ATmega128 not supported ? #20

Open Greece2 opened 3 years ago

Greece2 commented 3 years ago

As the lib is using the hardware-SPI, it seems it is not working with the ATmega128. The SPI-pins are: MOSI : PB2 -> 10 MISO: PB3 -> 11 SCK: PB1 -> 9 SS: PB0 -> 8

Any chance to integrate that into the lib? Or can one use the "User_Setup.h" to define these pins? Or the "fast_pin.h" ?

Best regards and thanks for the support !

Here part of the compiler's output:

\libraries\TFT_ILI9341-master/TFT_FastPin.h:479:2: warning: #warning "No pin/port mappings found, pin access will be slightly slower. See fastpin.h for info." [-Wcpp]

warning "No pin/port mappings found, pin access will be slightly slower. See fastpin.h for info."

I suspect you are right in that the fast pin macros do not support that processor.

Could that be fixed? The Mega64, 1281, 2561 have the same pinout. Thanks !

No chance at all ?
The lib is such a great tool ! Well, would be ...

The library uses fastpin, this template library is from FastLED http://fastled.io

I do not know what changes would be needed but it could be that the FastLED library has been updated to include the ATmega128?

Thanks for your feedback, I'll check that out.

Have a good time and stay safe !

@Greece2 if you are using megacore, add below section to TFT_Fastpin.h file and you are good to go.
