IDW01M1 filesystem updater

This repository contains python script and serial passthrough program for STM32
Nucleo. Python script uploads HTML/CSS/JS files to the external Flash memory of
the Wi-Fi expansion board.

Wi-Fi expansion board is connected to the Nucleo board which is connected to a
PC. I should mention that can be used without Necleo board. What is needed is
just serial interface to the Wi-Fi board, therefore, you can
connect IDW01M1 directly to a serial <-> USB adapter.

Instruction

1. Connect Wi-Fi expansion board to the Nucleo and connect it to the PC
2. Compile and upload src/main.cpp program (I used platformio to manage my
   project)
3. Open serial monitor on your PC (for example: GtkTerm (Linux), Arduino IDE
   (windows))
4. Press reset button on your board. After that you should see some initial
   messages of the Nucleo application.

==========================================================
Communication with the Wi-Fi board
==========================================================
Enter passthrogh mode:

1. Now we should test that communication is working correctly. If you type AT
   command you should get OK response.

==========================================================
Communication with the Wi-Fi board
==========================================================
Enter passthrogh mode:
AT
OK

This command do nothing but let us know that communication is working. Now
you can close the serial monitor.

1. Next, we need to configure Python script.
