Getting the project started on the ESP32 Audio Kit and solving occured issues

Could you give me a step by step guide as a beginner. I want to repeat the scratch project, I ordered the AS5600 and the ESP32 Audio Kit, I see the following way: 1) uncomment the scratch code,
2) upload the firmware to the board
Question: Which pins should I connect the AS5600 board to?
Is it possible to load samples from the SD card on the buttons on the board when loading?

[marcel-licence]

The first step would be to identify the correct version of the ESP32 Audio Kit.
There are different defines to select the board: https://github.com/marcel-licence/ML_SynthTools/blob/main/extras/ml_boards.md

In case you have the ES8388 equipped there is also a configuration possible: https://github.com/marcel-licence/ML_SynthTools/blob/main/src/boards/board_audio_kit_es8388.h

To test your configuration you can compile the project as it is (with the correct board chosen) upload it and check if you get any audio output.

After you can activate the AS5600_ENABLED define.
In the board_audio_kit_...h you will find the I2C pin definitions. Maybe the following configuration is used:

#define I2C_SDA 18 /* I2C shared with pin header */
#define I2C_SCL 23 /* I2C shared with pin header */

Otherwise you can chose your own pins to connect the AS5600. It need 3V, GND, SDA, SCL.

Key1 and Key2 can be used to switch between samples. For that I used the modification: https://www.youtube.com/watch?v=r0af0DB1R68

Hope this helps to get the first steps done

Hello man. plz help me

when compiling the sketch, an error occurs, in the config.h file I selected the desired config, there is a file along the way! but why does he say that there is no file?

In file included from C:\esp32_midi_sampler\esp32_midi_sampler.ino:105:0:

C:\DOCUME1\Admin\LOCALS1\Temp\arduino_build_821342\sketch\config.h:93:23: fatal error: ml_boards.h: No such file or directory

compilation terminated.
exit status 1
ќшибка компил€ции дл€ платы ESP32 Dev Module.

[marcel-licence]

For compiling in config.h you can select the correct board:
//#define BOARD_ML_V1 /* activate this when using the ML PCB V1 */ //#define BOARD_ESP32_AUDIO_KIT_AC101 /* activate this when using the ESP32 Audio Kit v2.2 with the AC101 codec */ #define BOARD_ESP32_AUDIO_KIT_ES8388 /* activate this when using the ESP32 Audio Kit v2.2 with the ES8388 codec */ //#define BOARD_ESP32_DOIT /* activate this when using the DOIT ESP32 DEVKIT V1 board */

Using the ESP32 Audio Kit with AC101 might have a copper antenna. The other board usually has a black coated one.

After uploading there is also a LittleFs Data upload in the Arduino menu.

You can check the serial monitor after startup for more information. It might be that the codec has not been found in some cases.

Arduino allows to open a serial monitor to show messages during the execution of the sampler software

[dynai79]

also tried different boards
ESP32 and AC101

no sound.....

Arduino allows to open a serial monitor to show messages during the execution of the sampler software

please help me, I've been scratching my head for 10 hours already, the sketch is uploading to the power supply, I'm uploading a sample via LIttelFS (default)
and still no sound, tried all variants of AC101 and ES8388 audio kits. there is silence in the headphones, where is the problem and what have I been doing wrong for 10 hours I can’t figure it out.

I guess you have the ESP32 Audio Kit with the ES8388 codec. There is only one configuration with AC101 with didn't work.
In https://github.com/marcel-licence/ML_SynthTools/blob/main/src/boards/board_audio_kit_es8388.h you will find
#define ES8388_CFG_I2C 1
You can change the number. You can change the number and try until the ES8388 connection does not return a failure.

Regarding the the error:

02:27:29.141 -> E (565) esp_littlefs: mount failed, (-84)
02:27:29.141 -> E (569) esp_littlefs: Failed to initialize LittleFS

it seems that you didn't use the LittleFS Data Upload:

This is an additional step to get the samples on the ESP32. SD Card is not required for the first steps.

When the ES8388 init error is gone and the FS error is gone you can concentrate on the audio output. If you get no output at this stage you will find
#define ES8388_CFG_I2S 4
in https://github.com/marcel-licence/ML_SynthTools/blob/main/src/boards/board_audio_kit_es8388.h

Trying different numbers will select other pins for I2S. There are also different possibilities.

Once you find one configuration you can use it in future.

