Telosb serial port test-tinyos2.1.1

Telosb has two serial port: UART 0 and UART 1. The default setting is UART1.
When doing the write or read operation, data will go through FT232BM chip, which is a USB-serial converter chip, and then upload to PC.

First, I will introduce the 'make' command

1)make [platform]: this command will compile nesc code that could run on certain platform such as telosb or mica. You need to cd to the code directory.

eg: make telosb; make mica

2)make [platform] reinstall: this command will download the code into the platform

3)make [platform] install: this command is equal to first run 'make [platform]' then 'make [platform] reinstall'. Of course, if there is any error when doing the 'make [platform]', it will not go to 'make [platform] reinstall'.

4)make clean: clean the file or directory the above compile command generate.

Then you can run 'java net.tinyos.tools.Listen -comm serial@/dev/ttyUSB0:telosb'
ttyUSBx could change, you can check the port with 'motelist'

If the java env and PATH is right, you will get
serial@/dev/ttyUSB0:115200: resynchronising

this means java is ok, and it is waiting the data. But it could receive anything.
We need to go to /apps/tests/TestSerial
'make telosb install'
Then try the serial listen again, it will say
:-) java net.tinyos.tools.Listen -comm serial@/dev/ttyUSB0:telosb

Telosb communicate with PC through support/sdk/java and support/sdk/c, we could use java or c to do the communication. Also, we could use python.

java net.tinyos.tools.Listen -comm serial@/dev/ttyUSB0:telosb

This command use java to implement the listen of serial port. The baud rate of telosb is 115200.

Tomorrow I will study the serial port of telosb both in hardware and software.

The cable that connect microUSB port to USB male port is still on delivery...
I will debug telosb serial port and android port separately before I get the cable.
