Hi,
can please anybody check SPI1 definition ?

Tring connect display
#define TFT_CS 13// chip select
#define TFT_DC 1 // Display data/command select
#define TFT_BACKLIGHT 0 // Display backlight pin
#define TFT_MOSI 14 // Data out
#define TFT_SCLK 16 // Clock out

this working
Adafruit_ST7789 tft = Adafruit_ST7789(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST);

but this not working
Adafruit_ST7789 tft = Adafruit_ST7789(&SPI1, TFT_CS, TFT_DC, TFT_RST);

not swapped miso/mosi ? I try change in variant.h but not success

Thanks

I've been working at using this to program a Rak4260-dev board using the bastwan as selected board in the Arduino IDE.
As far as I can tell the pins 32 and 33 on the RAK4260 must be hardwired to the ch341-uart converter on the RAK5005 base board.

pin 32 -> PA04
pin 33 -> PA05

But digging deep into core/arduino libraries it seem this library does its own thing : )
as far as pinPeripheral ( xxx ,PIO_SERCOM_ALT) is not supported. How do you handle creating a serial port on sercom alternate pins?

I see reference in the documentation to a Serial Config Menu but must have been dropped?