I am using LittleFS Data Upload

my board has a black antenna, most likely I have an 8388 driver, thanks for the advice, now I will sort through the numbers in the line #define ES8388_CFG_I2C 1 and #define ES8388_CFG_I2S 4 tell me what is the maximum value?

Tell me, is there somewhere documentation on controlling the buttons from the board? let's say how to record a sample through the built-in microphone and play it back? only using board keys

[dynai79]

at the moment I do not have resistors and a soldering gun on hand. Can I play at least 1 sample without soldering?

[marcel-licence]

You can pass MIDI via serial. There are tools but I do not have an exact description. The playback can be also started by calling NoteOn which should be found in the Setup function. For the example there is a loop setup which should generate some noise. Did you get any audio output yet?

[dynai79]

I hear the sound of a vinyl record.

[dynai79]

im enabled is AS5600

You can define it by yourself for example by adding:

#define I2C_SDA 18 /* I2C shared with pin header */
#define I2C_SCL 23 /* I2C shared with pin header */

[dynai79]

Вы можете определить его самостоятельно, например, добавив:

#define I2C_SDA 18 /* I2C shared with pin header */
#define I2C_SCL 23 /* I2C shared with pin header */

im use 18 and 23 pin

[dynai79]

im add to config.h

#define I2C_SDA 18 /* I2C shared with pin header /
#define I2C_SCL 23 / I2C shared with pin header */

There is a division by zero:
Guru Meditation Error: Core 1 panic'ed (IntegerDivideByZero). Exception was unhandled.

You can put the

Into the exception decoder (can be found in the menu).
This will generate some useful information

66614090277__93EC2C2E-9A0B-452B-A341-35ED237198DD.MOV

I managed to compile with the AS5600 turned on, like this my LED is blinking, did I do everything right?

[dynai79]

Sound headphones
https://user-images.githubusercontent.com/34723184/153306485-0be2aecb-886d-4db0-9100-abb343e427aa.MOV

[dynai79]

can you tell me how to enable the sample and send it to as5600?

[dynai79]

The LED lights up like you see in the video! already good news, I need to immediately include 1 sample when loading, in order to test the work of as5600

66614503037__0EF849CA-79C3-47B2-A82C-D89737EE590F.MOV

[dynai79]

I’m add configuration or as5600 add to esp32_midi_sampler, and compilation completed!

[marcel-licence]

From your video I can see that a wave file has been loaded into the RAM. That looks good.
The buttons can only be used when the board has been modified (https://youtu.be/r0af0DB1R68)

Your three defines from the screenshot in esp32_midi.sampler.ino should be placed in config.h instead. Otherwise it might not work as expected.

in as5600.ino there are some lines starting with
//Serial.printf
you can uncomment the lines to get some output when using the as5600 if there is something which does not work regarding the as5600.

[dynai79]

I got the result. when I spin the magnet. the values change. if I don't twist. they are fixed. Already a small victory for me.

but there is one problem. if i line
#define AS5600_ENABLED /* can be used for scratching /
#define I2C_SPEED 1000000
#define I2C_SDA 19 / I2C shared with pin header /
#define I2C_SCL 23 / I2C shared with pin header */
I put it in the config.h file, then KEY3 does not work for me and I cannot choose to play the sample! and if these lines are in esp32_midi_sampler then I can control KEY3 but AS5600 does not work

while in the headphones I hear noise

I've been scratching my head for a few days now. not enough knowledge to do it completely on your own

66629750188__83AEBC8A-9436-408D-BEE3-0C9267B87A3C.MOV

[dynai79]

thank you very much for your help! you have a very cool project! I finally got it. but there is one problem. my sample plays back at a high pitch. don't you know why? and my sample turned upside down after uploading

[dynai79]

I experimented in the lines in order to adjust the pitch, but nothing worked out for me. the sample plays very fast. I'm trying to work with your standard sample. if I upload my own, then it’s generally a squeak. at least I can hear yours. Another problem is that I got a reverse. twist in the opposite direction, the sample is played forward.

static float lastPitch = 0;
static float pitchOffset = -100.0f;

float AS5600_GetPitch(uint8_t oversample)
{
float pitch = sumCh;

sumCh = 0;
pitch *= .25f;
pitch /= oversample;
if (pitch > 50)
{
    pitch=50;
}
if (pitch < -50)
{
    pitch = -50;
}

for (int i = 0; i < oversample; i++)
{
    lastPitch = pitch * 0.05 + lastPitch * 0.95;

