Cannot create SPI instance on ESP32 S3 #211
Description
I am using an ESP32 S3 with PSRAM 8 MB and flash 16 MB. I want to test the LVGL on ST 7789(240*240) but I am seeing this error when I am creating an SPI instance in thonny.
from machine import SPI, Pin
from micropython import const
import lcd_bus
import st7789
import lvgl
_WIDTH = const(240)
_HEIGHT = const(240)
_SPI_HOST = const(2)
_SPI_SCK = const(10)
_SPI_MOSI = const(11)
_SPI_MISO = const(12)
_LCD_FREQ = const(400_000)
_LCD_DC = const(8)
_LCD_CS = const(9)
_LCD_RST = const(14)
_LCD_BACKLIGHT = const(2)
spi_bus = SPI(
_SPI_HOST,
_LCD_FREQ,
mosi=_SPI_MOSI,
miso=_SPI_MISO,
sck=_SPI_SCK,
cs=_LCD_CS
)
display_bus = lcd_bus.SPIBus(
spi_bus=spi_bus,
freq=_LCD_FREQ,
dc=_LCD_DC,
cs=_LCD_CS
)
display = st7789.ST7789(
data_bus=display_bus,
display_width=_WIDTH,
display_height=_HEIGHT,
backlight_pin=_BL,
color_space=lv.COLOR_FORMAT.RGB565,
color_byte_order=st7796.BYTE_ORDER_RGB,
rgb565_byte_swap=True,
)
MPY: soft reboot
Traceback (most recent call last):

TypeError: can't create 'SPI' instances
Traceback (most recent call last):

I am building with this command:
python3 make.py esp32 BOARD=ESP32_GENERIC_S3 BOARD_VARIANT=SPIRAM_OCT DISPLAY=st7789 INDEV=gt911 --flash-size=16
I even tried using SoftSPI that worked with the compilation but I started getting memory initialization errors.I have tried to resolve those issues as said in the issue#66(#66) but it didn't worked for me.
Thank you!
