请假几个关于esp32接显示器的问题

fallendawn

我想在esp32上的显示器可以显示homeassistant里其他信息 用esphome
目前配置是这样的

sensor:
  - platform: homeassistant
    entity_id: sensor.bedroom_humidity
    id : id_bedroom_humidity
    internal: true
  - platform: homeassistant
    entity_id: sensor.bedroom_temperature
    id : id_bedroom_temperature
    internal: true

binary_sensor:

  - platform: homeassistant
    entity_id: light.bedroom_light_1
    id : id_bedroom_light_1
    internal: true
    
  - platform: status
    name: "Node Status"
    id: system_status

switch:
  - platform: gpio
    pin: GPIO4
    name: "Backlight"
    id: backlight

spi:
  clk_pin: GPIO18
  mosi_pin: GPIO19

display:
  - platform: st7789v
    backlight_pin: GPIO4
    cs_pin: GPIO5
    dc_pin: GPIO16
    reset_pin: GPIO23
    rotation: 270
    id: ttdisplay
    pages:
      - id: page1
        lambda: |-

          it.printf(50, 75, id(helvetica_24), id(my_yellow), TextAlign::CENTER, "%.1f%%", id(id_bedroom_humidity).state);
          it.printf(50, 95, id(helvetica_24), id(my_yellow), TextAlign::CENTER, "%.1f°" , id(id_bedroom_temperature).state);
          
          if (id(id_bedroom_light_1).state){
            it.printf(100, 115, id(helvetica_24), id(my_yellow), TextAlign::CENTER,"Light State: ON");
          }
          else {
            it.printf(100, 115, id(helvetica_24), id(my_yellow), TextAlign::CENTER,"Light State: OFF");
          }
          
          if (id(system_status).state) {
            it.print(235, 5, id(helvetica_12), id(my_green), TextAlign::TOP_RIGHT, "Online");
          }
          else {
            it.print(235, 5, id(helvetica_12), id(my_red), TextAlign::TOP_RIGHT, "Offline");
          }
      - id: page2
        lambda: |-
          it.image(0, 0, id(my_image));

复制代码

关键是这两行


it.printf(50, 75, id(helvetica_24), id(my_yellow), TextAlign::CENTER, "%.1f%%", id(id_bedroom_humidity).state);
it.printf(50, 95, id(helvetica_24), id(my_yellow), TextAlign::CENTER, "%.1f°" , id(id_bedroom_temperature).state);


我只需要整数 然后我写成%d 屏幕上就显示很长一串数字   %.1f 是可以正常显示 但是总有个零
顺便问下有没有现成的显示各种数据的例子 因为我以后可能还要显示其他的数据
比如 温度湿度啊 监控的情况啊 报警啊之类的

ctrl

%.0f  即可
esphome官网有说明
