pcb文件用什么打开呢

Hi, I tried to build the factory_demo however it failss with:

/home//esp/esp-idf/components/freertos/FreeRTOS-Kernel/portable/port_common.c:134: undefined reference to `app_main'
collect2: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.
ninja failed with exit code 1

In file: port_common.c, line 60 there is the definition: extern void app_main(void);
and in line 135: app_main();

I am using esp-idf version: ESP-IDF v5.0-dev-3567-ge8d172eb87-dirty.

I started the build process with: idf.py flash monitor.

Can you please advice me how to get this build working?

If I started out using one of the templates that already had display, then the quality was good (It is white and bright, fonts are readable). But if I started out from a non-display template, the LCD quality was not quite there (the display is not as bright and has a light green color, fonts are very poor).

What settings in the menuConfigure or else where that I need to check for?

In one of the pictures from the docs, you showed a clock. Was it part of the factory_demo?

Hi,
I have followed some tutorials, and do

idf.py -p COMX build flash

... things go well.
But one day later, when I open my PC again, trying to run

idf.py -p COMX monitor

I got

serial.serialutil.SerialException: Cannot configure port, something went wrong. Original message: PermissionError(13, 'A device attached to the system is not functioning.', None, 31)`

I have tried to change my COM number or uninstall&&reinstall the driver of the serial, but nothing works T.T
Any ideas? Thx.
P.S. win10 env~

When building the "factory_demo", the build script is using "cp" on windows instead of "copy" during the "move model" task.

Hi,
Would it be possible for a matter (project chip) example app to be provided? I have been successfully prototyping with the esp32 development board and matter by following this example code in the matter open sourc library:
https://github.com/project-chip/connectedhomeip/tree/master/examples/all-clusters-app/esp32

I would like to try this code on the new esp-box but I suspect it may work but would not provide the Ai voice activation and UI that Is in the "out of the box" firmware?

If there were plans to provide a matter enabled esp-box sample application I would really appreciate that as it would safe loads of time and I suspect others would be interested too.

many thanks

Trying to incorporate sd card with the mp3_demo for the S3 Box. I could get the mp3_demo to play mp3 on the sd card with no problem. Except the UI elements would not show up. And vice versa if I got the UI working then the sd card will have issue.

The problem is down to these two initialization functions:
lv_port_init for LCD and spi_bus_initialize for the sd card.

Any hints what needed to be done?

Here are the errors. (Based on the sd card was initialized first)

Hi,

I installed from sckratch new ESPIDF and EClipse plugin for ESP32, imported projects from Examples folder on ESP32-S3-BOX GIT, but when I build whatever example I get this message during compiling:

I2C read error is not handled correctly as ret_val == ESP_OK and data_len > 0 is not checked here:

This will cause that tt21100_read will be called with data_len == 0

esp_err_t i2c_master_read(i2c_cmd_handle_t cmd_handle, uint8_t *data, size_t data_len, i2c_ack_type_t ack)
{
...
    ESP_RETURN_ON_FALSE(data_len > 0, ESP_ERR_INVALID_ARG, I2C_TAG, I2C_DATA_LEN_ERR_STR);

While going through those examples for the Box, I manage to copy and paste my way through a talking clock in Chinese.

esp-s3-box分别在esp-box仓库与esp-skainet仓库各有一个bsp，区别在于esp_board_init文件，部分函数名也有细微区别，例如esp_audio_play()与bsp_audio_play()，在一个project的component中同时包含两个bsp，编译时有概率会导致函数重定义。

I think it should be possible to run esp-box examples on S3 dev boards. I would like to reduce the partition sizes and remove some features such as playing music files, codec staff and even the AI voice recognition.

I've tried to make these examples work on the ESP32-S3-DevKitM-1 dev board that has 8 MB SPI flash with LCD connected to GPIO but the device keeps resetting for the image_display example and shows invalid header: 0x00010001 in the terminal for the factory_demo example.

This should be possible so I can start a proper development using these examples as a starting point since the esp-box and the S3 dev boards has the same chip.

Actually all I need is a working LVGL GUI with 3 physical buttons, wifi setup and ESP BOX mobile APP integration. By the way, how can we modify the ESP BOX mobile APP?

