not spout esp32c3 HW SPI?

[wx85105157]

Arduino board: ESP-C3-13-Kit

Arduino IDE version (found in Arduino -> About Arduino menu): 1.8.19

List the steps to reproduce the problem below (if possible attach a sketch or
copy the sketch code in too):
test graphicstest.ino

#define TFT_CS 1
#define TFT_RST -1
#define TFT_DC 0
#define TFT_MOSI 2 // Data out
#define TFT_SCLK 6 // Clock out
Adafruit_ST7789 tft = Adafruit_ST7789(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST);
it will work,but slow.

Adafruit_ST7789 tft = Adafruit_ST7789(TFT_CS, TFT_DC, TFT_RST);
use this code nothing happend.
GPIO2 is HW spi MOSI
GPIO6 is HW spi SCK

Discovered using a logic analyzer，GPIO4 use by HW_SPI_SCK,GPIO6 use by HW_SPI_MOSI.
It's not match datasheet default pin func,

[wx85105157]

After line 582 of the Adafruit_SPITFT.cpp file:
if (!freq)
freq = DEFAULT_SPI_FREQ; // If no freq specified, use default
Add the following code:
freq = 10000000;

After line 639:
hwspi._spi->begin();
Add the following code:
pinMode(3, OUTPUT);//spi clk
pinMode(4, OUTPUT);//spi mosi
gpio_matrix_out(3, 63, false, false);//spi clk
gpio_matrix_out(4, 65, false, false);//spi mosi
gpio_matrix_out(5, 0x100, false, false);
gpio_matrix_out(6, 0x100, false, false);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);

The LCD works perfectly on the hardware spi.

can you try again with the 2.0.3 ESP for arduino ide release?