[marcel-licence]

For inversion you can add:
pitch *= -1.0f;

In general the pitch is depending of the rotation speed (rotation per second). You might get better results if you have more mass to move (like a disk). With lover speeds and more mass the sound will be also more clearer. Sounds great that you found some solutions =)

You can also vary the smoothing in line:
lastPitch = pitch * 0.05 + lastPitch * 0.95;
More smoothing for example with:
lastPitch = pitch * 0.01 + lastPitch * 0.99;
That would make the reaction to pitch changes slower.

[dynai79]

pitch *= -1.0f; Instead of or next to? pitch *= .25f;

[marcel-licence]

You can put it next to. Changing the sign should invert the playback direction. I didn't try it yet but I think that should work.
To make is slower (lower pitch) you can use for 0.25f a smaller value instead. In case the final calculated result of all calculation equals 1 you will get the original playback speed.

[dynai79]

Вы можете положить его рядом. Изменение знака должно изменить направление воспроизведения. Я еще не пробовал, но я думаю, что это должно сработать. чтобы сделать медленнее (более низкий шаг), вы можете использовать вместо 0,25 f меньшее значение. В случае, если окончательный расчетный результат всех вычислений равен 1, вы получите исходную скорость воспроизведения.

instead of 0.25 I tried different ones and on 5.10.15 none of this helped

[dynai79]

#define ES8388_CFG_I2C 2
#define ES8388_CFG_I2S 5

my SDA and SCL i2c is work

[dynai79]

pet_boottle.wav works for me. but I can't upload my sample. I set the frequency as your sample. but all the same I hear only a squeak. tell me where to look

[dynai79]

Tell me how to convert the sample correctly. which codec and bitrate to choose, as well as mono or stereo? I get a sample of very poor quality

[dynai79]

A friend, please tell me about the sample, I twisted the skewer yesterday. and bitrate and codec, then my sample is very fast compared to yours, I adjusted the pitch, more less, but the sample is very grainy and not of high quality

[marcel-licence]

I used 44100 samples/second s16 mono for samples. In that case it should played like recorded

[dynai79]

Я использовал 44100 образцов в секунду s16 mono для образцов. В этом случае он должен воспроизводиться как записанный

I did everything exactly as you said, but with these settings I hear a squeak

[dynai79]

Everything. I figured it out. this converter worked https://www.media.io/convert/mp3-to-wav.html indicating 64kb.sec

[dynai79]

I am very satisfied! Marcel, thank you very much, firstly for your excellent project, secondly for your support, it helped me a lot, now I will design a scratch fader to use it to its full potential, I have a skill in scratching, as soon as I do I will record a video and send to github

[marcel-licence]

Sounds great! Yes the fader is missing. I could use the easy moving cross fader of my controller. A stand-alone control would be very nice. I am looking for the video =)

[dynai79]

IMG_0195.MOV

Hi, my prototype in video )

[marcel-licence]

Hi, that is very cool!! Thank you so much for sharing.
How does the fader work? Looks like you are using something optical.

[dynai79]

• [ ]
  
  Thank you again so much for the project! I wouldn't have any joy without you! yes! I built the simplest fader on an optical pair, such a module (img) and this module sends a signal to a relay that turns off the sound channels (left and right two relays), also put a sound amplifier board so that it could adjust the sample volume relative to the bit

[dynai79]

The funny thing is that the disk is from the USM machine :)

[marcel-licence]

Funny idea, I looked up the brand printed on your disk and was surprised xD

I could imagine that it might be possible to feed in the out signal from the optical pair to the ESP32 -> voltage conversion would be required using a voltage divider to ensure that you do not go above the power supply of the ESP32. In that case you could control the volume via software.

I am very happy to hear that. It is also very nice to see what results can be created with this basis.

[dynai79]

Marcel, I plan to use your firmware at full capacity, I want to make a midi controller myself, and connect it so that I can use all the functions, if there are problems, will you help?)

[marcel-licence]

Sounds great. My time is limited but I always try to help. I could also imagine to include some new things in this project soon. For example some additional effects which can be part of the SynthTools library and easy integrated and controlled by all other existing projects.

Just feel free to open new discussion for upcoming topics. I can imagine that you can also get input from the community
