Error message when compiling for Arduino Uno Wifi

[yhellowt]

I have connected my GameDuino to a Arduino Uno Wifi. 

I receive the following error message when compiling the code, eg. HelloWorld, for the Arduino Uno Wifi architecture. 

How can I solve this issue?

Which arduino IDE do you used?, I recommend to you the IDE 1.8.7

Working from IDE 1.8.7 generates the same issue.

I update the GD2.h and wires.h library code with

#if !defined(__DUE__) && !defined(ESP8266) && !defined(ARDUINO_ARCH_STM32L4) && !defined(ARDUINO_ARCH_MEGAAVR)
SPI.setClockDivider(SPI_CLOCK_DIV2);
SPSR = (1 << SPI2X);
#endif

Of course this solved the error message. Unfortunately, after the uploading the code, the screen does not turn on.

I'd check that the SPI pins are in the correct place

If they're not on 11,12,13 then you'll need to either use one of the adapter shields, or make 3 wire hookups, as for the Mega2560:

(I looked, but couldn't find the pinout for the Arduino Uno Wifi online!)

Best of luck!

Thanks for the support!

It seems indeed that the SPI pins are not 11, 12 & 13. I used jumpers to connect the SPI to the ICSP pins. The display works.

I am now having the issue that everything slows down massively only when I read JPGs from the SD Card. It works but takes massive time. Any idea?

[jamesbowman]

Is this Gameduino 2 or 3? Gameduino 2 JPG loading took a few seconds. On Gameduino 3 it's hardware accelerated.

It is a Gameduino 3. It works fine with JPGs on the Arduino Uno. Same code, without JPGs as backgrounds works fine on the Arduino WiFi Rev 2. Similar code with JPGs slows down. Seems to bee something with the clock. Might this be something that needs to be updated in the library?
