Fixes platformio.ini for the ESP32 S3

Hi, thanks for the update.

A few requests from my side: 1/ I would prefer to stay with [email protected], simply because it is a well-tested version especially with respect to I2S (audioreactive). 2/ Can you explain a bit more about compilation errors you have? I never experienced any. 3/ It seems that the previously used platform_packages version has been removed. Instead of fixing another version, it should be sufficient to use platform_packages = (empty line) as this means "use the default package".

Thanks again for the contribution and research you did!

Hi, regardling about [email protected], you can check the linked issues (https://github.com/platformio/platform-espressif32/issues/912 and https://github.com/platformio/platform-espressif32/pull/914), but in short, there's an issue while compiling for ESP32-S3 saying that the sdkconfig.h doesn't exists. I'd recommend you to see both issues for more details ;) but it seems that it's only regardling to the ESP32-S3. If you want, I'll leave my override.ini down here so you can test it

platformio_override.txt

(please remember to change its extension to .ini)

For the second point, I only got two compiling error, the first one was about the sdkconfig.h, and the second one about the missing package which was removed. While for the third point, I didn't know that it was able to use the default package, so I don't think it's a problem. After changing both lines, the build was completely straight forward

Really I am very careful with updating espressif releases, from bad experience. Our Chinese friends seem to be very innovative sometimes, however not good with not breaking existing functionality. The I2S driver is an example. I only found it (barely) working in ESP-IDF 4.4.1, while its somehow broken in 4.4.2 and 4.4.0. Similar for arduino-esp32: v2.0.4 works well, however using v2.0.5 leads to firmware that crashes (boot loops) on my -S3.

After a bit of research, it seems there are two "main variants" of ESP32-S3:

• One with "classic" qio flash and no PSRAM. I've actually compiled for it earlier today without "sdkconfig.h not found" errors.
• One with octal flash and PSRAM. These seem to need memory_type=qspi_opi to work.

My suggestion is to create two platformio.ini entries for S3:

• the existing one for "S3 with qio", and
• a new one for supporting your board that seems to need a newer espressif release.

The "S3 with qio" should only get the platform_packages = change, while your new entry could use platform = [email protected]. I will also double-check that the exisiting [env:esp32s3dev_8MB] still works for my board.

@blazoncek what do you think?

however not good with not breaking existing functionality.

Yeah, you're right there hahaha. I lost most of my hair because of them.

• One with octal flash and PSRAM. These seem to need memory_type=qspi_opi to work.

Seems that you're right. My board (the TinyS3) actually has 8MB extra QSPI PSRAM, so maybe you're right, they overlook that scenario and maybe updating to 5.2.0 may produce compiling errors for non-PSRAM S3 boards.

Sadly, I cannot test the AudioReactive feature as I only have one TinyS3 (and they're quite expensive for me actually) and I'll not use that feature on my project :(

No problem - if you update the platformio.ini entries, then I can verify (over the weekend) that audioreactive usermod still compiles for both TinyS3 and previous S3 environments.

[JPZV]

Sorry for the delay. I added the new environment for the PSRAM version, though, I'm not sure if that's how it's suppose to be added to the platformio.ini as this is the first project where I use it.

If there's anything else that I can do, please let me know

[blazoncek]

As much as I'd like to test (or review) I lack S3. 😄 As for platform update, I agree with the notion that updating it too soon may cause unnecessary headaches. I was testing 5.1.1 for about 6 weeks before deciding to recommend it (for S2 & C3). I still do not recommend it for classic ESP32.

[softhack007]

Hi again, I still have problems to compile with your new environment "out of the box".

• Error: Unknown board ID 'esp32-tinys3'

If I use board = esp32s3box instead, compilation starts but later aborts with 'esp32_adc2gpio' was not declared in this scope

Any Ideas?

So sorry, I misspelled it, it should be um_tinys3, but, for some reason, it also fails with the same error ('esp32_adc2gpio' was not declared in this scope)

Funny enough, it can be compiled with esp32-s3-devkitc-1 (just like the non-PSRAM version) and it works on my board, but not sure if the esp32_adc2gpio could make some troubles with WLED (at least I can control sk6812 RGBW leds with it)

'esp32_adc2gpio' was not declared in this scope seems to be a problem with latest framework-arduinoespressif32 (and maybe in arduino-esp32, too). Maybe you should create a bug report for that project, as many -S3 targets are affected by the same issue.

As a quick workaround:

• edit C:/Users/user/.platformio/packages/framework-arduinoespressif32/variants/um_tinys3/pins_arduino.h
• comment out this line #define analogInputToDigitalPin(p) (((p)<20)?(esp32_adc2gpio[(p)]):-1)
• replace with #define analogInputToDigitalPin(p) (((p)<20)?(analogChannelToDigitalPin(p)):-1)

save, recompile, it works (for me).

[JPZV]

Thanks for the Workaround! Can confirm it compiles now and it works on my TinyS3!

I'll let them know right away!
