Waveshare ESP32-S3-LCD-1.85

ESPHome
1

I’m venturing into using a display in ESPHome for the first time, but I’m having no luck. Any pointers are appreciated.

I am using this device:

I’ve tried using similar code as shared in this thread, since they share similar screens: GUITION 1.8” 360x360 ESP32-S3-JC3636W518 Smart Display

I did change out the pin definitions (except for the EXIO reset pin, which I’m not sure how to reference), and used the init sequence I found in the sample code (in esp_lcd_st77916.c).

My current yaml:

If I comment out the lvgl section and flash, the device is available and I can toggle the switch for the backlight, but with the backlight on the screen is just “snow” (I’m not sure if that’s normal). However, if I flash with the lvgl section the screen remains black and the device does not come online.

Any suggestions for what I’m missing?

The LCD reset pin is on an expander so you need to add a component for that - pca9554 I think. Then specify the pin as per the expander docs.

Thanks! That helps a bit, but alas I still get the same results.

I updated the gist, but the new bits I added:

i2c:
  sda: GPIO11
  scl: GPIO10
  scan: true

pca9554:
  - id: 'pca9554a_device'

...
    reset_pin: 
      pca9554: pca9554a_device
      number: 2

Pin 1, not pin 2. They are 0-based in the config.

Hrm, well I tried that, and it still is mostly the same. “Snow” without the display component; wIth the display component, just a dark screen. However, ESPHome shows it as online, and I can ping it. But I cannot connect to the web server and again, all I see is a black screen. So…could be progress?

I haven’t had time to confirm if this is indeed the fix, but try adding a psram section as in this example:

I just set the speed to 40MHz for the initial test, but I’m seeing “Hello World!” on my screen now.

Works! Nice!!!

Thanks much to both of you. I also updated my gist with the working code.

No, thank you!

I’m hoping to get more of this configured, so I’ll update if/when I get more of it working.

Top priority is audio, which I have tried and failed so far, but I was using Arduino framework, and this is using esp-idf, so I’m hoping that makes a difference.

I also have the touchscreen version, and hop to get that working as well.

Thanks, yes, I want to get more of it working as well, including the speakers and microphone at least. I’ll share when/if I have more working additions.

I got sidetracked yesterday playing with the screen. :slight_smile:

Edit: I updated the example to include both mic and speaker that have been confirmed to work. It should also be a complete example with UDP send and receive code.

It’s a bit of a hack, using the microphone event to read and feed the speaker data, but it works.

…

I have been able to stream audio out of the microphone using this configuration:

i2s_audio:
  - id: i2s_in
    i2s_lrclk_pin: GPIO2
    i2s_bclk_pin: GPIO15
  - id: i2s_out
    i2s_lrclk_pin: GPIO38
    i2s_bclk_pin: GPIO48
    #i2s_mclk_pin: GPIO21

microphone:
  - platform: i2s_audio
    id: i2s_microphone
    i2s_audio_id: i2s_in
    i2s_din_pin: GPIO39
    adc_type: external
    pdm: false
    channel: right
    sample_rate: 16000
    bits_per_sample: 16bit
    on_data:
      - lambda: |-
          static std::vector<int16_t> send_buffer;
          static std::vector<uint8_t> recv_buffer(1024);
          static struct sockaddr_in destination = {
            .sin_family = AF_INET,
            .sin_port = htons(12345),
            .sin_addr = { .s_addr = inet_addr("192.168.1.165") }
          };
          static struct sockaddr_in source = {
            .sin_family = AF_INET,
            .sin_port = htons(12346),
            .sin_addr = { .s_addr = INADDR_ANY }
          };
          static int send_sock = ::socket(AF_INET, SOCK_DGRAM, 0);
          static int recv_sock = ::socket(AF_INET, SOCK_DGRAM, 0);
          static bool bound = false;
          if (!bound) {
            int flags = fcntl(recv_sock, F_GETFL, 0);
            fcntl(recv_sock, F_SETFL, flags | O_NONBLOCK);
            bind(recv_sock, (const sockaddr*)&source, sizeof(source));
            bound = true;
          }
          for (uint16_t byte : x) {
            send_buffer.push_back(byte);
          }
          int send_cnt = send_buffer.size();
          if(send_cnt >= 256) {
            ::sendto(send_sock, send_buffer.data(), send_cnt * 2, 0, reinterpret_cast<sockaddr*>(&destination), sizeof(destination));
            send_buffer.clear();
          }
          socklen_t fromlen = sizeof(source);
          int recv_cnt = ::recvfrom(recv_sock, recv_buffer.data(), recv_buffer.size(), 0, reinterpret_cast<sockaddr*>(&source), &fromlen);
          if (recv_cnt > 0) {
            id(i2s_speaker).play(recv_buffer.data(), recv_cnt, 0);
          }

button:
  - platform: template
    name: "Enable Microphone"
    on_press:
      - microphone.capture: i2s_microphone
      - delay: 10s
      - microphone.stop_capture: i2s_microphone
        
speaker:
  - platform: i2s_audio
    id: i2s_speaker
    i2s_audio_id: i2s_out
    i2s_dout_pin: GPIO47
    dac_type: external
    sample_rate: 16000
    bits_per_sample: 16bit
    channel: mono

I suspect the problem that I was having previously was not knowing that I needed to start capture, which is what the button is for.

I got most of this from here: Is there a way to stream audio from one ESPHome to another? - #9 by haforum

I’m currently trying to figure out how to do something similar for the speaker to test it.

Nice. Works for me too, as does the voice assistant.

voice_assistant:
  id: va
  microphone: i2s_microphone
  speaker: i2s_speaker

binary_sensor:
  - platform: gpio
    pin: GPIO6
    name: "Power Button"
    on_press:
      - voice_assistant.start:
          silence_detection: false
    on_release:
      - voice_assistant.stop:                           
  - platform: gpio
    pin: GPIO0
    name: "Boot Button"

Unfortunately it appears media player isn’t compatible with esp-idk. :frowning:
Edit: It does work though if you change to arduino…where the display isn’t compatible.

I updated my gist.

You need to use the external component: speaker media player component; the media player cannot be used under esp-idf. This content will be merged soon.

external_components:
  - source:
      type: git
      url: https://github.com/esphome/voice-kit
      ref: dev
    components:
      - media_player
      - nabu
      - voice_assistant
media_player:
  - platform: nabu
    id: nabu_media_player

    speaker:
    sample_rate: 48000
    volume_increment: 0.05
    volume_min: 0.1

Works perfectly, thanks!

I had been trying to read/play from the tf card, without any luck. With a working media player, that is less necessary.

I was able to get the font and compile the code. Working now, great work!! I was able to get touchscreen working as well, was working on debounce when I read your reply.

On another topic, I bought this display to make a gauge for my car and had no luck with arduino. Whould you possibly have working arduino code for this display? Just a sample to get something on the display.

Thanks again for your reply.

There is sample code in the link on my first post, but I could not get it to compile in Arduino.

I’ve uploaded a new revision with working gyro:

I have a gauge in my latest revision!
