请教ESPHome 如何点亮ST7789V显示屏

996054544

color:
  - id: my_blue
    red: 0%
    green: 0%
    blue: 100%

spi:
  clk_pin: GPIO2
  mosi_pin: GPIO3

display:
  - platform: ili9xxx
    model: st7789v
    dimensions:
      height: 170
      width: 320
      offset_height: 35
      offset_width: 0
    transform:
      swap_xy: true
      mirror_x: false
      mirror_y: true
    color_order: bgr
    data_rate: 10MHz
    cs_pin: GPIO7
    dc_pin: GPIO11
    reset_pin: GPIO5
    lambda: |-
      it.rectangle(0,  0, it.get_width(), it.get_height(), id(my_blue));
      it.rectangle(0, 20, it.get_width(), it.get_height(), id(my_blue));  
上面是我的示例代码,主控是ESP32C3,显示屏上什么也没有显示,硬件接线是对的,请问是我哪里没设置好吗?

GPIO针脚接线对的，点亮应该没问题，只是这个没有任何内容显示

      it.strftime(5, 5, id(font_12), id(my_blue), TextAlign::TOP_LEFT, "%H:%M:%S", id(time_comp).now());

time:
  - platform: sntp
    id: time_comp

问题解决
主要是修改了这3个参数

dc_pin: 8
reset_pin: 9
spi_mode: MODE2
