-DBOARD_HAS_PSRAM default in Arduion for ESP32-S3?

Board

ESP32-S3

Device Description

ESp32-S3 Xiao

Hardware Configuration

Stock ESp32-S3. Mostly Xiao S3 it seems.

Here is our example of our I2S driver + instructions for users. It would be awesome if you could update the platform json files to include this build flag by default.

Description

Hi @Jason2866. I've spent some tonight to simplify instructions for the ESP32-S3 I2S driver that we are running for 16 parallel WS2812 strips.

My ask is this: Can -DBOARD_HAS_PSRAM be the default on ESP32-S3 for ArduinoIDE? I think it is one of the platform.json file defintions. I'm willing to do the work if you can point me to the right one.

Right now, the only way the users can use our I2S driver is if they use platformio.ini and pass in the above build flag. I think that the PSRAM should be enabled by default on ArduinoIDE.

I looked into it and FastLED probably can either enable the psram during runtime or on the first call to FastLED.show(), or otherwise lazily. This seems to be the last issue before the massive 16-way parallel driver can be used on ESP32-S3 on a stock build on ArduionIDE.

Anyway, I wanted to put this on your radar as something that is important. It certainly would be important to our users, as most of them use ArduinoIDE. Your S3 sure is a beast and I'm fun using it for heavy floating point computations. For example, check out our WaveFx that I added recently.

@zackees Can't speak for this repo and decisions made for default settings. Speaking for pioarduino, if a board has PSRAM and it is not enabled in the regarding boards manifest i consider this as bug in the boards manifest and a PR in repo pioarduino is very welcome to fix this!

To enable PSRAM for a not specific board is not recommended since the GPIOs which are used for PSRAM are blocked or at least show glitches when trying to use (when the board has no PSRAM).

The referenced board already has PSRAM as default setting https://github.com/pioarduino/platform-espressif32/blob/main/boards/seeed_xiao_esp32s3.json
