In this section we will try to give ideas on how to drive the UART from a PC
|
| 2 |
|
|
besides the simple implementation with RealTerm.
|
| 3 |
|
|
|
| 4 |
|
|
in the software folder of the project archive you will find:
|
| 5 |
|
|
|
| 6 |
|
|
++ rtd_uart_test.bat :
|
| 7 |
|
|
\ copy this bat file inside the RealTerm software folder to load the program (http://realterm.sourceforge.net/)
|
| 8 |
|
|
passing parameter settings (uart port, speed, display size, etc)
|
| 9 |
|
|
\ check "RealTerm_line_commands.txt" in the documentation folder for more parameters
|
| 10 |
|
|
\ loads a file "Hex_commands.bin" (in BINARY format) and sends it over UART
|
| 11 |
|
|
\ known strange behaviour of such method:
|
| 12 |
|
|
> COLS=18 doesn't set the number of columns to 18
|
| 13 |
|
|
> relative paths or paths with "" don't work
|
| 14 |
|
|
|
| 15 |
|
|
++ py_serial_control.py :
|
| 16 |
|
|
\ custom very simple script to read and write the UART with Python (http://www.python.org/doc)
|
| 17 |
|
|
\ uses the pySerial library (http://pyserial.sourceforge.net/)
|
| 18 |
|
|
\ parses human readable parameters and translates them into the correct hex commands
|
| 19 |
|
|
> e.g: >> update --> 0x8000 0x00000000
|
| 20 |
|
|
\ include a basic 'help' menu
|
| 21 |
|
|
\ define your commands
|
| 22 |
|
|
\ DEFINE the number of registers to expect back after an update
|
| 23 |
|
|
\ to be implemented:
|
| 24 |
|
|
> load parameters and commands from files
|
| 25 |
|
|
> improve readback print on screen formatting
|
| 26 |
|
|
> make a generic nregister readout
|
| 27 |
