James Fan / Mbed 2 deprecated RPC_USBSerial

RPC over USB serial testing step by step

Dependencies:   mbed-rpc mbed

RPC over usbserial testing with python step by step ( tested on KL25Z on 29 Aug 2013).

1. Get start - mBed firmware installation.

• http://mbed.org/platforms/KL25Z/

mBed firmware.

http://mbed.org/media/uploads/samux/mbed_if_v2.0_frdm_kl25z.s19

2. Install RPC_USBSerial into KL25Z.

• Register into mbed.org;
• Select platform KL25Z in compiler;
• Import program, Compile, download RPC_USBSerial.bin to PC;
• Save RPC_USBSerial_KL25Z.bin to MBED drive;

3. Install mbed usbserial driver to PC.

• Serial Communication with a PC;

http://mbed.org/handbook/SerialPC;

• Windows serial configuration.

http://mbed.org/handbook/Windows-serial-configuration

Find COM Port name at:

• Control Panel
• > Syetem
• > Hardware
• > Device Manager
• > Ports(COM & LPT)
• > Mbed Virtual Serial Port(COM?) (My one is "COM11" in picture below)

4. Install Python and Pyserial

• install python 2.7
• install pyserial http://sourceforge.net/projects/pyserial/files/pyserial/2.5/pyserial-2.5.win32.exe/download

5. Have fun.

• Modify Port number in serial_raw_rpc_test.py.txt
• Copy/Paste from serial_raw_rpc_test.py.txt to python (command line);
• Copy and run one line at a time to have real fun;
