Esp32 S3 is supported?

[mikadoryu]

As the title says, it is possible to use an esp32-s3 (those with 2 usb c ports). I'm trying to compile the code but I have problems with the DAC since it can't find the library.

Searching I found that the S3 apparently do not have a normal dac like the previous esp32

Unfortunately, I do not have an ESP32-s3 available for testing.

What do you mean by that? Do you mean that the ADC in the ESP32-s3 must be controlled differently in software?

but I have problems with the DAC since it can't find the library.

Sounds a bit like your Arduino IDE is not to be setup correctly. Have you installed the Espressif library like, e.g., described here?

[corrados]

That is bad news. So, it seems the ESP32-S3 is no longer compatible to the hardware register definitions I use. Therefore, the ADC code has to be rewritten for the ESP32-S3.

[corrados]

FYI, I have just ordered an ESP32-S3 developer board in China. It may take up to two month until it arrives. As soon as I have it, I'll try to run Edrumulus on it.

[mikadoryu]

It's good that you want to review the errors with the S3.

One question I have is that the functions init_my_analogRead() and my_analogRead are because there was a delay problem in analogRead() do you know if this still happens in the libs for s3?

[corrados]

No, I don't. But I will find out :-)

[corrados]

I've now implemented a fix for the ESP32-S3 compilation errors. This I could do without having the hardware available. I now use the analogRead() function for the ESP32-S3 but I assume that it is way too slow for Edrumulus and that I have to implement my own analog read function similar to what exists right now for the old ESP32.
But at least you could give it a try now.

[corrados]

I just read in the Discussion overview that your question is still on "unanswered". So, I'll answer it now:

No, ESP32-S3 is not yet supported by Edrumulus. But as soon as I have one, I'll try to get Edrumulus running on that device :-).

[corrados]

An initial support for ESP32-S3 is done now. You can checkout the latest code on Git main branch and give it a try.
Up to now, I just checked that I get correct ADC readings from all configured inputs. I do not have the front end (i.e., the three resisters) available for the ESP32-S3, so I cannot do a test with a real pad. But by just touching the ADC connectors with my fingers gives me a lot of MIDI messages. So, in principle it should work now.

[corrados]

Today, I tested the ESP32-S3 with a real front end where my PD-85 mesh pad was connected and it worked just fine.

[corrados]

Is that because GPIO 0-3 are used for something?

Yes, that's the problem.

I'd love to have the option of your advanced position sensing - that 3 piezo setup is something I've wanted to experiment with, and you've got it working well :)

Oh, that code is still very experimental. There are still a lot of TODOs in the code.

[3hhh]

I'm kind of tempted to go to BAT56S's for the clamping diodes as it lowers the component count, but I don't think it would save space so it's probably not worth it

The clamping diodes need to have a forward voltage matching the operating range of the board. You can of course go outside of the operating range and it may work for a while, but your board may as well die once the clamping diodes kick in.

@corrados : Experimental code is all good - this already such a good platform to experiment with, so I'm very happy.
@3hhh : It's a good point. The bat54s (sorry, typo in first post) has a very very similar forward voltage, so it should be fine. It is fairly small SMD though so makes soldering a little tricky. But 2 diodes per package is nice and compact.

[peteallenm]

I've spun a board and sent it off to JLPCB (I went SMD in the end as it's easier to solder)
I've put it on my GitHub for now, and if it works I could do a pull request if it's helpful.

[corrados]

Sure 👍 Just name it "prototype_peteallenm" in the hardware directory.

Native USB is working with TinyUSB library. Se this PR #136

when i compile with esp32 s3 i've got errors
with a normal esp32 everything ok

C:\Users\M_le_\Documents\Arduino\libraries\edrumulus-main\hardware.cpp: In member function 'void Edrumulus_hardware::init_my_analogRead()':
C:\Users\M_le_\Documents\Arduino\libraries\edrumulus-main\hardware.cpp:457:3: error: 'adc_power_acquire' was not declared in this scope

[corrados]

Thanks for reporting. Should work now. Please try again.

[mike76700]

same errors with new file

[mike76700]

it was a loose wire
i've got note 38 but still the same nothing comes out on the daw by virtual port

[corrados]

If you see notes in the Edrumulus GUI, we know that the communication between Edrumulus GUI and the ESP32-S3 works just fine. So, only the MIDI port creation under Windows seems to have an issue.

What I basically do is to create a MIDI out port in Windows with pytemidi.Device("EdrumulusOut") and send the MIDI data with midiout.send(bytearray(serial_message)). That works fine on my Windows.

Either your Windows system configuration does not allow to send MIDI or your pytemidi installation has a problem.

[mike76700]

reinstall pytemidi it's the same
,anything to change ?
perhaps uninstall loopmidi and hairless
i make a try in another computer as soon as possible to see if it's my computer.

[mike76700]

a way to use it without virtual port?
just for settings?

[corrados]

For settings, you can use Edrumulus GUI as you have it right now. As said above, the communication with the ESP32-S3 seems to work fine and therefore the settings adjustments should also work just fine.

[mike76700]

can i use it without virtual port creation?

[corrados]

Why do you want to remove it? Do you get issues in your system if it appears? I thought that you could simply ignore it if you do not need to use it.
