialPort.QSerialPort.Baud9600) self.serial.open(QIODevice.WriteOnly) self.button1.setEnabled(True) self.button2.setEnabled(True) self.button3.setEnabled(True) def button1_push(self): self.print('python -m pip install --upgrade pip') def button2_push(self): self.print('--cache-dir python_cache') def button3_push(self): self.print('explorer.exe .') def sendpacket(self,data): self.serial.write(bytes(data)) time.sleep(0.01) #return self.ser.read(7) def push(self,k0,k1,k2=0,k3=0,k4=0,k5=0,k6=0): #print(self.port,": ",hex(k0),hex(k1)) b=[0x57,0xAB,0x00,0x02,0x08,k0,0x00,k1,k2,k3,k4,k5,k6] b.append(sum(b) & 0xff) self.sendpacket(b) b=[0x57,0xAB,0x00,0x02,0x08,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x0c] self.sendpacket(b) def print(self,st): if len(st)<1: return for x in st: if(x in TBL): dat=TBL[x] self.push(dat[0],dat[1]) def write(self,k): if(k in TBL): #通常キーの場合 dat=TBL[k] self.push(dat[0],dat[1]) if(k in SPK): #特殊(装飾)キーの場合 if(k==SHIFT): self.push(0x02,0) return if(k==CTRL): self.push(0x01,0) return self.push(0x00,k) if __name__ == "__main__": app = QApplication([]) ex = Windows() ex.show() app.exec()
