Error: 'BitOrder' has not been declared, does not name a type Compiling st77** lib example. #81

I tried compiling the Example 'graphicstest' for the Adafruit ST77** TFT LCD driver and got several errors concerning 'BitOrder' not being declared, (BitOrder dataorder = SPI_BITORDER_MSBFIRST) BitOrder _dataOrder;

I used the atmega4809, 48 pin package as board type. Strangely enough, selecting the Arduino Nano Every as the board type DOES compile without error, and they both use the same CPU. This might be an issue with the ADAfruit library, but I can't find the definition for 'BitOrder' in the code.

I tried to install the Adafruit ST7735/ST7789 library from the library manager, and I'm not able to make it build for any AVR platform. Can you post your full error message?

EDIT: I can't find any references to SPI_BITORDER_MSBFIRST in the library source files. What libraries exactly did you install?

I found a reference to SPI_BITORDER_MSBFIRST in the Adafruit Bus IO library.

try adding

typedef enum _BitOrder {
  SPI_BITORDER_MSBFIRST = MSBFIRST,
  SPI_BITORDER_LSBFIRST = LSBFIRST,
} BitOrder;

at the very top of your sketch, before all the #includes

This has been fixed in the Adafruit BusIO library.