How can this be achieved? Any help would be appreciated.

Just for your info:

It did not (yet) cause me a problem:

The factory_demo example adds in CMakeLists.tst, line 16 $ENV{IDF_PATH}/examples/common_components/led_strip.
In the latest version of es-idf, the common_component led_strip has been moved. It existed before in esp-idf/examples/common_components, however: in the README.md of that component was stated the warning: Please note that this component is not considered to be a part of ESP-IDF stable API. It may change and it may be removed in the future releases.

In the latest version of esp-idf there I found a component led_strip in the esp-idf/examples/peripherals/rmt folder.
I suggest to you to modify line 16 to: $ENV{IDF_PATH}/examples/peripherals/rmt/led_strip.

For my application I've been looking at using mono mp3s for size, and because the es8311 codec is mono output only.

Would there be interest in a PR to switch the mp3s to mono, reduce the partition size to reduce programming, and the code to properly handle the mono mp3s? This part isn't too tricky but did require some test and debug and it could help the next person.

I'd like to get the ok that the idea made sense to the maintainers here.

How do you display Chinese text? I flashed my box with the Chinese firmware version. The factory_demo came with the CN firmware is in Chinese. But when I modified the image_display example to display Chinese text (I just supplied the file_name with Chinese string), it just displayed all with a strange symbol. The log showed in Chinese fine. Any hints?

Describe the bug

Compiling examples/rlottie fails x

To Reproduce

Compile latest LVGL on master with lottie library enabled in sdkconfig
lv_lib_rlottie added as a submodule under lvgl/lv_lib/lv_lib_rlottie

LVGL otherwise works as intended, but havent been able to get it to compile with the lottie option in the sdkconfig. Very interested in trying on the S3 specifically to see how large of a lottie animation can play on a 240x320 SPI TFT (ESP32 was not performant enough to play larger than 120x120 animations)

Expected behavior

Will not compile

rlottie_capi.h is a dependency from the full rlottie lib (also in lv_lib_rlottie)

Screenshots or video

Hello, I just received the ESP32-S3-BOX. Following the recommendations I was hoping I could upgrade the latest firmware according to these instructions: https://github.com/espressif/esp-box/blob/master/docs/firmware_update.md Although I have used this tool successfully multiple times on various other ESP devices, it does not work here. And yes, I also tried holding the boot button etc. It initializes the upload:

AP: 7CDFA1E1C781 STA: 7CDFA1E1C780
BT: 7CDFA1E1C782 ETHERNET: 7CDFA1E1C783

... and then I always get this error:

Uploading stub...
Running stub...
Stub running...

is stub and send flash finish

Is there any other thing I could try? It's not the cable or computer as I was also able to flash other firmware onto it (Tasmota via the Tasmota Web Installer for instance).

Thank you for your help!

我在淘宝乐鑫店买的ESP-BOX。收到后，我有两个问题想知道。期待您的回复
I bought the esp-box in Lexin Store on Taobao. After receiving the goods, I have two questions to know. Looking forward to your reply

  1. 我给开发板上电之后，使用”Hi 乐鑫“唤醒了开发板，屏幕也显示唤醒成功了，但是扬声器并没有回复词”好的“，这是否是正常现象，我不确定这是不是扬声器有问题
  After I give the development board power, use "Hi Loxin" wake up the development board, the screen also shows the wake up success, but the speaker did not reply to the word "good", this is a normal phenomenon, I am not sure if this is the speaker has a problem
  2.我唤醒开发板之后说一个命令词，就得再次唤醒，但是我看说明书可以体验连续语音识别，出厂固件可以连续识别吗？怎么进入连续识别？还是说是要我自己代码开发固件烧进去才能连续识别？ 
  After I wake up the development board and say a command word, I have to wake up again, but I see the manual can experience continuous speech recognition, factory firmware can continuous recognition? How to enter continuous recognition? Or do I have to develop my own code to burn the firmware in order to continuously identify?

Hi,

I have a custom LCD board with an ESP32S3 using LVGL. Previously, I had been building with an ESP32.

I was wondering what it would take to port the LVGL demos from the S3Box to this custom LCD.

