Compilation error for BW16-kit about arduino_gfx HOT 10 CLOSED

please get update the latest master branch to check is it ok now

from arduino_gfx.

Hello moononournation!

I updated the library as you recommended.
And I tried to compile the simplest example from the “Arduino GFX library”
"HelloWorld.ino" and got 2 errors.

I’ll give you a complete example so you can see, maybe I’m doing something wrong.
I set the pins of my board according to the example you give for the RTL8720DN
on the page: https://www.instructables.com/ArduinoGFX/

Connection summary:
RTL8720DN -> ILI9341
Vin -> Vcc
GND -> GND
GPIO 18 -> CS
GPIO 2 -> RESET
GPIO 17 -> D/C
GPIO 21(MOSI) -> SDI(MOSI)
GPIO 19(SCK) -> SCK
GPIO 23 -> LED

But still, even with such a simple example, I get two errors !!!!!

^~~~~~~~~
exit status 1
Error compiling for board Ai-Thinker BW16 (RTL8720DN).

And I must say that I looked through the “Arduino_HWSPI.cpp” file, I did not find those lines that are indicated in the errors “Arduino_HWSPI::begin(int32_t, int8_t)” and “SPI_MODE2”.

Best regards, Sergei.

I think you should report to realtek not defined SPI_MODE2

from arduino_gfx.

But there are many examples on the Internet of repeating the wi-fi analyzer on the RTL8720DN, and you too, where everything works fine, how did the wi-fi analyzer work normally before?

from arduino_gfx.

that's why I suggest you report this error to Realtek latest board package have this error.

from arduino_gfx.

Okay, I’ll try to get in touch, but I have a few more questions for you:

You can indicate a specific address where to contact, I received the BW16-kit (RTL8720DN) boards only 2 weeks ago and did not expect to encounter such problems when trying to repeat the finished ones. proven and working examples from the Internet.
Therefore, I simply don’t know where to send my request.
And the second question.
Maybe you can tell me where I can get older software that did not have this error yet.
Since the request itself and its corrections may take some time, and it is not known how long, I would not want to sit and just wait.

from arduino_gfx.

use previous version is a quick solution, you can use board manager select previous version to install

from arduino_gfx.

Can you tell me the address where to send a bug report?

Hello moononournation!
Thank you for your advice, rolling back to an older version really helped.
True, the rollback was not without problems.
I first tried to roll back through the Arduino IDE board manager and the problem with “Arduino GFX Library” went away, but the problem with “lwip_netconf.h” remained, I tried to roll back to a lower version again, after that the “Arduino GFX Library” stopped working altogether.
After several reinstallations, I finally figured out that I need to completely delete the “realtek” folder (C:\Users\User\AppData\Local\Arduino15\packages\realtek) and only after that install the old version through the board manager, as if you were installing it the first time and then everything worked great. It is enough to roll back to version 3.1.6.
I am attaching a photo:

Good to see that.
