利用 python 經由 serial port 輸出資料

Python 需安裝 Python Serial Port Extension
  https://pypi.python.org/pypi/pyserial

安裝方式:
. 下載 pyserial-3.0.1.tar.gz
. 解開 pyserial-3.0.1.tar.gz
. 進入解開壓縮檔的目錄下, 執行:

  python setup.py install

開始寫程式:

# coding=UTF-8

import time
import serial


ptn = [0xAA,0x50,0x60,0x70]

def main():
   
    ser = serial.Serial('COM3', 2400, timeout=0.5)
    ary = bytearray(ptn)
    ser.write(ary)
    time.sleep(0.1)
    ser.close()   

if __name__ == "__main__":
    main()

Energia : using hardware UART

Using LaunchPad MSP-EXP430G2
MCU: M430G2553

problem:
Serial Monitor can't get the data from LaunchPad

Solution:
  Connecting to the USB2.0 hub port instead of connecting to USB3.0 port. If it still not works, trying another USB2.0 hub port.


使用 LaunchPad 時, Serial Monitor 一直無法看到 UART 傳來的資料.
後來使用 USB2.0 hub 連接 LaunchPad , Serial Monitor 就可收到 UART 的資料.