The custom board uses an ST7789 display driver. Resolution is the same 320x240.

Pinout for my board is:
MOSI - 9
MISO - NC
SCLK - 19
CS - 47
DC - 16
RST - 17

I've compiled it, but cpu will not start as expected. I've also tried making the necessary changes from the original ESP32 project I've been working on, but to no avail (Boots as expected and starts on its main loop, but doesnt display to screen with the below pin changes)

I've adjusted, in the SDKCONFIG, the HMI Board Config such that:
HMI Board -> Custom HMI Board
Select LCD Interface -> LCD_INTERFACE_SPI
I2C GPIO Config (Unchanged)
SPI GPIO Config ->
SPI CS -> 47
SPI MISO -> 0 (NC?)
SPI MOSI -> 9
SPI SCLK -> 19

In esp32_s3_box.h:
#define GPIO_LCD_BL (GPIO_NUM_NC)
#define GPIO_LCD_BL_ON (1)
#define GPIO_LCD_CS (GPIO_NUM_47)
#define GPIO_LCD_RST (GPIO_NUM_17)
#define GPIO_LCD_DC (GPIO_NUM_16)
#define GPIO_LCD_CLK (GPIO_NUM_19)
#define GPIO_LCD_DIN (GPIO_NUM_9)
#define GPIO_LCD_DOUT (GPIO_NUM_NC)

Notably, when running the esp-box demo, I do not see the statement below printed.
(In doc)

(idf.py monitor)

When running the ESP32S3 on the previous repo I was using for esp32, I am able to pass this point without issue

Any suggestions would be much appreciated!

Can one use SD card with the S3 Box? Since the Box does not have a SD card slot, but it does have the USB-C. Or any other way?

在app_sr.c中，

AFE_FETCH_CHANNEL_VERIFIED感觉表示的是返回唤醒词识别成功，但在ESP-SR中显示的是返回音频通道确认，

这个音频通道确认是指什么音频通道确认？

I have an esp-box,I use the chip for dual-threaded work, but the chip keeps rebooting after programming.
And the error is shown above.
How can I solve this problem?

Can you set these two tasks to run on the same core? I have tried either both are on core 0 or core 1, but to no avail.

xTaskCreatePinnedToCore(&feed_Task, "feed", 8 * 1024, (void*)afe_data, 5, NULL, 0);
xTaskCreatePinnedToCore(&detect_Task, "detect", 8 * 1024, (void*)afe_data, 5, NULL, 1);

The mentioned Flash downloader might contain ransomware that tries to encrypt your hard drive. I am not 100% sure, but since this was the last executable that was installed on my PC, the probability is very high. The encryption starts from svchost.exe as soon as the system is idle for 15-30 minutes. The mentioned file does not need to be started, the installation process seems to be enough.

是用的官方的EdgeLine吗?

另外问下font_cmd_cn_36.c里的字体也是设计器生成的吗?能提供下字体名吗?

我这边同时购买了s3-box跟se-box-lite裸板,看了电路原理图跟s3-box对比应该是一样的屏幕接口,区别只是是否支持触屏.我把s3-box的屏幕的排线插到了Lite裸板上,为啥点亮不了屏幕呢?代码里我注释了触控驱动初始化（bsp_tp_init）

lite出厂例程有吗?生成的固件也行阿..

谢谢

Can it be done? Has anyone done it already? Any pointers?

我注意到，ESP_BOX设备端需要和ESP_BOX APP来配套使用，设备厂家可能使用ESP_BOX进行Claim；终端用户需要使用ESP_BOX来进行配网和user Mapping。或者是其他的使用方式，那么，ESP_BOX APP会开源吗？

Hi downloaded https://github.com/espressif/esp-box/releases/download/v0.2.1/ESP-Box_Demo_EN_V0.2.1.bin and flashed.

I have spent over ten minutes several reboots to get only 3 recognitions with worry that my neighbours may be thinking I have gone mad.

If you do manage the wake word then the command turn on/off light works great.
Actually getting the wake word to activate is another matter in a silent room.

I have a feeling it could be your dataset and now it actually has a english male voice it doesn't fit well or this firmware / model is not good.
I have no problems recording some samples if you tell me format and sampling rate...
Maybe community members could contribute if its merely a esp32-s3-box dataset accent problem.

