Official development framework for ESP32. Why you probably haven't used the 4MiB PSRAM available on some ESP32 Boards. First some packages need to be installed. Note that the resulting string is usually bigger than this, and it is always longer than 5 bytes; that's to guarantee that the string data is stored in a common buffer and not inlined into mjs_val_t, thus the buffer can be used as an "output" buffer: a string can be passed to some function which will alter. COM_PORT_ESPTOOL¶ Port to use for flashing device. The SPI RAM can be accessed in multiple methods: by just having it available as an unmanaged memory region in the ESP32 memory map, by integrating it in the ESP32s heap as ‘special’ memory needing heap_caps_malloc to allocate, or by fully integrating it making malloc() also able to return SPI RAM pointers. ESP32 §Eliminate Heap size 0. Anyway, to test it, I've cloned ESP32_TFT_library into new directory, configured for ESP32-WROVER-KIT v3, built and run it. However in constrained edge devices like ESP32, each bit counts, hence we need to look for lighter server component.
