Errors compiling the firmware code

[py2oc]

I've got some errors trying to compiling the code through Arduino IDE.
I'm newbie on C++ programming and need some help to understand why the errors.
Looks like a function is called multiple times with different parameters.

D:\Temp\rdz_ttgo_sonde-devel\RX_FSK\src\Display.cpp: In member function 'virtual void ILI9225Display::setFont(uint8_t)':
D:\Temp\rdz_ttgo_sonde-devel\RX_FSK\src\Display.cpp:534:27: error: call of overloaded 'setFont(NULL)' is ambiguous
case 0: tft->setFont(NULL); tft->setTextSize(1); break;

You might go back to the previous version of the Arduino_GFX_Library. v1.1.8 should be ok

Or, I tried to make a small change that should fix this problem. In devel branch, but untested.

The small change does not work on Linux, due to another problem with the new gfx library version (see moononournation/Arduino_GFX#138). So I am not testing it right now. It might be ok on Windows or MacOS

But the downgrade to 1.1.8 should be fine.

Hi Hansi.

Downgrading the Arduino_GFX library to v1.1.8 makes the compilation work.
Got few warnings but compiled successfully.
Thanks for help.
