This Project can not work on esp32C3

MOSI ： GPIO10 SCLK ：GPIO7 CS：-1 DC：GPIO1 RESET：GPIO3 BL： GPIO0

Can anyone help me check it，Thanks！

Why CS:-1？

You need to use CS gpio.

If you don't use CS gpio, you should always set CS of TFT to LOW.

Thanks for your reply，CS GPIO has connect to GND on my board

For some reason, there are development boards that cannot use GPIO06, GPIO08, GPIO09, GPIO19 for SPI clock pins. According to the ESP32C3 specifications, these pins can also be used as SPI clocks. I used a raw ESP-C3-13 to verify that these pins could be used as SPI clocks.

Try to change SPI Clock pin.
