@ -60,6 +60,12 @@ CIRCUITPY_BLE_NAME
~~~~~~~~~~~~~~~~~~
Default BLE name the board advertises as, including for the BLE workflow.
CIRCUITPY_PYSTACK_SIZE
~~~~~~~~~~~~~~~~~~~~~~
Sets the size of the python stack. Must be a multiple of 4. The default value is currently 1536.
Increasing the stack reduces the size of the heap available to python code.
Used to avoid "Pystack exhausted" errors when the code can't be reworked to avoid it.
CIRCUITPY_RESERVED_PSRAM
~~~~~~~~~~~~~~~~~~~~~~~~
On boards with Espressif microcontrollers with PSRAM (also called SPIRAM), permanently reserve a portion of PSRAM for use by esp-idf.