Actually with more playing seems you need to be 2-3 meters away (further the better) for it to work relatively well if you pull the unit out on place close on your desk it doesn't work well maybe AGC?
Maybe its as simple as the MAP of mic spacing is 50mm whilst the box is 34mm, dunno but currently does not seem to be well.

The hardware design and software of the esp-box is brilliant and is really polished but the results currently of ESP_SR wow I really don't want to comment and due to the module being a .a with no source code there is little I can do, but wait fingers crossed.
ESP_DL lacks LSTM/GRU support which for audio is likely to be restrictive but always struggle what the xtensa hifi / esp32-s3 are capable of.
Maybe TFLite-Micro might come to the esp32-s3's rescue with vector optimisation as what is available and that its closed source is a huge stumbling block for anyone wanting to do ML on the S3

When searching for something else I came across this:

in file: esp-box/components/iot_button/button_adc.c
lines: 169 - 181

static uint32_t get_adc_volatge(adc1_channel_t channel)
{
    uint32_t adc_reading = 0;
    //Multisampling
    for (int i = 0; i < NO_OF_SAMPLES; i++) {
        adc_reading += adc1_get_raw(channel);
    }
    adc_reading /= NO_OF_SAMPLES;
    //Convert adc_reading to voltage in mV
    uint32_t voltage = adc_reading; //esp_adc_cal_raw_to_voltage(adc_reading, &g_button.adc_chars);
    ESP_LOGV(TAG, "Raw: %d\tVoltage: %dmV", adc_reading, voltage);
    return voltage;
}

I guess the name of the function should be: get_adc_voltage() like the word voltage is used four times inside the function.
However, maybe the function is never used. I don't see it defined inside the file: button_adc.h.

I find myself editing the esp-box mp3 example pretty heavily in order to support a new ui that wants to play a single file based on a user input.

If audio.c/.h would have an api like:

• play, pause, play_file

It would let me modify the ui to call play_file() based on button events, for example, and I think it could make the code a bit more reusable.

Other changes that would be made would be:

• event type for playback completion (so the caller can play the next song and maintain the functionality web ave today)
• move of file scanning and file list maintenance into the ui

I know it sounds like a bit of change, I'm having to make almost all of it here though, so if it was something of interest I could make it in the esp-box mp3 demo project and submit a PR.

Thoughts?

For the Box, since the SPI LCD display is internally wired as a bus master with GPIO 7 and 6, can any other SPI peripherals be able to connect to the Box at all if the internal LCD is active?

In your factory_demo, under the play_present function of the ui_player.c file:

`static void play_present()
{
ESP_LOGE(TAG, "play_present");
char filename[] = "/sdcard/song1.mp3"; // a mp3 song from SD card
start_sdcard_my(); //initialzing and mounting SD card.
// char filename[128];
// file_iterator_get_full_path_from_index(file_iterator, file_iterator_get_index(file_iterator), filename, sizeof(filename));
FILE* fp = fopen(filename, "rb");
if(!fp) {
ESP_LOGE(TAG, "unable to open '%s'", filename);
return;
}

audio_player_play(fp);

}`

It will play music fine. But the SR went haywire and no longer recognized ww or commands. Other functions seemed to be ok. Any suggestions?

Hi,
I am using a esp-box device to test live microphone feedback rejection. I have changed the original code of the algorithm example to output the audio processed through AEC directly to the speaker. But I am getting choppy/scratchy output. Is live AEC not supported by this board? Or am I doing something wrong?
Thanks

Hi!
I have an esp-box, I used two thread on this chip.
And I copied the function play_mp3() in my second thread.Then I used a flag to trigger it.
However, every time I trigger it,it would stuck like this:

I (39665) main: start to decode /spiffs/mp3/warning.mp3
I (39679) main: audio info: sr=48000, bit=16, ch=1

I think the problem might be this line: "i2s_channel_t channel = (nChans == 1) ? I2S_CHANNEL_MONO : I2S_CHANNEL_STEREO;"
How can I solve this question?Thanks!

The part number in the schematics is wrong. The correct is ICM-42670-P and, not ICM-42607-P.
