How to enable CONFIG_SPIRAM_SUPPORT in Arduino

[tanmanh0707]

Hi Bodmer,

I'm using esp32-s3 n8r2 which has 2MB PSRAM and I want to use it for the tft display.
I read the source code and there is a macro like this:

#if defined (ESP32) && defined (CONFIG_SPIRAM_SUPPORT)

CONFIG_SPIRAM_SUPPORT is a configuration in Kconfig if esp-idf is used. However, I'm using Arduino platform so I cannot enable this configuration.
Could you please let me know how to enable this CONFIG_SPIRAM_SUPPORT option using Arduino?
And only this option is enabled will force the library uses PSRAM using ps_calloc, isn't it?
I'm sure my board has PSRAM with psramInit and psramFound returns true.

Thank you very much,
Manh

If the SPIRAM is enabled in the Arduino IDE then the library will automatically use SPIRAM for sprites.

Dear Bodmer,

As I read somewhere, in latest arduino esp32 version, if PSRAM is enabled. it automatically uses PSRAM in every malloc, calloc without calling ps_malloc, ps_calloc. Is this what you mean?

Best regards,
Manh
