In this section we will try to give ideas on how to drive the UART from a PC

besides the simple implementation with RealTerm.

in the software folder of the project archive you will find:

++ rtd_uart_test.bat :

 \ copy this bat file inside the RealTerm software folder to load the program (http://realterm.sourceforge.net/)

   passing parameter settings (uart port, speed, display size, etc)

 \ check "RealTerm_line_commands.txt" in the documentation folder for more parameters

 \ loads a file "Hex_commands.bin" (in BINARY format) and sends it over UART

 \ known strange behaviour of such method:

   > COLS=18 doesn't set the number of columns to 18

   > relative paths or paths with "" don't work

++ py_serial_control.py :

 \ custom very simple script to read and write the UART with Python (http://www.python.org/doc)

 \ uses the pySerial library (http://pyserial.sourceforge.net/)

   > parses human readable parameters and translates them into the correct hex commands

     e.g: >> update --> 0x8000 0x00000000

     include a basic 'help' menu

 \ Customize your script

   > define your commands

   > DEFINE the number of registers to expect back after an update

 \ Browse to you script folder

   > from a shell type: python py_serial_control.py

   > enjoy ! :)

 \ to be implemented:

   > load parameters and commands from files

   > improve readback print on screen formatting

   > make a generic nregister readout

py_serial il Linux friendly! :)

Tested on Ubuntu 10.04 LTS
